What to do if there is no weld output and wire feed, but the fan runs on my Hobart Welding System?

If your Hobart Welding System isn't providing weld output, and the wire isn't feeding but the fan is running, here are some things to check: * Ensure the Voltage switch S2 is correctly positioned. Rotate the knob until it clicks into place at the desired range setting. * Make sure the gun trigger leads are securely connected to receptacle RC3. * Check the continuity of the gun trigger leads, and repair or replace the gun if needed. * Inspect the Voltage switch S2 for continuity, and replace it if necessary. * Examine the diodes in the main rectifier SR1, and replace them if necessary. * Look for signs of winding failure in the main transformer T1. Check the continuity across windings, ensure proper connections, and check secondary voltages. Replace T1 if necessary. * Check t...
