I think your problem is that the machine doesn't allow fine enough adjustments to get the perfect looking weld. Once you get the settings just right, the weld will look great and be strong. Switches (high, low voltage) just won't do that. You could grind the weld a bit if it looks real ugly, and then paint it. |
I was mainly going by the chart on the front of the welder. It has 2 switches, One for Min and Max, the other for range 1 or 2. The settings go min 1, min 2, max 1, max 2. The chart shows a voltage increase for each step, but also an increase in available current. The change in available current seemed to be the more significant change on the chart, so that's what I thought I was changing. The voltage change is rather slight. From Min1 to Min2 the voltage only goes from 16 to 18 volts, but the current goes from around 20 amps to around 40 amps. (If I remember right the current steps are 20, 40, 65, 110).
