Soft aluminum wire is prone to buckling, so using a larger diameter may help. Better yet, invest in a push-pull feeder. In such systems,
a torque motor at the wire spool steadily feeds the wire while a drive motor located in the gun precisely controls wire speed at the arc. This maintains
constant tension, so the wire feeds consistently, even when the cable is looped, and at distances up to 50 ft. The XR-Edge torque motor features a high and
a low torque setting, letting you adjust performance, respectively, for larger or smaller diameter wires.
