I'm working on a new hood for my Marauder and will need to weld some 22 gauge pieces into the hood. I'm looking for any input on how to set up my PP256 to get the best results. I will have 4 types of joints. Butt welds, inside corner, outside corner and lap joints. In particular I'm wondering:
1) What size and type tungsten
2) What to use for filler material -- I've heard mig wire is good but I assume you would want uncoated?
3) Straight DC but how about using pulse? Any benifit?
Plus any other tips and tricks.
