What to check first
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.
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.
Verify torch series before ordering
TIG front-end parts are not universal. Match the torch series, tungsten diameter, gas lens or standard setup, and cooling requirement before ordering. Amazon links remain optional buying references only and are not used as compatibility truth.
