Just as there are a variety of different workpieces created by arc welders, there are also a variety of different arc welding processes. Making the choice of which is right for a project is vital if you want to have success. Although there are similarities between TIG and MIG welders, the techniques are very different and if you use the wrong one on the wrong project, you are only going to give yourself headaches. Below, we are going to highlight some of the main reasons why you consider investing in a MIG welder.
First, let’s understand what makes them different from one another. They both use electric arcs to create welds. However, the difference is how you actually use the arc. While MIG or Metal Inert Gas welders use its feed wire continuously as it moves in and out of the gun to make the spark, then starts to melt and create the weld. TIG or Tungsten Inert Gas welders utilise longer rods to fuse together two metals directly.
Easy to Use
First things first, it is important to note just how easy MIG welders are to use compared to TIG welders. In fact, you can actually learn and finetune your skills to precision within a few short weeks. Many even see it like a hot glue gun style of welding – you simply pull on the trigger to both start and stop welding. You only need to hold a MIG welder with one hand, which makes it great for beginners. Whereas with TIG welders require a more specialised technique that involves the use of one foot and both hands all doing different things.
When it comes to manufacturing, time always means money. As MIG welding is a much faster process from start to finish than TIG welding, it is, therefore, more cost-effective. There is also the fact that MIG welding parts are far easier to source than TIG welding parts, which also reduces the cost.
MIG welding guns are built to run constantly over a longer period and as they are faster to use than the alternative, as pointed out above, they are more productive and efficient. MIG is the number one choice with larger industrial operations due to the fact it has higher production rates.
Diverse and Versatile
Last but not least, one of the reasons why so many people opt for MIG welders over TIG welders is the diversity and versatility they provide. Although you can use TIG welders with a greater number of different metals, they are less effective when working with thicker materials. MIG welders are effective with steel, stainless steel and aluminium and with a range of thicknesses from 26-gauge sheets of metal to more heavy-duty plates.
One of the biggest advantages MIG welding has over TIG welding is that its wire feed functions as the filler and electrode. Because of this, thicker parts can be easily fused together without heating them fully. Also, as it relies on filler instead of fusing, you can actually weld two materials together.
