Have a Hobart Beta-Mig 170 Wire will not feed
First make sure the nozzle tip is free of any debris and the wire will slide easily. Lift the case and go to the wire feed unit. Loosen the pressure nob then lift up to release the pressure wheel. Make sure the bottom wheel ( should have two grooves, one for .35 wire and the other for 025 wire.) Make sure the Wire Feed Tip is also free and it allows the wire to pass through. Pass the wire through the feeder across the drive wheel and into the hose. Allow the pressure wheel to drop, then lift the pressure know to the upright position. Turn clockwise to put tension on the wheel. Make sure the gas is OFF, turn power on, depress trigger switch. This should allow the wheel to turn and feed the wire.
