ok ive a migatronic, welds a1, no questions, and welds very very nice on car bodywork, but? im tempted by these r tech migs, but there only go two 30 amps min, i wouldnt change from the migatronic, but r tech is smaller and lighter, , seems some on here have upgraded to r tech from crappy seally, clarke welders, so theres going to be a big diff,, no offence to there owners,, the cars ive welded are mostly 0.8mm thick steel, andbody have pics and or advice cheers guys
