    I got this machine about 4 weeks ago. Been having an intermittent problem. Occasionally it will weld fine, then I turn it off and prepare for another weld. When I turn it back on, it won’t start an arc. I shut it off and then the next day it starts up just fine.

    Tonight I noticed that the power light was not on even though the machine was on, the light on the switch was on, the fan was on, when I tapped the pedal gas would flow, but no arc. I had just welded a section maybe 20 minutes earlier.

    Anybody have an idea to help? I reground the tungsten to rule that out and checked the ground again.
