Whom It’s For
TIG welding takes lots of practice, as it requires both hands as well as one foot. Compared with MIG or stick weld-ing, it’s a bit like going from driving an automatic to driving a stick shift. TIG welding is well suited for auto bodies, chassis/frame, aluminum oil pans, stainless exhaust, metal art, sheet metal, piping systems, motorcycles and bikes.
- $250 and up.
- Capable of greater precision than the other processes.
- Strong, high-quality welds.
- Nice-looking weld beads.
- Welds a large range of alloys.
- Parts must be very clean.
- High-quality machines are expensive.
- Requires lots of practice to become proficient.
- Much slower than MIG.
With a TIG setup, the electrode is a tungsten wire. The electrode is not the filler material, as it is with the other processes. The filler is typically a long handheld rod instead of a wire feed spool, and you control the amperage using a foot pedal.
