  If your Hobart Welding Products Welding System exhibits these symptoms, ensure the Voltage switch is set to positions 1, 2, 3, or 4. Verify that the gun trigger switch is depressed and held. Check if the Over Temperature Light PL1 is on, and if so, allow the unit to cool until the light goes off. Make sure the Voltage switch is not set between ranges. Finally, disassemble the torch handle and check the trigger switch lead connections, tightening or reconnecting any loose connections.

  If your Hobart Welding Products Welding System has low weld output, connect the unit to the proper input voltage or check for low line voltage. Place the voltage switch in the desired position. Check the cable connection at the work clamp and tighten the hardware if necessary. If using an extension cord, check that the wire size and length are the proper size for the power rating of the welding power source.

  If the electrode wire feeding stops during welding with your Hobart Welding Products Welding System, first ensure the wire spool is not out of welding wire. Readjust the hub tension and adjust the drive roll pressure. Check the supplementary protector CB1 and reset if open. Also, check if the Over Temperature Light PL1 is on, and if so, allow the unit to cool until the light goes off. Straighten the gun cable or replace damaged parts. Change to the proper drive roll groove and replace the contact tip if blocked. Clean or replace the wire inlet guide or liner if dirty or plugged. Replace the drive roll or pressure bearing if worn or slipping. Finally, check and clear any restrictions at the drive assembly and liner.
