To Next PageTo Next PageWhy is my Thermal Arc Inverter weld bead too wide or excessive bead build up or excessive penetration in butt joint?
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 to resolve this.
What to do if my Thermal Arc Inverter welding current reduces when welding?
If the welding current reduces during welding, first, check and tighten all welding cable connections. Ensure you are using the proper size and type of cable. Also, replace the electrode if it is in poor condition and verify the output torch connections to confirm correct welding polarity.
Why does my Thermal Arc Inverter have gas pockets or voids in weld metal (Porosity)?
Porosity, or gas pockets in the weld metal, can occur for a few reasons. The electrodes might be damp; dry them before use. The welding current could be too high; reduce it. Also, surface impurities like oil, grease, or paint can cause this; clean the joint before welding.
What to do if my Thermal Arc Inverter electrode melts when arc is struck?
If the electrode melts when the arc is struck, it could be due to two main reasons. First, check if the electrode is connected to the '+' terminal and connect it to the '–' terminal instead. Second, if the WAVE BALANCE is greater than 50%, reduce it to below 50% or increase the electrode size.
What to do if my Thermal Arc Inverter welding arc can not be established?
If a welding arc cannot be established, first ensure that the work clamp is properly connected to the workpiece, or that the work/torch leads are connected to the correct welding terminals. If using a torch lead, connect it to the '–' terminal. Finally, check the gas flow rate, ensure the cylinder isn't empty, and verify that the torch valve is on. Select the right flow rate, change cylinders or turn torch valve on.
Why is there no gas flow when the torch trigger switch is depressed on my Thermal Arc Inverter?
If there's no gas flow when the torch trigger is depressed, several issues could be the cause. Check if the gas hose is cut and replace it if necessary. Impurities in the gas passage can also be a problem; disconnect the gas hose from the rear of the Power Source, then raise the gas pressure and blow out any impurities. Ensure the gas regulator is turned on. Finally, the torch trigger switch lead might be disconnected, or the switch/cable could be faulty; reconnect the lead or repair the faulty switch/cable.
What causes crack occurring in weld metal soon after solidification commences with my Thermal Arc Inverter?
If cracks occur in the weld metal soon after solidification, it could be due to a few reasons. The rigidity of the joint might be a factor; redesign the joint to relieve severe stresses or use crack-resistant electrodes. Insufficient throat thickness can also contribute; travel slightly slower to allow greater build-up in the throat. Finally, a cooling rate that is too high can cause cracking; preheat the plate and allow it to cool slowly.
Why the welding arc cannot be established with my Thermal Arc Inverter?
If the welding arc cannot be established, first ensure that the primary supply voltage is switched ON. Next, check that the Welding Power Source switch is also switched ON.
Why is my Thermal Arc Inverter weld bead too small or insufficient penetration or ripples in bead are widely spaced apart?
If the weld bead is too small, penetration is insufficient, or ripples in the bead are widely spaced when using your Thermal Arc Inverter, the travel speed is likely too fast. Reduce the travel speed to correct this.
What causes a dirty weld pool in my Thermal Arc Inverter?
A dirty weld pool can result from a couple of issues. The electrode might be contaminated through contact with the workpiece or filler rod material; clean the electrode by grinding off the contaminants. Alternatively, the gas could be contaminated with air; check the gas lines for cuts and loose fittings or change the gas cylinder.
