What to do if my Eastwood Welding System powers up, torch trigger is pulled, drive roller turns, gas flowing, but there is low or no weld output?
- D
  Daniel WhiteAug 5, 2025
  If your Eastwood Welding System exhibits these symptoms, several factors could be at play. First, check for low input line voltage and repair the cause. Ensure a good metal-to-metal ground connection and inspect the ground circuit for loose or open connections, repairing or replacing the ground cable if needed. Also, consider the weld surface condition; clean it thoroughly. Other potential issues include a worn contact tip (replace it), a damaged torch (replace it), a faulty control board (replace if no voltage is present), or a faulty transformer/rectifier (replace the welder if voltage is present).

Why is my Eastwood MIG175 WELDER Welding System power light on but the fan is not running?
- X
  xlopezAug 10, 2025
  Several reasons may explain why the fan isn't running on your Eastwood Welding System. It could be due to an open or loose connection in the fan circuit, which would require repair. Another possibility is a faulty fan, which would need replacement if it's a 240V AC fan. Lastly, a faulty control board could also be the cause, necessitating its replacement.

What to do if my Eastwood MIG175 WELDER has no power, even when the power switch is ON?
- D
  Daniel SimpsonAug 14, 2025
  If your Eastwood Welding System doesn't power on, start by checking the A/C voltage source at the circuit breaker or wall circuit. Inspect for loose or open connections at the power switch and repair them if necessary. If these steps don't resolve the issue, the power switch itself, the overload switch, or the control board might be faulty and require replacement.

What to do if my Eastwood MIG175 WELDER powers up, the torch trigger is pulled, the drive roller turns, but there is no gas flow and no audible click of the solenoid?
- S
  Sheila BarnesAug 19, 2025
  If there's no audible click from the solenoid and no gas flow, the issue might stem from an open or loose wiring in the gas solenoid circuit; repair any loose or open connections. Alternatively, the gas solenoid itself could be faulty and need replacement if the voltage is 240V AC. A faulty control board could also be the cause; replace it if there's no voltage.

How to troubleshoot erratic wire feed on Eastwood MIG175 WELDER?
- A
  Annette ClineAug 26, 2025
  To troubleshoot erratic wire feed on your Eastwood Welding System, start by checking if the wire feed is set too low and adjust the wire speed if needed. Inspect the gun cable for damage or bends, and straighten or replace the cable if necessary. Also, check the contact tip for blockages and clear them or replace the tip. Ensure you're using the correct inlet guide and contact tip, replacing them with the correct size if needed. Adjust the hub tension and drive roller pressure as needed, and verify you have the correct drive roller installed, replacing it if necessary.

What to do if my Eastwood MIG175 WELDER powers up, the torch trigger is pulled, the drive roller turns, but there is no gas flow even though I hear a solenoid click?
- K
  Kristi DoughertyAug 29, 2025
  If you hear the solenoid click but there's no gas flow, first check if the gas bottle is closed or empty; fill the bottle or open the valve. Also, check for any gas flow restrictions and re-attach, repair, or replace gas lines as needed.
