How to troubleshoot no pilot ignition on Victor ULTRA-CUT 100 when the neon indicator is lit?
- J
  Jennifer BeanAug 1, 2025
  If the neon indicator on the cap board lights up but there's no ignition in your Victor Welding System, several factors could be at play. Start by checking the pilot return wire at the torch head; ensure it's connected and not broken within the torch lead, and connect the wire or replace the leads if necessary. Ensure that the negative supply cable is correctly connected. Also, the coolant may have become conductive, so flush the system and replace the coolant. The high-frequency cap (C4 on the Cap PCB) might have open wires or be disconnected; reconnect or replace it. Lastly, check that the pilot return wire is securely connected in the arc starter, and connect the wire if it is loose.

  If the neon indicator on the cap board is not illuminated, it could be due to several reasons. First, check if there is a 120V supply and that the CB4 on the plasma rear panel hasn't tripped. Look for a shorted cable, a defective circuit breaker, or a shorted ignition module input. If the CB4 hasn't tripped, check if 120V is present. If it is, there might be an open control cable; if not, there's a fault in the plasma power supply. Another cause could be a shorted electronic ignition module, so replace the module. Also, ensure all fittings are tightened.

Why is my Victor ULTRA-CUT 100 Welding System behaving erratically (EMI Interference)?
- D
  Danielle SuttonAug 12, 2025
  Erratic system behavior (EMI interference) in your Victor Welding System can stem from a few key issues. Start by checking the torch lead shield and the F1 ground cable to ensure they are securely connected and tight. Also, verify that the cap board ground screw is tight and not missing. If those components are properly connected, the issue may be internal. In this case, it's best to replace the PCB.

Why is my Victor ULTRA-CUT 100 leaking coolant?
- W
  Wanda HendersonAug 19, 2025
  If you're experiencing coolant leaks in your Victor Welding System, the issue might be damaged or punctured coolant lines, so replace them. Another potential cause is reversed supply and return hoses; ensure you match the coolant connection colors to the arc starter fitting colors.

What to do if there is no coolant flow in my Victor Welding System?

  Emily GibsonAug 26, 2025
  If your Victor Welding System has no or insufficient coolant flow, it could be due to a blockage in the supply or return hoses; flush the system or replace the blocked hose. Another possible cause is a missing or loose ground connection; make or tighten connections to a good ground.
