Best Multiprocess Welder Buying Guide- Shopping Secret

Buying an all in one welder is not easy. Purchasing the best multifunction welder online may seem impossible.

Relax!

That's not all true!

Some factors and shopping secrets will help you to buy the best one.

Let’s check out our practical and informative buying guide.

  • WELDING-PROCESS: Which combination is best?

First of all, you have to decide on the essential processes of a welding machine you need to get your job done. In general, MIG welding process will be one of them. However, the most common combination of a multi-process welding machine is MIG, TIG and stick welding.  This combination will cover a large variety of projects. It’s convenient having plasma cutting option in a multi process welder.

A good multi process welder is an ideal option for beginners and professionals who are looking for 3 in one welders or 4 in 1 welder to use for alloy, steel, stainless steel and even aluminum.

Some common popular combinations in this category are:
  • MIG/TIG/STICK- Ideal for most welding discipline
  • MIG/TIG/CUTTER-Ideal for work with a variety of metals and some basic construction work at the same time
  • TIG/PLASMA/STICK- Ideal to weld exotic materials
  • PLASMA CUTTING OPTION: Having this option is essential?

If you find a product that features the combination of TIG/ MIG/ Stick welding process, you can add it to your buying list. This combination will cover a wide range of the welding process of your projects at the DIY level. In addition to these welding processes, it’s convenient to prefer a machine that offers the plasma cutting option too. In some cases, plasma cutting may be the best substitute for the stick welding process.

  • AMPERAGE RANGE: How much amp is ideal?

The most important specification that you should take into account is amperage range.  Make sure the unit you’re considering to buy can provide enough output power to tackle your projects. A short range will limit your work to cut types of materials which you require to weld.

A welding machine with an amperage range between 150Amp to 230amp is ideal to weld ¼-inch aluminum to 24 gauge steel.  In general, if you’re a DIY or home user, it’s better to buy a multi-process welder having at least 150 amp power. If you need regular or frequent use at home or any project or for your automobile repairs, then the machine having 200-300 amp category will provide you enough amps of output to tackle the types of materials you’ll be using to weld. In fact, you should consider the types and thickness of metals that you’ll be working with when making a buying decision.

  • AC & DC CAPABILITY: Which power supply is important for welding?

The required and available power supply dramatically affects many factors when welding. It’s significant to determine which type of power supply the unit requires, and which power supply is available before choosing a multi-process welder.

In general, a specific type of welding process depends on either constant voltage or constant current supplies.  AC and DC capability plays a vital role in welding types. For example, the MIG and stick welding often make use of the direct current.

So, having a unit which is capable of both DC and AC output will give you the most flexibility in your welding process.  To weld tough material like steel, you’ll require direct current. A unit having AC capability will work better on self-oxidizing metal such as aluminum or magnesium.

  • USER-FRIENDLY INTERFACE: How much essential it is?

A complicated welding machine will exhaust your hours of time for learning how to set up or how to operate. If you’ve to make a lot of adjustments to the settings in the middle of your working process to run a welding bead is tough to manage. And the possibility is that the things may go wrong. Right?

So, you should choose a model which is easy to set up and adjust, easy to use and need less instruction to operate that are well laid out and easy to learn. Look for a machine with user-friendly interface and control. This will make it more convenient and will ensure you more control over the outcome of the job.

Look!

Some models feature digital and precise control. These models are great as you have the scope of fine-tuning. Some models also come with a clear display that will reduce errors and mistakes.

  • WEIGHT: Heavyweight or lightweight?

If you need to work on different DIY projects, home improvement projects or professional jobs where you have to move frequently, you should go for compact and portable multi-process welding machine that you can move and transport easily.  In these cases, a heavyweight device won’t be practical and comfortable to you as you can’t move it around without the welding/plasma cutter cart.

  • PRICING: Should I go for the cheapest multi process welder?

You may already have an estimated budget in mind. Right?

Remember!

Most of the multi-process welding machine is cheaper than purchasing the different units for different processes.

