Why is my weld bead too small with my Thermal Arc Inverter?
If the weld bead is too small, penetration is insufficient, or ripples in the bead are widely spaced apart when using your Thermal Arc Inverter, the travel speed is likely too fast. Reduce the travel speed.
Why does the electrode melt when I strike an arc with my Thermal Arc Inverter?
If the electrode of your Thermal Arc Inverter melts or oxidizes when striking an arc, several factors could be responsible. Ensure gas is flowing to the welding region and check the gas lines for kinks or breaks, as well as the gas cylinder contents. Clean the torch if it's clogged with dust and replace the gas hose if it's cut. Clear any impurities from the gas passage by disconnecting the gas hose from the torch, raising the gas pressure, and blowing them out. Make sure the gas regulator and torch valve are turned on. If the electrode is too small for the welding current, increase its diameter or reduce the current. Finally, ensure the Wave Balance is set below 50%; if it's higher, reduce it or increase the electrode size.
Why does the welding current reduce when welding with my Thermal Arc Inverter?
If the welding current reduces while welding with your Thermal Arc Inverter, it may be due to a poor work lead connection to the work piece. Ensure that the work lead has a positive electrical connection to the work piece.
What to do if the arc can not be established on Thermal Arc Inverter?
If the arc can not be established on your Thermal Arc Inverter, verify that the primary supply voltage is switched ON and the Welding Power Source switch is also ON. If these are correct, an Accredited Thermal Arc Service Agent should inspect and repair the welder, as there may be loose connections internally.
What causes excessive penetration in butt joint with Thermal Arc Inverter?
If the weld bead is too wide, there's excessive bead build-up, or excessive penetration in a butt joint when using your Thermal Arc Inverter, the travel speed is likely too slow. Increase the travel speed.
What does E93 error code mean on Thermal Arc Inverter?
The E93 error code on your Thermal Arc Inverter indicates that the memory chip (EEPROM) on the control PCB cannot read/write weld parameters. This may be due to a memory chip (EEPROM) error on PCB5 (WK- 4919). Replace PCB5 (WK-4919). Accumulation of dust.
Why is the TIG electrode contaminated on my Thermal Arc Inverter?
If the TIG electrode of your Thermal Arc Inverter has been contaminated because the gas flow shut off before the programmed POST-FLOW Time elapsed, it's because the Weld Process Mode (STICK, HF TIG, LIFT TIG ) was changed before POST- FLOW gas time had finished. To prevent this, do not change the Weld Process Mode before the POST-FLOW gas time has finished.
What does E82 error code mean on a Thermal Arc Inverter?
The E82 error code on your Thermal Arc Inverter indicates that the link switch plug is not connected. Check the link switch plug connection at connector CN4 on PCB3 (WK-4819). Refer to visual inspection section. If the error code E82 still appears after checking the above, then replace PCB3 (WK-4819).
What does E83 error code mean on Thermal Arc Inverter?
The E83 error code on your Thermal Arc Inverter indicates that the CPU is checking the mains supply (input) voltage when the on/off switch on the rear panel of the machine is turned ON. This can be caused by several issues. Check the input power supply cable electrical connections to ensure they are secure. Verify that the wiring and connections at connector CN1 on PCB9 (WK-4917) and connector CN1 on PCB2 (WK-4983) are connected firmly. Check the connections from PCB2 (WK-4983) to PCB3 (WK-4819) are connected firmly. If the error code E83 still appears after checking the above, then replace PCB3 (WK-4819).
