    replied to Airco HF help needed please.
    The "PFC" capacitors are power factor correction capacitors that just help reduce the effective load on the power from the wall that powers the unit. Essentially, they have nothing to really do with the weld output and only affect the input current load into the machine.

  • Arc control in SMAW is a "dig" control that can add in extra amperage in low voltage conditions. This can help to keep the stick electrode from sticking to the piece you are welding on. There are some general settings to it, but it really comes down to personal preference on how high or...

It sounds like it is working right now, but it may come back. If it does, it is the PC1 control board that has the failure. This is a known issue that has...

  • The TB sees the load of the WC-24 and sees as a "I need to be ready to weld" condition and runs at the higher speed. As MMW said, you will just need ot unplug it.

  • I would check the command signal at the control board at RC6-5 in reference to RC6-4 (as shown in the attached image). If the signal makes it that far, the main board (PC1) is bad. If you don't get the 0-10 VDC at the RC6-5 connection, you need to verify that you get the 10VDC out to pins C and D...
