Hey guys , I have a 205s that is having problems with the 4T setting. It seems to work fine on 2t but when I switch to 4t the arc will start fine and go out as soon as I release the switch. If I turn on the upslope it will continue to weld for the number of seconds the upslope is set for and then go out again. it doesn't seem to matter what I have the start / end amps set at. I have adjusted the points gap to .035 and done a brief visual inspection of the internals. it seems to consistently go out as soon as it would switch from start amps to the main setting and there is no indication of any amps at that point ( I can touch the tungsten to the workpiece with no arcing , sticking , sparks or otherwise. any ideas?
