The Magnum 400XA guns are designed for use with gas-shielded solid and flux-cored wires. The two-piece ergonomically designed handle minimizes size, while the non-slip grooves provide maximum comfort and control. A metal and cloth reinforced rubber bellows located directly behind the gun handle provides excellent flexibility and decreases operator fatigue. These guns are factory installed with a Fast-Mate™ European style wire feeder connector. All Magnum fume extraction guns can be used with virtually any Lincoln or non-Lincoln semiautomatic wire feeder. The 400XA must be used with the appropriate adapter kit.
