What are you welding with?
at work i have a Lincoln Powertec i250, Europe Industirial version synergetic Perfect MIG welder for sheet metal up to heavy 1/4" + steel.
MIG is way easier to handle, less sensitive for rust, overhead welding. TIG means learn learn, perfect gaps, decreased and needs way more skills. I use a TIG from Stahlwerk at home.
Torch rod welding is easier than TIG, perfekt for bending, filling gaps, but always fire danger.
Laserwelding is the ultimate and expensive way to weld. Almost no heat imput to the material!
