What to do if the electrode melts or oxidizes when an arc is struck on my Thermal Arc Welding System?

If the electrode melts or oxidizes when an arc is struck while using your Thermal Arc Welding System, it could be due to several reasons. It might be because there's no gas flowing to the welding region, the torch is clogged, the gas hose is cut, the gas passage contains impurities, the gas regulator or torch valve is off, the electrode is too small, or the WAVE BALANCE is set too high. To address this, check the gas lines and cylinder, clean the torch, replace the gas hose if needed, blow out impurities from the gas passage, turn on the gas regulator and torch valve, increase the electrode diameter or reduce the welding current, and reduce the WAVE BALANCE to below 50% or increase the electrode size.
