Mig and Tig Welders

For those of you who are new to welding, today’s blog will explain the differences between a MIG welder and a TIG welder. Both MIG welders and TIG welders are types of arc welders which use the concentrated heat of an electric arc to fuse metals together by a consumable electrode.

●     The Metal Inert Gas (MIG) weld process fuses the metal by heating with an arc. With MIG welds, the arc is placed between the filler metal electrode and the workpiece. Shielding is provided by outwardly supplied gas or gas mixtures.

●     A Tungsten Inert Gas (TIG) weld, on the other hand, functions by joining metals through the process of heating with tungsten electrodes that do not become part of the completed weld. The TIG weld process utilizes argon or other inert gas mixtures as shielding and filler metals are rarely used.

Most people in the welding industry would agree that MIG welders are faster to use, user-friendly, and are more affordable. However, MIG welding is also known for being a dirtier process and having a less reliable arc. Industry experts would generally agree that TIG welding is better because it is cleaner, more precise, and does not require a filler material, but TIG welders require more skill.

Everlast Welders has a large number of MIG and TIG welding products. We also have an equally large community of those who use our MIG welders and TIG welders, and they actively participate in our online forums:

●     For those of you who want to understand your MIG welders better, have questions, or would like some advice, click on the MIG Welding Forum.

●     For those of you who want to understand your TIG welders better, have questions, or need advice, click on the TIG Welding Forum.

To summarize, both MIG and TIG welders are great to use for welding, but they each have their advantages and disadvantages.
