- CCheyenne BrooksSep 4, 2025
Poor quality welds with your Pro Spot Welding System can be caused by: * A clogged nozzle. Clean or replace the nozzle. * Holding the torch too far from the workpiece. Hold the torch at the right distance. * Insufficient gas at the weld area. Check that the gas is not being blown away by drafts and if so move to more sheltered weld area. If not check gas cylinder contents gauge, regulator setting and operation of gas valve. * A rusty, painted, damp, oily, or greasy workpiece. Ensure the workpiece is clean and dry. * Rusty or dirty wire. Ensure the wire is clean and dry. * Poor ground contact. Check the ground clamp/workpiece connection. * Incorrect gas / wire combination. Check on the manual for the correct combination.
