Looking for a bit of help. Just picked up a used Lincoln Square Wave 355. Finally got it all wired up and set up. But the unit will not generate an arc. Amp display is working, set it to around 200 amps. HF start is working (can see the ionizing arc but doesn't establish the welding arc) , gas valve is working as well, just not getting an arc started.
I did switch over to stick mode from tig and nothing there either. Looked at the troubleshooting in the manual and the only thing I could determine is there is no Open Circuit Voltage. I'm showing around 0 to 2 volts on the meter when the amptrol is depressed, when turned from full CCW to full CW. On a side note the amp meter shows only 410 while in stick mode can not change this value with the amp knob.
Any assistance would be greatly appreciate on what might be wrong even if it's operator error.
