I have been practicing vert. up at work for a test I have and none of the welds are turning out as nice as I would like. I am getting a large mound of weld right in the middle. I have tried going faster, wire speed slower/faster etc... but it still is there. I am using CO2, .045 solid wire, and ~23 volts and ~175ipm wire speed. Any ideas or hints?
