Welding Tips and Tricks

this is the machine that i used to weld aluminum.

You can't use that machine for welding aluminium (very easily) as it is a DC mig/stick /tig. For learners and basic stuff you need an Ac/dc tig welder.

hi mate,if cant use the machine to weld aluminum,can i use it for steel welding?

ok thanks mate,if i can use for steel this machine.can i use it also for stainless steel mate? i would be happy if i can use this machine

its fine with stainless.

for car exhaust mate what kind of stainless this one? is this machine is ok for welding stainless forexhaust.pls see attachment thanks

Yep mate, steel, stainless steel and any other material that states DC electrode positive for welding. Aluminium requires AC cutting, the constant change of polarity is used to break down the aluminium oxide layer.

ok mate thanks a lot for this one,,uve been helpful to me.ill try this machine to weld stainless steel.

If you tig the stainless, you'll probably have a better outcome with DC electrode negative, though...

His statement was and steel can be TIG welded, plus the OP can weld anything set for DCEP. All DC TIG is set for DCEN, but the machine can also do DCEP.

Damn. Sorry fellas. DC electrode Negative is it. Need to proof read better.
