400 A air-cooled MIG gun

The Tweco 415-3545 is a 400-amp air-cooled MIG gun built for flux-cored and MIG welding with aluminum, flux-cored or solid wire up to .035 inch. It runs a 60-percent duty cycle on CO2 shielding gas and uses a 15-foot cable with a Tweco-compatible rear connection. The straight handle and fixed 60-degree neck give a familiar feel for everyday shop work.

Best for CO2 flux-cored and solid-wire jobs

Welders running flux-cored or solid wire on CO2 at up to 400 amps will find the gun matches their process. It is not suited for applications that require water cooling, a rotatable neck, or wire diameters larger than .035 inch. Buyers needing a different rear-end fit or a higher duty cycle should look at other models.

Fixed 60-degree neck with 15 ft cable

The neck is fixed at 60 degrees and the cable measures 15 feet, so the gun’s reach and angle are set. Tip series 14 consumables are used throughout. Confirm that the fixed angle and cable length suit your booth layout before ordering.
