What to check first

Service-counter sequence

Torch overheating

Verify cooling system on water-cooled setups. Inspect torch cable and handle heat. Check amperage against torch class. Verify front-end consumable fitment.

Service-counter sequence

Unstable arc

Inspect tungsten contamination first. Verify collet tightness. Inspect cup or gas lens seating. Verify shielding gas flow.

Service-counter sequence

Poor gas coverage

Inspect cup condition. Verify gas lens seating. Check flow rate. Inspect hose or fitting leaks.
