Need More Help?
Stick Support
Troubleshooting stays secondary. Start with the machine package, then verify the leads, holder, remote, cooler, or TIG torch path.
TIG Support
Many inverter stick machines also run TIG. Use the torch path when the question is cups, collets, gas lenses, back caps, or cooling.
