Andy, or anyone else:

My manual says the recommended speed for .030 wire is 2 inches of wire per minute per ampere. The volt-amp curves give a good representation for the voltages relative to the position of the "V" knob, but there is no data for the "Wire Speed" knob. The specs say the loaded feed rate is from 20-600 IPM. Is the feed speed setting linear? Does one division equal 6 IPM? The question stems from where I think the maximum rating is achieved. I should be able to run 130 amps at a 10% duty cycle. If I set the voltage to max, and the wire speed to 44 (assuming this to equal 44 x 6 IPM= 264 IPM, or 132 amps) my wire stubs into the work. If I back off the speed to 35, I get a nice arc with the "breakfast food buzz" that is always described. But, with an amp-clamp on the power cord, I only read 17.5 amps. Book says rated max draw is 20 amps. Would someone confirm the wire speed knob settings? It would help this novice grately to know if he's using the welder correctly!
