For some reason weld looks a little cold compared to the results i had with the 185, I did not have any problems on 1/2" x 2" cold rolled flat with no preheat. Here is a picture of a flange bending tool i made just before you purchased my welder. This was used on 240 volts 160 amps 15 cfm or 7 lpm, WP 17 torch 3/32 ER70S2 filler
Just wondering if you are operating on 110 volts ??.
