I looked at cheap migs a while back. I just could not turn down a $40 deal thinking I could use it to do some quick fixes to exhaust hangers and so forth. The tig attachment for this unit may cost more than the unit so not planning to go down that route.

Does that unit accept gas? if not the tig welds will need excessive heat for it to fuse/melt together and will be very porous. I failed my welding tech cert 2x due to porosity - gas pressure too low the first time and lack of penetration - heat too low the second. Luckily third time was a charm.

I find myself gravitating to the mig for most mild steel and the tig for stainless and aluminum.
