Why does my Forney Welding System wire push the gun back from the workpiece?
If the wire pushes the gun back from the workpiece, it means that the gun is held too far from the workpiece. Hold the gun at the right distance.
What to do if my Forney Welding System has low output or non-penetrating weld?
If you're experiencing low output or non-penetrating welds, first adjust the welding parameters. Then, verify you are not using too long or improper extension cord. A proper extension cord should be #12 AWG wire or heavier, and no longer than 25 ft. Also, make sure you are using the correct type and size wire, which is 0.030” (0.8mm) E71T-GS self-shielding flux-core wire. Check for poor ground or gun connections. Ensure that you are using the correct size and that the contact tip isn't worn, use a 0.030-inch (0.8mm) contact tip with the 0.030-inch (0.8mm) wire and replace it if worn. Have a qualified electrician verify the voltage at your outlet and the circuit wiring is sufficient for 20A if the voltage is appropriate. Finally, decrease stick-out (the amount the wire extends past the cont...
What to do if both INDICATOR LEDS are illuminated and there is no output power from the Forney welder?
Allow welder to cool at least 10 minutes with machine ON (observe and maintain proper duty cycle). FAULT/THERMAL OVERLOAD INDICATOR LED (3) should turn off after the machine has cooled. Check for obstructions blocking air flow and ensure that there are 12 inches of clearance between any obstacles and the vents on all sides of the machine. Check the voltage of your outlet. If it is 10% more or less than 120V, call a qualified electrician.
What to do if neither INDICATOR LED is illuminated and nothing works on the Forney welder?
Turn machine ON with ON/OFF SWITCH. Make sure machine is plugged in. Verify that circuit breaker has not been tripped. Reset if needed. Verify output power from the outlet.
What to do if feed motor operates but wire will not feed on my Forney Easy Weld 140FC-i?
Replace wire feeding motor. Also, re-cut wire so it is square with no burr. Clear with compressed air or replace liner if liner blocked or damaged.
What causes the weld deposit to be too thick on my Forney Easy Weld 140FC-i?
A weld deposit that is too thick can be caused by moving the gun over the workpiece too slowly, so move the gun faster. It can also be caused by welding voltage/amperage that is too low, so increase the welding voltage/amperage.
What causes the weld deposit to be 'stringy' and incomplete on my Forney Easy Weld 140FC-i Welding System?
A 'stringy' and incomplete weld deposit is caused by moving the gun over the workpiece too quickly. Move the gun slower.
What causes my Forney Easy Weld 140FC-i gun nozzle to arc to the work surface?
The gun nozzle arcing to the work surface is caused by slag build-up inside the nozzle or the nozzle being clogged. Clean or replace the nozzle as needed.
Why does my Forney Easy Weld 140FC-i produce poor quality welds?
Poor quality welds can result from a rusty, painted, oily, or greasy workpiece, so ensure the workpiece is clean and dry. Also, rusty or dirty wire can cause this issue, so ensure the wire is clean and dry. Finally, check the ground clamp/workpiece connection and all connections to the machine, as poor ground or gun contact can lead to poor weld quality.
Why is my Forney Easy Weld 140FC-i ground clamp, ground cable, and/or welding cable getting hot?
The ground clamp, ground cable, and/or welding cable may get hot due to a bad or loose ground connection. Check the connection of the ground clamp and gun to the machine. Also, check the connection of the ground cable to the ground clamp, tightening the cable connection if needed. Make sure the connection between the ground clamp and workpiece is good and on clean, bare metal (not painted or rusted).
