Question about Welding Tools
I have a plasma cutter that just stopped working.has HF arc in tig and plasma but nothing else. I pulled out all the boards to check for burned areas,thought i had all the wire connectors marked down on paper the right way but guess i might not have.Looking for the connector schematic to hook up right.Anyone out there got any idea where i can get it? Thanks

Be sure you have the ground is connected to the postive terminal on the bottom of the front of the machine. Air pressure should be 70psi as the air flows out of the torch.

If those are the power input, then the green is the grounding wire (safety ground).
If the unit is 220/240 volt, then the blue AND brown are the hot wires.
Neutral would not be used in this case.
If the unit is 120 volt, then the blue is the hot and the brown is the neutral, but your unit probably requires the 240 volt. Check the owners manual and label on the unit.

Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.

They probably suspect board damage in the gas control / air control. They will analyze the pictures, looking or signs of failure. If found, they will either send you a new unit, or replacement boards to be installed. This is very common troubleshooting / diagnostic when the manufacturer gives its support staff the training and latitude to go this deep.
Give it more time, you are easily within the warranty period. Keep track of all communications though. Given that you just bought the machine, I am surprised that they were not more apt to replace it altogether unless another is not available.

check first the pilot arc, if air pressure is there or not.next check solanoid valve working or not
