Lincoln K2655-4 550A Magnum PRO 550 Air Cooled Semi-Auto MIG Gun 0.035 - 1/8in Wire

Lincoln K2655-4 Magnum Pro 550 Series 25' MIG Gun is ideal for use with flux cored wire of 0.035 - 1/8" in diameter.

Semiautomatic air cooled gun is suitable for applications requiring current rating of 550 A and is designed for MIG pulsed/flux-cored arc welding. Gun features high quality copper and aircraft grade aluminum parts to ensure superior electrical contact and heat dissipation. Gun with Secure-Lock gun tube to resist rotational slipping has barrel-style handle to offer comfortable grip that reduces fatigue. Gun with 45 deg or 60 deg gun tube angle and 100% duty cycle includes larger tip diameter and mass that improves heat dissipation to increase the tip life. Gun with four trigger leads for fast field repair has patent-pending Anti-Seize tip and diffuser thread design to reduce tip and diffuser seizing. It is ideal for high amperage, high duty cycle applications where heat-resistance and fast serviceability are essential.
