though visually everything has impressed me so far in terms of quality, the directions suck. it is a 165 amp DC inverter, digital readout, item 98233. is it lift or scratch? there is no indication. My background- proficient in MIG, flux, arc and gas, only TIG welded a couple times with a super high dollar machine in a class, not good at it, don't know much about it, bought this to learn. if its not obvious i have not tried it yet, waiting for my filler rods to come in the mail, i ask now because i dont want to wreck my tungstens if i dont have to. also, please do not make this a harbor freight bash session, there are plenty of other forums for that.
