Best Multi-process Welder Buying Guide- Shopping Secrets
Buying an all in one welder is not an easy task as there are many to choose from and purchasing the best multifunction welder online may seem like an impossible task, but don't worry! We can let you in on a few trade secrets to help you in find the best one for your needs.
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 the welding machine you need to get your job done. In general, the MIG welding process will be one of them. The most common combination of multi-process welding machines is MIG, TIG and stick welding. This will cover a large variety of projects. It’s also convenient having a 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 a 3 in one welder or a 4 in 1 welder to use for alloy, steel, stainless steel and even aluminum.Some common popular combinations in this category are:
PLASMA CUTTING OPTION: Is it essential?
If you find a product that features the combination of TIG/ MIG/ Stick welding processes, you can add it to your buying list. This combination will cover a wide range of the welding processes for your projects at the DIY level. In addition to these welding processes, it’s a good idea to pick 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 thinking to buy can provide enough output power to tackle your projects.
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 with at least 150 amp power. If you use it regularly or use it for your automobile repairs, then a machine with 200-300 amp will provide you with sufficient amps of output to tackle the types of materials you’ll be using. You should always consider the types and thickness of metals that you’ll be working with when deciding which unit to buy.
AC & DC CAPABILITY: Which power supply is important for welding?
Power supply is another factor to consider when welding. It’s important to determine which type of power supply the unit requires, and which type you have 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 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 materials like steel, you’ll need a direct current. A unit with AC capability will work better on self-oxidizing metals such as aluminum or magnesium.
USER-FRIENDLY INTERFACE: Is it essential?
A complicated welding machine will mean that you will spend more time making adjustments to the settings. If you're in the middle of a process to run a welding bead, it's hard to manage a change in settings without a good interface.
Choosing a model that's easy to setup and adjust, easy to use and learn to use is important. This means choosing a machine with a user friendly interface and control, making it more convenient and easier to use.
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 around frequently, you should go for a compact and portable multi-process welding machine which can be moved and transported easily. In comparison, a heavy device won’t be practical as you can’t move it around freely 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. Most multi-process welding machines are cheaper than purchasing the different units for different processes.
You need to figure out what it is you want from the equipment. Cheaper welders are more than sufficient for basic jobs, whereas the more powerful units will have premium features.
If you have the money, a more expensive option will offer more power and better features.
Don’t rush into buying a machine without taking some time to define your needs and budget. If you're not sure or something is unclear, we’re here to answer any questions you have about welding processes, machine operation, benefits, and limitations. When you’re ready to match a specific model with a task, hobby or business — we can suggest the product or model that is suitable for your needs.
Benefits Of Using Multi-Process Welding Machines
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 task.
In general, a multi-process welder offers TIG, Stick, MIG and flux-cored welding processes. 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 their versatility, convenience, space/portability, and the price.
- Versatility: A single process unit never offers the versatility that the professional or even a DIY user typically requires. The most significant benefit of using a multi-process welder is its versatility. Multi-process welders allow the user to use the same machine for various welding processes, letting them perform a wide range of tasks across a variety of metal types.
- Convenience: This equipment makes it easier for users to tackle several tasks on a construction site or DIY/ home project. A multi-purpose machine can be easily adjusted to suit a user’s specific needs. Without having to switch power switches or machines, the user can finish their tasks quickly. Amateurs and professionals both appreciate easy to use controls as well as quick response when shifting from one process to another.
- Price: Although some multi-purpose welding machines seem expensive, if you actually bought each of the individual processes as a seperate item, the total cost of all the machines would far outweigh the cost of a multifunction welder.
- Space/ portability: Having to store and transport three or more different types of machines for different processes requires a lot of effort and space. Doesn't having a single compact sized unit seem much more appealing?! Storing and transporting a single unit definitely makes your life a lot easier.
Limitations Of Using Multi Purpose Welders
Although multi-process welders have a number of advantages, these units are by no means perfect.
We have tested various types of multi-process welders, and the most common issue that we’ve come across is the weight of the machine. Some multi-process machines are more than 85 pounds. If you are using your multi-process welder for industrial purposes, you may need to reposition the machine to reach different angles if you are working on a large project. A heavier unit may be more difficult to handle and move, limiting its portability.If you are more typically a home user, the weight of a multi-purpose welder could also be annoying when you need to move it around.
