Basics of Welding Processes

welding processes

First, let’s go over the basics of a few types of welding.

MIG welding uses a continuously-fed spool of wire and a MIG welding gun to weld together two pieces of metal. MIG is fairly simple to learn and very versatile.

It can be used for a wide range of metal thicknesses and allows you to weld a variety of materials such as mild steel, nickel, stainless steel, and aluminum.

However, MIG welding has a high heat input and is not an ideal process to use for vertical or overhead welds or use with lighter metal alloys due to the possibility of melt-throughs. In addition, it can’t be performed on rusty materials and dirty materials, or in windy or rainy weather.

The TIG welding process uses an electric torch with a tungsten electrode to deliver the current to the welding arc. A filler rod is hand-fed into the weld puddle, while the torch is held in the other hand.

Both are protected and cooled by inert argon gas. TIG Welding is particularly useful for difficult-to-weld positions like overhead welding and is used mostly with thinner, light metal alloys.

TIG welding is a more complex method to learn. A great deal of control and accuracy must be maintained in order to keep the arc the correct distance from the metal work pieces.

Stick Welding works through a single electrode that also provides most of the welding material. The electrode, again, gets heated then melts, but the intense heat melts the work piece and welds the two parts together.

The rod is also coated in flux cored, which creates a shield around the weld, protecting it from contamination. Stick tig welding creates exceptionally strong welds and can be used with very thick materials, even cast iron.

Additionally, stick welding can be used for welding in unfavorable conditions, like heavy rain or strong wind. However, the heat generated while welding makes this style unusable for welding of thin materials because you will simply burn through the sheets.

The style also requires more dedication and has a steeper learning curve, because it is quite difficult to strike an arc and not damage the material in the process.

Regardless of what you get, you'll want to make sure you are protected by having the right equipment. That includes the actual machine, clothing, as well as welding helmets or lenses.

Pros and Cons of Multi-process Welders - Buying Guide

multipurpose welders

While no one welding machine can allow any welding operator at any skill level to handle every type of welding job on any type of materials imaginable, a multi-purpose welder (also known as a 3-in-1) comes as close as you can get.

What is a multi process welder?

A multi process welder is a welder that can do ALL types of welding - MIG, TIG, stick, ARC, and plasma. They are premium machines that are perfect for a jack of all trades who doesn't need to specialize in one type.

The Advantages

The biggest advantage of a multi-purpose welder is its versatility.

It allows you to use the same welder as a powerful, industrial-grade welder that can handle heavy-duty welding jobs such as car frames, or a light-duty welder for welding around the house or hobby use.

It gives a much broader range of jobs you can perform across a variety of metal types.

The Disadvantages

Many multi-purpose welders are heavy, with some weighing in excess of 85 pounds.

For an industrial workshop machine, this isn’t that bad. But for a home welder, this might be a bit of a problem.

Some larger projects require a significant amount of repositioning of the machine to reach different angles. A heavy machine simply doesn’t give you the range of motion and reach you need to accomplish that. Its portability can be very limited.

Also, multi-purpose machines rarely excel at all three welding types. While they’ll usually be strong in one area, they tend to suffer a bit in other areas.

What To Look For In A Multipurpose Welder

Like any piece of equipment you purchase, you want to get the best value for your money and have a welding machine that will last.

When you are shopping around for a multipurpose welder, here are a few things to look for.

Make sure the multipurpose welding machine you are considering has enough amps of output power to handle the types of projects you will be using it to weld. A welding shop project will require much more output power than a home welder or hobbyist.

You probably also want a machine that’s easy to set up and requires a minimum of instructions to operate. A complicated piece of welding equipment will just mean hours of time climbing the learning curve and the possibility that things can go wrong.

best multipurpose welder

Look for set-and-go weld control. Having to make a lot of adjustments to the settings in the middle of trying to run a weld bead is difficult to manage and you could end up with a sloppy weld.

You need to decide the essential features that you absolutely must have in your multipurpose machine.

More than likely, MIG welding will be one of the 3-in-1 methods.

As such, you will want to make sure that the dealer or manufacturer offers a spool gun either as part of the welder or as an option to purchase separately in order to prevent wire feed jams.

Another really nice feature if you get a machine with stick welding is arc control to keep the electrode from jumping.Be cautious about where the machine is manufactured and the support and warranty that is offered.

If something on the machine goes wrong and you cannot get the part the machine needs at a parts shop, or there is not a location for that manufacturer or a dealer nearby or even in the US, you could end up paying a fortune in shipping fees to get the machine to the manufacturer in order to correct the defect.

Where Can I Use This Machine?

The MIG feature allows a welding operator to use this machine in a professional welding shop for industrial uses such as fixing farm equipment or working on car frames.

The TIG welding features allow the user to create aesthetically-pleasing fine, artistic welds. The thin rod and the outstanding precision of the weld make this welding type very useful for sculpture, making and welds on motorbikes and car shells.

The stick welding feature allows you to use this welding machine on heavy steel constructions, for heavy repairs and pipes, or on dirty or rusty materials.


Welders come in many grades and price points that range from cheap to big bucks. However, not all welders can be used for every welding job. You can, however, come very close by purchasing a 3-in-1 or multi-process welding machine.

For not much more than the price of a one-process machine, you can have the versatility of a machine that is capable of being an MIG welder, MIG gun, TIG and stick welder or TIG, stick and plasma cutting or some other combination. Seriously, they have all possible combinations  including mig tig stick.

Any of the multi-process machines we’ve reviewed here will get the job done so it really depends on your price threshold and the features you consider essential.