What do you want from your equipment?

Indeed, you expect to get the best value for your money and long-lasting performance.

More powerful units will undoubtedly come with expensive price tags. If you can spend more money, you should go for the best all in one welder that will offer more power and better features. Before making a buying decision, you should consider your working needs and your budget.

Benefits Of Using Multi-Process Welding Machine

Multi-process welders make it easy for welding operators to tackle a number of construction or fabrication jobs and projects in the shop, on the job site, or in the field without switching different power sources – saving you money as well as time. Find the one that’s right for your application.

Multi process welding machines are one of the most useful innovations in metal industries. They are unique in the design for the welding industries. This type of equipment combines several welding and cutting disciplines in one machine. Thus, a multi-process machine makes it easy for users to handle a variety of construction or fabrication projects and task without switching power sources. That will save not only time but also money.

In general, a multi-process welder offers TIG, Stick, MIG and flux-cored welding process as a part of what they can provide. This feature allows you to finish your entire project without the need to switch out the unit.

The primary advantages of using a multi-process welder are the versatility, convenience, space/portability, and the price.

  • Versatility: A single process unit never offers much versatility that the professional or even a DIY user requires typically. The most significant benefit of using a multi-process welder is its versatility. This unit allows the user to use the same machine for the various welding process. It provides the user with a wide range of tasks they can perform across a variety of metal types.
  • Convenient: This equipment makes it easier for users to tackle several tasks on the construction site or DIY or home projects. A multi-purpose machine can be easily adjusted to suit user’s specific needs. Without switching power switches or machines, the user can finish his task as fast. Beginners and professionals appreciate the easy to use control and quick response to shift the settings of the unit to switch from one process to another.
  • Price: Although some multi-purpose welding machine is expensive, if you consider buying individual welding and plasma cutting machine for the different process, a multifunction welder will cost less.
  • Space/ portability: Accommodating, storing and transporting different 3+ types of machines for different process requires more space. On the other hand, a multi- process welder offers all the various process from a compact size unit. Storing and transporting a single unit is the most convenient option.

Limitations Of Using A Multi Purpose Welders

Although a multi-process welder offers the user a wide range of advantages, this unit isn’t beyond disadvantages.

When we’ve tested various types of the multi-process welder, the only one common issue that we’ve found out is its weight. Some multi-process machines are heavy. We found some are more than 85 pounds. If you use it for industrial purpose, it’s not a negative issue. You may require repositioning the machine to reach different angles if you work on a large project. So, a heavy unit may be difficult to handle and move around.  A heavy unit just won’t allow you the range of motion and reach you need to accomplish that. It limits its portability.

However, if you’re a home user, it may be a little problem to move around.

Common Mistakes When Purchasing All In One Welding Machine

Here are a few of the more common mistakes people make when buying a Multi-process machine:

  • Unnecessary functions: If you only need to accomplish the basic welding operation, you don’t need to go for feature-rich welding machine. It’ll add significantly to the cost. To meet your basic operation needs, a unit with primary feature will do well. For example, if you don’t need to weld magnesium or aluminum, it’s not wise to go for a unit with AC capabilities. So, before choosing a model, consider your working needs and material you require to work with frequently.
  • Inappropriate input voltage: It’s essential to understand what your power capabilities are. Some units are compatible with both 110volt and 220volt.  The output at 110volt will be significantly less than at 220volt. There are also some single phase multi process welder and some features 3 phase welder. Before buying a unit, make sure to check the input power or voltage so that it matches up with your available power where you’ll be using the unit.
  • Cooling option: The larger unit may require a separate cooling tool to achieve the full output power from the welding machine. It'll also add to the cost. So, make sure the unit that you decide to buy features its own cooling option or you need cooling equipment to enhance its duty cycle as well as output.

Safety Procedures For Using Multi-Process Welding Machines

There are some safety procedures and fire-prevention measures that every welder must abide by when using any welding and multi-process welding machine.

Let’s have a look at some necessary safety procedures.

