Additional Features

Ultra portable and versatile - The slim ergonomic design of the XR-Aluma-Pro torch allows access into the tightest of quarters. Coupled with the XR-AlumaFeed feeder and the AlumaPower 350 MPa or 450 MPa synergic power supply, it has the features for all of your aluminum fabrication needs.

Synergic pulsed welding mode offers the simplicity of single-knob control. The machine will select the correct pulse power based on the wire feed speed (WFS) set by the operator.

Profile Pulse - Achieve “stacked dime” weld bead appearance without back-stepping.

Parameter and system locks provide three levels of protection to prevent accidental modification of welding parameters or manipulation of setup menu items.

Synchronized, true push-pull wire feed system - Slave/torque motor ensures smooth, consistent feeding and improved arc performance, while reducing the problems normally associated with feeding aluminum.

Standard integrated flowmeter which helps to regulate gas flow rate. This helps ensure weld quality when working over long distances.

Gun bushing.
Improved gun connection uses a bushing that captures the power end of gun to ensure correct alignment to drive rolls and provides exceptional ruggedness and durability.

Drive assembly.
Improved drive assembly with numeric scale for different wire sizes prevents wire slippage and deformation. Helps improve wire feeding by ensuring that the proper drive-roll tension is used. Comes factory-installed with 3/64-inch drive rolls.

Synergic “one-knob” control.
Set the wire feed speed control on the gun and the Alumafeed system handles the rest, simplifying set-up and reducing training time. No need to travel back to the power source to change multiple parameters.
