What welding processes do I need my welder to perform?
This is probably the most commonly asked question among beginner welders, and it is often the subject of confusion. But don’t be daunted when trying to to decide whether you need, TIG function, MIG function, MMA function or all three.
Welding is a complex skill but the following information will give you a basic overview in the main welding processes. Keep this information in mind when making your choice but If you require more detailed advice after reading this information, don’t hesitate to give us a call and we can assist further with advice in choosing your welder. It is important to note, that no one welding process is perfect for all welding applications, so if you’re looking to perform a versatile range of applications, you may wish to purchase a multi-purpose welder, capable of performing MIG, TIG and MMA function.Click here to view our multi-purpose range.
Here is a basic guide to the three main welding process (MIG, TIG and MMA):
MMA (Stick/Arc) Welding
MMA welders use an electric current flowing from a gap between the metal and the welding stick, also known as an arc-welding electrode. This form of welding is great for welding most alloys or joints. It can be used indoors and outdoors and is a good choice if you plan to weld in potentially windy conditions. It is effective on rusty and dirty metals.
A key to Stick welding is learning to strike and maintain an arc. This can be a challenge but once mastered it is a very effective form of welding on many metals. It is generally suitable for welding metals no thinner than 1.02mm (18-gauge). Welds should be cleaned upon completion. It is an economical form of welding and is is great for welding thicker metals of 6mm or more. They are a good choice for farmers, hobbyists and home maintenance chores.
Key MMA welding points
- Great for windy conditions
- Effective on thicker metals
- Effective for welding dirty or rusty metals
-Good for general DIY jobs, home maintenance and farmers

TIG welding is an arc welding process. It uses a non-consumable Tungsten Electrode to produce the weld. This weld area is protected from contamination by a shielding gas, along with a filler metal. TIG is an extremely precise form of welding and gives the welders great control and stronger welds than other processes.
It is most commonly used to weld thin sections metals, including alloy steel, and stainless steel, because of the precision it gives the welder. It is also an ideal process for non-ferrous metals such as aluminum, magnesium, and copper alloys. It is a more complex form of welding and will require more time to master. But once you’ve got the hang of TIG welding it is a brilliant process.
Key TIG welding points
- Extremely precise, and produces strong welds
- Precise results on thin metals.
- Ideal for allow steel, stainless steel, aluminum, magnesium, copper alloys.

MIG welders use a wire welding electrode on a spool. The spool is fed automatically at a constant pre-selected speed. The arc, created by an electrical current between the base metal and the wire, melts the wire and joins it together with your base metal.
MIG welding is clean, and it is great for thin and thicker metals. It is easy to master as long as you don’t rush in without doing your research. MIG welding is effective on a wide range of metals including steel, aluminum and stainless steel. It is effective on metals as thin as 0.4mm
Key MIG welding points
- Easy process to master Very clean welds
- Effective on a wide range of metals including steel, aluminum and stainless steel
- Great process for welding thin metals with precision
