Mig vs Tig concern

[eddie_ma70]

Hi everyone,

Long story short, want to do some rust repair on the bottom section for my Nissan, just wondering which welder should I get Mig or Tig, thanks!

Mig

Yep, probably MIG - better for welding "out of position" (i.e. upside down) - you can fill gaps easier and it's a bit beter on less than clean metal.

TIG - in my limited experience, is best for producing very neat welds on thin stuff, that is well fitted up and, for most of us mere mortals, can be put into positons easy to weld. And it'll cost you more for the equipment... (TIG)

HTH

MIG definately, heat input with TIG will be too high due to slow travel speeds and the material also needs to be "clinically" clean
