I have a 2018 model AHP Alpha 200X tig welder. This past week when using TIG it seems to lose power after starting. I've read of issues with the high freq contacts causing it not to start; but that's not my problem. In fact my issue is the opposite, it starts fine, welds 1-2 seconds and then the power drops from the weld setting (135 to 160 amps) to 27amps. My helper noted that every time it dropped it went to 27 amps. Sometimes it welds for 5-10 seconds before dropping but usually within a second or two of arc start.My first thought was perhaps a duty cycle issue; but that dosen't seem to be the case since it starts fine and the issue works from a cold start. All connections & grounds have been checked. I usually use the foot pedal, but swapped that out for the finger control and the issue persists. Any ideas would be appreciated.
Reply:Is 27 the lowest it is capable of going or can it go lower?
Reply:A few things you need to check. Make sure you are it 2T, pulse is off (switch all the way down) start amps and end amps are off.www.georgesplasmacuttershop.comPlasma Cutter and Welder Sales and Repairs--Ebay storeTec.Mo. Dealer Consumables for the PT and IPT torch's