Common Mistakes When Purchasing All In One Welding Machines
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 basic welds you don’t need to go for feature-rich welding machines, which add significantly to the cost. To meet your basic operational needs, a unit with primary features will do fine. For example, if you don’t need to weld magnesium or aluminum, there's no need to purchase a unit with AC capabilities. So before choosing a model, consider what materials you will be working with.
- Inappropriate input voltage: It’s essential to understand what your power capabilities are. Some units are compatible with both 110volt and 220volt and the output at 110volt will be significantly less than at 220volt. There are also single phase multi process welders and three phase welders. Before buying a unit, make sure to check the input power or voltage so that it matches up with your available power.
- Cooling option: The larger unit may require a separate cooling tool to achieve the full output power from the welding machine. This will add to the cost, so make sure the unit that you decide to buy has its own cooling option or you will 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.
How To Use a Multi Process Welding Machine - Step By Step Instructions For Beginners
Welding is an art. It’s a delicate art that will initially require patience and practice to perfect. However, once you have learned how to weld and how to use a multi-process welding machine, you can make anything - steel will be like a blank canvas for you.
The following guidelines will help you to learn the basics about welding.
Step 1: Decide On The Welding Process
Choose the appropriate welding process for your project. MIG is one of the most precise and popular welding processes and also the most straightforward to learn. Other popular operations include stick welding (SMAW) and flux-cored arc welding (FCAW).
Step 2: Put Together Your Welding Kit
Next, you'll need to arrange your equipment to create a welding kit. A welding machine is the first piece of equipment and also the most essential so invest wisely.
We recommend the Lincoln MIG 210 MP Electric POWER TIG One-Pak - K4195-2 Multi-Process Welder, a great option for beginners.
You’ll also need a chipping hammer, some miter clamps, a pair of welding pliers, an angle grinder, shielding gas and some welding wire. A welding cart is an excellent addition so you can move your welding machine around.
Step 3: Stay Safe
Now for the protective equipment. An auto-darkening helmet is essential to protect you from the light, heat, and sparks generated from the welding process. Wear heavy-duty welding gloves to protect your hands from heat, electrical shock, and radiation.
A durable, non-flammable apron is also highly advised to protect your clothes from sparks during the welding process.
Step 4: Preparing For The Process
Prior to starting the process, ensure everything is at hand. Work in an open space that's well ventilated as the welding process will generate gases which should not be inhaled.
Next step is to inspect your welding machine to ensure that everything is as it should be and in working condition. This includes inspecting all the hoses, wires, and connections to the equipment. Replace any worn or damaged parts before using.
Finally, ensure the metal pieces you are working on are secured in their respective places with clamps. Put on your gloves, helmet, welding apron and work boots, and you are now ready to start your welding process!
Step 5: Preparing The Metal For Welding
Before welding, scrape any rust or paint off the metal until it becomes metallic and shiny looking as rust and paint inhibit the electrical connections produced by the welder. You can use an angle grinder, a wire brush or 80-grit sandpaper to help in removing it from the metal.
The metal should also be free from dirt, dust, and debris - you can use acetone to wipe down the entire surface of the metal.
It’s also important to dry the metal with a clean rag to remove any residual acetone on the surface.
Step 6: Using The Multi-Process Welder
Once you've started welding, you should limit your movements. It's best to use both hands to hold the machine in place and it’s also beneficial to do a test run without switching on the machine. Once you have checked the tip of the welder/ torch is clean, connect the metals along the joint with tack welds. Then gently add the last weld beads while keeping the length of the arc consistent.
Some recommended projects for beginners to practice on are pencil holders, a fire pit, a metal trellis, a doorbell or a flower made of metal spoons.
So, which of these multi process welding machines is the best?
Choosing any of the above multi process welders will give you an economical, durable and practical way to get the job done.
When we tested and reviewed all the products, we noticed that some are more affordable and others are higher-priced, but all are versatile, functional and user-friendly. That made it tough to choose an overall winner.
