Why is there no weld or control power in my ESAB Welding System?
The possible causes for no weld or control power are: * Primary input power might not be available. Check for voltage at the primary input. * There might be a faulty connection, primary input cable, or power switch (S3). Repair or replace the cable or switch (TGS1) as necessary. * A line fuse might be blown. Replace the fuse. If it blows again, contact an ESAB representative.
Why is the welding current erratic on my ESAB Welding System?
Erratic welding current in your ESAB Welding System can be caused by: * A poor workpiece connection. Check the workpiece grounding connection. * Loose welding connections. Check all connections. * Wrong polarity. Check for correct polarity.
What to do if there is no welding power in my ESAB Welding System?
If you have no welding power, it could be due to: * The thermostat has opened. Wait 15 minutes with the fan running. If there is still no power, contact an ESAB representative. * A shorted diode in the main rectifier. Check the diodes and replace if required. * An open in the wiring. Check all wiring.
How to troubleshoot low or stopped shield gas flow in ESAB Welding System?
If the shield gas flow is low or stopped, consider the following troubleshooting steps: * Check the flow at the outlet and replace any faulty items. * Ensure the torch nozzle is not too far from the work. Maintain a 1/4" (.6 mm) wire protrusion and hold closer to the work. * Inspect the regulator or adapter for faults. Check the flow at the outlet and replace any faulty items. * If the gas solenoid valve (SOL) is faulty, replace it.
How to fix an ESAB Welding System when the motor does not run?
If the motor does not run, you can try the following: * Check for a blown fuse. If blown, check that the motor is not binding before replacing the fuse. * Check for continuity across the speed potentiometer (POT) and wiper contact. The voltage from the center tap to the MIN end should vary from 0 to 5.4 VDC as the potentiometer is rotated clockwise. * Check the wiring for continuity. Then turn the power ON and check the feeder printed circuit board connector (PL1). * Press the torch trigger and check for voltage across the motor (Pins 4 to 7) of the speed control board; it should vary from 1 to 24 VDC as the speed control potentiometer is rotated clockwise.
What to do if the fan does not run on my ESAB Welding System?
If the fan does not run, replace the fan motor (M1).