  • check
    Welding fumes are a common issue that causes breathing problems in welding machine operators. Although some problems are short- term, some may cause long-term illness like asthma. Internationally, welding fumes are described as possible carcinogens. Besides, burning is the most common injury associated with the welding process.                   Personal protective clothing can significantly decrease the risk of burns.                   Personal protective equipment for welders includes:
    • Safety glasses
    • Fire-resistant clothing
    • Welding helmet and leathers
    • Gloves
    • Shoes
    • Hood
  • check
    Operators must avoid wearing synthetic clothes because these type of clothes melt when exposed to extremely high heat. In this case, wearing wool clothes can be a better choice as it’s fire-resistant and durable.
  • check
    Operators should not roll up their pants and shirts as sparks can get trapped in the folds. They should wear pants outside of shoes or work boots that will protect particles from deposit inside the boots or shoes.
  • Safely goggles are one of the most critical safety equipment that operators should always wear under the welding helmet. If you use safety glasses instead of goggles, make sure they feature side shields.

How To Use Multi Process Welding Machine- Step By Step Working Procedure For Beginners

Welding is an art.

Yes. You heard the right thing.

It’s a delicate art. But it also needs sometimes and practices to learn appropriately. Once you have learned how to weld and how to use a multi-process welding machine, steel will be a blank canvas of invention for you.

This step-by-step guideline will help you to learn the basics about welding.

Step 1: Decide On The Welding Process

First of all, choose the appropriate welding process for the project you need to complete. MIG is one of the most precise and popular welding processes. It’s also the most straightforward process to learn. Other popular operations include stick welding (SMAW) and flux-cored arc welding (FCAW).

Step 2:  Create Your Own Welding Kits

The second step involves arranging the equipment to create a welding kit. Naturally, a welding machine is the first piece of equipment for the kit. It’s also the most essential machine so, you should decide on to invest in it.

You’ll also need a chipping hammer, some miter clamps, a pair of welding pliers, an angle grinder, shielding gas, some welding wire. A welding cart will be an excellent addition for welding machine portability.

Step 3: Stay Safe

Next, you’ve to arrange personal protective equipment. For this, an auto-darkening helmet is essential to protect you from the light, heat, and spark generated from the welding process. Wear heavy-duty welding gloves. These will protect your hands from heat, electrical shock, and radiation.

Also wear a durable, non-flammable apron to protect your clothes from sparks coming out during the welding process.

Step 4:  Take The Preparation For The Process

Before starting the process, make sure everything is at hand and ready. Work in an open space with open doors or windows. Because the welding process will generate contaminated gases, which are hazardous to inhale.

Look at your welder machine before beginning. Inspect all the hoses, wires, and connections to the equipment. Replace any worn or damaged part before using.

Finally, make sure the metal pieces you have to work are secured in their respective places with the clamp. After you’ve put on gloves, the helmet, a welding apron (or a cotton work shirt), and work boots, you’re ready to start your desired welding process.

Step 5: Preparing The Metal For Welding

Before welding, scrape rust or any paint off the metal until it becomes metallic and shiny looking. The reason is rust and paint will inhibit the electrical connection produced by the welder. You can use an angle grinder, a wire brush or 80-grit sandpaper.

The metal you’ll work must be free from dirt, dust, and debris. To remove these contaminants, use acetone. Wipe down the entire surface of the metal with an acetone saturated cloth.

It’s also important to dry the metal with a clean rag to remove any of the acetone if left over any on the surface.

Step 6: Using The Multi-Process Welder

When you start welding, you should move as little as possible. You must use both your hands to hold the machine. Make sure that you’re going to do it right. It’s good to do a test run without switching on the machine. After being assured the tip of the welder/ torch is clean, connect the metals along the joint with tack welds. Once you’ve done, gently add the last weld beads while keeping the length of the arc consistent.

Some recommended projects for beginners are a pencil holder, a fire pit, a metal trellis, a doorbell and a flower made of metal spoons.

Hope, this guideline has provided you with the inspiration you required to start welding.
