OVERVIEW

Stop Birdnesting and Start Welding

If you weld aluminum, you know the frustration of a birdnest. The wire stops, the burnback happens, and you lose twenty minutes clearing the liner. The Miller XR-Pistol Plus Water-Cooled MIG Gun is the answer to those headaches. Designed specifically for the softest aluminum wires, this push-pull gun grabs the wire at the handle and pulls it through, working with your feeder to deliver a smooth, steady stream of wire exactly where you need it. No more stuttering, no more tangles.

This model (300758) is the heavy hitter of the lineup. It is water-cooled and rated for 400 Amps at 100% duty cycle. That means you can run hot and fast all day long without the gun overheating in your hand. The water cooling keeps the front-end consumables lasting longer and keeps the handle cool to the touch, even when you are pushing the machine to its limits. Plus, with a massive 35-foot cable, you can walk around the entire boat, trailer, or tank you are welding without having to drag the heavy feeder with you.

Comfort is king when you are under the hood for eight hours. The pistol-grip design is balanced to reduce wrist strain, and the trigger hold feature lets you relax your finger during those long, continuous welds. Need to weld overhead or in a tight corner? The front tube rotates 360 degrees, so you can position the nozzle perfectly without contorting your arm. It uses the standard Miller tips you likely already have in the shop, making it easy to keep running. Upgrade your aluminum game with the reliability and reach of the XR-Pistol Plus.

FAQ

The XR-Pistol Plus Water-Cooled is rated at 400 Amps at 100% duty cycle using 100% Argon gas.

It is designed to feed aluminum wire sizes from .030 inch (0.8 mm) to 1/16 inch (1.6 mm).

Yes, it is a push-pull gun that typically requires a Miller XR-AlumaFeed, XR-S Control, or XR-D Control to operate the push-pull motor synchronization.

No, this specific SKU (300758) comes with a fixed 35-foot (10.6 m) cable assembly.

It is compatible with Miller FasTip and Centerfire contact tips and nozzles.

Water-cooled guns are lighter (at the handle), run cooler for the operator, and have higher duty cycles for continuous high-amperage welding compared to air-cooled models.

While mechanically possible, push-pull guns are expensive and specifically engineered for soft wires like aluminum. Using them for steel is generally unnecessary and causes premature wear.

Yes, it features a trigger hold (lock) to reduce fatigue during long welds.
