Why is there no gas flow when I depress the MIG torch trigger switch on my Infinium WELD STAR WS-MU4-1?
- B
  Barbara CabreraAug 17, 2025
  The absence of gas flow could stem from several reasons. First, the gas cylinder might be empty, requiring a replacement. Second, the gas regulator could be turned off, so ensure it is on. Third, the gas hose could be blocked or cut, necessitating a check, repair, or replacement. Lastly, the torch trigger switch lead may be disconnected or faulty, requiring reconnection or replacement.

What to do if the digital display is OFF and the fan is not functioning on my Infinium WELD STAR WS-MU4-1?
- K
  Karen LongAug 20, 2025
  If the digital display is off and the fan isn't working, it might be due to a few reasons. The primary supply voltage may not be switched on, or the input fuse may have blown; in this case, switch on the primary supply voltage or replace the blown fuse. Another possibility is that the welding power source input switch is off, so switch it on. Finally, there could be loose internal connections; check and secure these connections.

Why does wire continue to feed through when the MIG torch switch is released on my Infinium WELD STAR WS-MU4-1?
- S
  sarahrichAug 26, 2025
  If the wire continues to feed through after releasing the MIG torch switch, the trigger mode switch might be set to 4T instead of 2T. Change the trigger mode switch to 2T. Another cause may be a faulty MIG torch switch, which would need to be replaced.

Why does the output current reduce when welding with my Infinium Welding System?
- D
  Dominique SchmidtAug 28, 2025
  A reduction in output current during welding could be due to a poor work lead connection to the workpiece. To resolve this, improve the connection of the work lead to the workpiece.

What to do if the digital display is ON but the fan is not running on my Infinium WELD STAR WS-MU4-1?
- T
  Tara TaylorAug 30, 2025
  If the digital display is on but the fan isn't running, the machine fan blades may be jammed, so unjam them. The machine fan may also not be functional, so check the fan for functionality. Finally, check the wiring and supply voltage to ensure the fan has power.

Why is the TIG electrode melting when arc is struck with my Infinium WELD STAR WS-MU4-1?
- N
  Nathaniel YoungSep 2, 2025
  If the TIG electrode melts when an arc is struck, it is possible that the TIG torch is connected to the (+) VE terminal. Connect the TIG torch to the correct terminal to resolve this.

How to fix difficult to ignite the arc on Infinium WELD STAR WS-MU4-1 Welding System?
- K
  Kelly LucasSep 5, 2025
  If it is difficult to ignite the arc, the welding voltage might be too low, or the wire feed speed may be set too high. Increase the welding voltage or reduce the wire feed speed.

Why doesn't the wire feed motor rotate when the MIG torch trigger switch is depressed on my Infinium Welding System?
- Z
  zgarciaSep 8, 2025
  If the wire feed motor does not rotate when the MIG torch trigger switch is depressed, check the wire feed speed to ensure it's not set to zero; adjust it to a non-zero setting. Also, ensure there is power supply to the wire feed motor. Finally, inspect and replace the motor PCB if faulty.
