Oh Boy these things are crap, had a couple of them into the workshop to fix and its really not worth it. As magicniner says you might get away with it but youre going to struggle I think. What sets these things apart from real welders is the duty cycle. According to the manual this has a duty cycle of 15% at 90 amps and 100% at omly 37 Amps which is really low. It will probably eventually do the job but you will be stitching rather than welding.
