Durable, Comfortable Handle

Superior Wire-Feeding

Wire delivery is optimized because the front-loading AccuLock liner is locked and concentrically aligned with the contact tip and power pin. Reduces downtime and troubleshooting.

Error-Proof Liner Trimming

No measuring required! Simplifies maintenance and prevents downtime and issues caused by improperly trimmed liners.

Long-Life Consumables

Tapered mating surfaces between the AccuLock contact tip and diffuser locks the tip in place for maximized electrical conductivity and lower heat.
