What to do if electrode wire feeding stops during welding with Miller MILLERMATIC 175 Welding System?
- V
  vperryAug 8, 2025
  If the electrode wire feeding stops during welding with your Miller Welding System, there are several potential solutions: * Ensure the gun cable is straight, and replace any damaged parts. * Adjust the drive roll pressure. * Change to the correct drive roll groove. * Readjust the hub tension. * Replace a blocked contact tip (an oversized tip might be needed for certain wires). * Clean or replace a dirty or plugged wire inlet guide or liner. * Replace worn or slipping drive rolls or pressure bearings. * Secure or repair the gun trigger leads. * Check for and clear any restrictions at the drive assembly and liner. * Release the gun trigger to allow the gun and motor protection circuitry to reset. * Have a Factory Authorized Service Agent inspect the drive motor.

Why Miller MILLERMATIC 175 has no weld output, wire doesn't feed, but fan motor runs?
- G
  Gregory GreeneAug 15, 2025
  If your Miller Welding System has no weld output, the wire doesn't feed, but the fan motor still runs, it could be due to a couple of reasons. First, the thermostat TP1 might be open due to overheating. To resolve this, let the fan run with the gun trigger switch off until the unit cools down and the thermostat closes. Second, ensure the gun trigger leads are securely connected.

  If your Miller Welding System has no weld output and the wire feeds, ensure the work clamp is connected for good metal-to-metal contact. Also, replace the contact tip, check for proper polarity connections, and tighten the thumbscrew securing the gun end to the feed head adapter.

How to troubleshoot Miller MILLERMATIC 175 Welding System with no weld output, wire feed, and fan?
- D
  Damon BlakeAug 27, 2025
  If your Miller Welding System has no weld output, the wire doesn't feed, and the fan doesn't run, check the following: ensure the power cord is securely plugged into the receptacle, replace the building line fuse or reset the circuit breaker if it's open, make sure the power switch is in the On position, and reset the welding power source circuit breaker if it's open.
