•Unique drive roll design provides positive feeding and quick reloading by simply starting wire into guide tube. The drive rolls and guide tubes are designed for long life and precise wire feeding.
•
•Completely enclosed case protects the heavy duty wire drive mechanism from damage, but allows easy access to drive rolls.
•Control circuit features “cold electrode” when the gun trigger is released for an added measure of safety.
•Low voltage (24 volts) gun trigger circuit.
•Dynamic braking system stops wire feed motor quickly to minimize crater sticking problems.
