What to do if MAC TOOLS MW135 has no weld output, wire does not feed, and the fan does not run?
First, ensure the power cord is securely plugged into the receptacle. Then, check the building line fuse and replace it or reset the circuit breaker if it's open. Make sure the power switch is in the On position. Finally, for CSA models, check the circuit breaker CB and reset it if needed.
Why is there low weld output on my MAC TOOLS Welding System?
The low weld output might be caused by incorrect input voltage. Connect the unit to the proper input voltage or check for low line voltage. Also, ensure the voltage switch is in the desired position.
What to do if MAC TOOLS MW135 Welding System electrode wire feeding stops during welding?
If the electrode wire feeding stops during welding, try the following: * Straighten the gun cable or replace any damaged parts. * Adjust the drive roll pressure. * Change to the proper drive roll groove. * Readjust the hub tension. * Replace the contact tip if it is blocked. * Clean or replace the wire inlet guide or liner if it is dirty or plugged. * Replace the drive roll or pressure bearing if it is worn or slipping. * Secure the gun trigger leads or repair them. * Check the circuit breaker CB or CB2 and reset if necessary. * Check and clear any restrictions at the drive assembly and liner.
What to do if MAC TOOLS MW135 has no weld output but wire feeds?
If there is no weld output but the wire feeds, ensure the work clamp has good metal-to-metal contact. Replace the contact tip. Also, check for proper polarity connections.
