How to fix Eastwood Welding System that will not power up?
- B
  brittneyblackAug 13, 2025
  If your Eastwood Welding System won't power up, there are several things to check: * Make sure the welder is plugged into a properly grounded, 120 Volt AC, 20 Amp power supply. * Check if the facility power source breaker has tripped and reset it if necessary. * Examine the welder breaker and reset it at the rear panel if it has tripped. * Ensure the power switch is fully in the “ON” position. * If the AMBER Overtemp Indicator is illuminated, the duty cycle may have been exceeded, causing the welder to overheat. Leave the power switch on to allow the cooling fan to run for 15 minutes until the indicator goes out, then try again.

What to do if my Eastwood Welding System will not produce an arc?
- C
  Christopher GarciaAug 17, 2025
  If your Eastwood Welding System isn't producing an arc, consider the following: * Ensure the ground cable is securely attached to the metal being welded. * Make sure the ground clamp is attached to a clean, non-rusty workpiece. Prepare the surface if needed. * Verify that the ground cable connector is fully secured to the welder terminal. * Confirm that you are using the correct welding ground clamp from the welder. * Inspect the gun contact tip for excessive wear and replace it if necessary.

Why does my Eastwood Welding System have an intermittent welding arc?
- A
  Alexis AdamsAug 20, 2025
  An intermittent welding arc on your Eastwood Welding System can be caused by: * Incorrect input voltage. Ensure you have a properly grounded, 120 Volt AC, 20 Amp power supply. * The wrong size drive roller groove. Check the drive roller size and install the correct one to match the wire size. * A poor ground. Clean the workpiece area for the ground clamp, check the condition of the ground clamp, and ensure the ground clamp attachment is tight at the welder. * Wire slipping in drive rollers. Tighten the drive roller tensioner. * An incorrect size or worn contact tip. Replace the contact tip with one of the correct size or in new condition.

How to stop wire burning back to contact tip on Eastwood Welding System?
- C
  Christopher WilsonAug 25, 2025
  To prevent wire from burning back to the contact tip on your Eastwood Welding System: * Increase the drive roller tensioner if the drive motor wire tension is insufficient, causing wire slippage. * Adjust the wire speed setting to match the welding amperage setting. Lower the welding amperage or increase the wire speed as needed. * Ensure the wire “Stickout” from the end of the contact tip is 1/4”.

What to do if shielding gas is not flowing out of Eastwood MIG Welding System gun?
- A
  Ashley ConradAug 27, 2025
  If shielding gas isn't flowing from your Eastwood MIG Welding System gun: * Open the gas flow knob on the regulator further to increase gas flow. * Check if the gas cylinder is empty and refill it if necessary. * Ensure the MIG gun connector is fully inserted into the socket of the welder, tightening the hold-down wing nut. * Inspect the O-rings on the MIG gun for damage or if they are missing, and replace them. * Check for gas leaks from the hose or fittings; tighten fittings or replace damaged parts. * Replace the gas diffuser if it's plugged with spatter.

Why won't the wire feed on my Eastwood Welding System?
- D
  Dale RobinsonAug 31, 2025
  If the wire won't feed on your Eastwood Welding System: * Tighten the drive roller tensioner if it's not adjusted properly, causing slippage. * If the AMBER Overtemp Indicator is illuminated, the duty cycle may have been exceeded, causing the welder to overheat. Leave the power switch on to allow the cooling fan to run for 15 minutes to cool the welder, then try again.

What causes Eastwood Welding System to overload and illuminate the AMBER Over-temp Indicator?
- F
  Frank StewartSep 4, 2025
  If your Eastwood Welding System overloads and the AMBER Over-temp Indicator illuminates, it is because the duty cycle has been exceeded and the welder has overheated from excessive usage. Leave the power switch on, allowing the cooling fan to run for 15 minutes to cool the welder, then try again.

Why is the wire binding up ahead of the drive feed rolls on my Eastwood Welding System?
- R
  Robert AlvarezSep 8, 2025
  If the wire is binding up ahead of the drive feed rolls on your Eastwood Welding System, it's likely because the wire tension is set too high. Loosen the drive roller tension.
