Infinite voltage control with wire feed speed tracking provides broader operating range with finer control by automatically increasing or decreasing wire feed speed when voltage is adjusted.

Durable cast aluminum feedhead incorporates dual groove quick-change drive roll and calibrated, spring-loaded tension arm designed to make setup easier and faster.

Easy access to output studs provides convenient polarity changeover when switching from solid or flux cored wires.

"Tip Saver" short circuit protection shuts down output when tip is shorted to the work. Extends contact tip life and protects internal components from damage. Trigger reset permits quick reset at torch rather than unit.

Built-in solid-state contactor circuit makes wire electrically "cold" until trigger is pulled. Makes unit safer, and is easier to position torch to work before starting to weld.

Thermal Overload Protection
Internal components are protected from damage by thermal overload protection which automatically shuts down the unit if duty cycle is exceeded or air flow and cooling are restricted.
