Key specifications

Selecting the right option

Match the tip bore to the wire diameter exactly — an oversized bore causes arcing inside the tip, while undersized causes wire drag. Thread size (M5, M6, M8) must suit your torch model. For high-duty-cycle welding, consider extended-life or silver-alloy tips. Always keep a stock of at least two sizes — production welding eats tips faster than any other consumable.
