How to fix inconsistent wire feed on Thermal Arc 181i Fabricator Welding System?
To fix inconsistent wire feed on your Thermal Arc Welding System, check the following: * Replace a worn or dirty contact tip if necessary. * Replace a worn feed roll. * Reduce excessive brake tension on the wire reel hub. * Clean or replace a worn, kinked, or dirty conduit liner.
What to do if there is no gas flow in MIG mode with Thermal Arc 181i Fabricator?
If no gas flows in MIG mode on your Thermal Arc Welding System, check if: * The gas hose is damaged. If so, replace or repair it. * The gas passage contains impurities. Disconnect the gas hose from the rear of the Power Source and blow out any impurities. * The gas regulator is turned off. Turn the regulator on. * The gas cylinder is empty. Replace the gas cylinder.
Why welding arc cannot be established in MIG mode on Thermal Arc 181i Fabricator?
If your Thermal Arc Welding System's welding arc cannot be established in MIG mode, it might be due to the MIG Gun polarity lead not being connected to a welding output terminal. Connect the MIG Gun polarity lead to either the positive or negative welding output terminal as required. Another possible cause is poor or no work lead contact. Clean the work clamp area and ensure good electrical contact.
What to do if Fault Indicator is illuminated on Thermal Arc 181i Fabricator Welding System?
If the fault indicator is illuminated and the Power Source of your Thermal Arc Welding System won't commence welding, it could be because the duty cycle of the Power Source has been exceeded. Leave the Power Source switched ON and allow it to cool. Note that the fault indicator must be extinguished before you can start welding.
Why does welding wire continue to feed after releasing torch trigger on Thermal Arc 181i Fabricator Welding System?
If the welding wire continues to feed after releasing the torch trigger on your Thermal Arc Welding System, it could be because the trigger mode selection switch is in 4T latch mode. Change the trigger mode selection switch from 4T latch mode to 2T normal mode. Alternatively, the torch trigger leads might be shorted; in this case, repair or replace the torch trigger switch/lead.
What causes Thermal Arc Welding System Power Source not to feed wire in MIG mode?
If the Power Source of your Thermal Arc Welding System won't feed wire in MIG mode, it could be due to the electrode wire being stuck in the conduit liner or contact tip (burn-back jam). Check for a clogged or kinked MIG Gun conduit liner or a worn contact tip. Replace any faulty components. Another possibility is that the MIG GUN/SPOOL GUN switch is switched to SPOOL GUN. Switch the MIG GUN/SPOOL GUN switch to MIG GUN.
What to do if Thermal Arc Inverter has no weld output and no display?
If your Thermal Arc Inverter has no weld output and the front panel displays are off, several issues could be the cause. First, ensure the main power switch is set to 'ON'. If it is already on, check the line fuse and replace it if blown. Other potential causes include a faulty main power switch (replace it), a loose connection to the EMC board (tighten connections), a faulty power inverter board (replace it), a faulty control board (replace it), or a faulty display board (replace it).
Why Thermal Arc Inverter has no weld output and the display is flickering?
If your Thermal Arc Inverter shows no weld output and the front panel displays are either off or flickering, it could be due to the internal protection circuit being activated because the mains supply voltage is too high. Check that the mains supply voltage is less than 274VAC. If you're using a generator, its poor voltage regulation might be causing the issue. Connect the power source to a supply voltage less than 274VAC.
How to troubleshoot Thermal Arc Inverter with no weld output and a dark display?
If your Thermal Arc Inverter isn't welding and the display is dark, start by checking if the main power switch is turned on. If it is, the line fuse might be blown, so replace it. If that doesn't fix it, the main power switch itself could be defective, requiring replacement. Also, check for loose connections to the EMC board and tighten them. If problems persist, the power inverter board, control board, or display board might be faulty and need replacement.
Why power indicator will not illuminate on Thermal Arc Welding System?
If your Thermal Arc Welding System's power indicator won't illuminate and a welding arc cannot be established, make sure that the mains supply voltage is within 208/230VAC ±15%. The issue might be that the mains supply voltage has exceeded the voltage limits of the Power Source.
