Welding Tips and Tricks

need to identify welder
I need to know if this is auto sensing for 110/220 as it has an after market plug on it also with 110 this seems to have very high ratings for amps.
It has a clean function?? gas valve does not open with this feature?? and arc is very weak.
(NOT ACDC for aluminum???)
I want to add a foot and a finger tip control to this !

the plug on the front I assume is torch on/off and wonder if the one on the back is for the plasma cutter?

any and all operating tips or stats on this will be appreciated

ive never seen that type of welder before...sorry

Definately some kind of chinese welder :p I'd assume you already checked for some kind of nameplate/phonenumber on the bottom or something. That looks like a computer case fan on the back of that thing.

As for the aftermarket plug, someone could have just bought a 220 welder, decided they didnt have/want a 220 outlet, and cut the cord and put a 110 plug on it to try and weld on a 110 circuit. I'd wager thats why your arc is so weak.

If it was me I'd talk to whoever you got it from and ask em WTF?
