Use the breakdown
Match the diagram number, tungsten diameter, cup size, and gas lens or standard setup before ordering.
Then choose consumables
Cups, collets, gas lenses, collet bodies, back caps, and tungsten are series-specific.
Breakdown pending
This torch family does not have a dedicated diagram on the page yet. Use the torch series and machine package to confirm parts 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.
