Machine families to check
Verify machine package
This torch path is catalog-listed, but machine compatibility should be confirmed from the machine package before ordering.
What to check first
Unstable arc
Inspect tungsten contamination first. Verify collet tightness. Inspect cup or gas lens seating. Verify shielding gas flow.
Poor gas coverage
Inspect cup condition. Verify gas lens seating. Check flow rate. Inspect hose or fitting leaks.
Tungsten splitting
Verify polarity. Verify amperage. Inspect shielding gas coverage. Confirm tungsten type and diameter.
