How to fix porosity in Thermal Arc 190 Fabricator?
- T
  Tina DunlapAug 15, 2025
  To reduce porosity in your Thermal Arc Welding System, you can try the following: * Check the gas cylinder contents and flow meter. * Inspect for gas leaks between the regulator/cylinder connection and in the gas hose to the Power Source. * Ensure the hose from the solenoid valve to the MIG torch adaptor is intact and properly connected. * Shield the weld area from wind or increase the gas flow. * Minimize the distance between the MIG torch nozzle and the workpiece. * Ensure the gas holes are not blocked and gas is exiting the torch nozzle. * Prevent spatter buildup inside the MIG torch nozzle to avoid restricting gas flow. * Check the MIG gun O-rings for damage.

  If the Thermal Arc Welding System's wire feed is jerky, this may help: * Replace a worn or dirty contact tip. * Replace a worn feed roll. * Reduce brake tension on the spool hub if there's excessive back tension from the wire reel hub roll. * Clean or replace a worn, kinked, or dirty conduit liner. * Increase the Swing Arm pressure if it is low.

Why is my Thermal Arc 190 Fabricator Welding System producing a cold weld puddle?
- J
  Jennifer HardyAug 25, 2025
  A cold weld puddle in your Thermal Arc Welding System can be due to a few reasons. Check the following: * Loose welding cable connections: Ensure all connections are secure. * Low primary voltage: Contact your supply authority. * Faulty rectifier unit: Have an Accredited THERMAL ARC Service Agent test and replace the faulty component.

  If gas continues to flow after releasing the gun trigger switch on your Thermal Arc Welding System, the gas valve may have jammed open due to impurities in the gas or the gas line. Have an Accredited Thermal Arc Service Agent repair or replace the gas valve.

Why does Thermal Arc 190 Fabricator Welding System arc not have a crisp sound?
- S
  stacy95Aug 31, 2025
  If the arc from your Thermal Arc Welding System doesn't have a crisp sound, ensure the MIG torch is connected to the correct voltage polarity on the front panel. Connect the MIG torch to the positive (+) welding terminal for solid wires and gas-shielded flux-cored wires.

What to do if Thermal Arc Welding System is ON but the welding arc can not be established?
- H
  harryhallSep 7, 2025
  If the indicator light in the ON/OFF Power Switch is illuminated, but the welding arc cannot be established on your Thermal Arc Welding System, the ON/OFF Power Switch may be off. Switch the ON/OFF Power Switch on.

What to do if Thermal Arc 190 Fabricator Welding System gun trigger switch is depressed and nothing happens?
- J
  James NguyenSep 10, 2025
  If the primary input supply voltage is ON, the indicator light in the ON/OFF Power Switch is lit, but nothing happens when the gun trigger switch is depressed on your Thermal Arc Welding System: * Reconnect the gun trigger switch leads if they are disconnected. * Replace the gun trigger switch if it is defective.

What to do if Thermal Arc 190 Fabricator has inconsistent wire feed?
- C
  Cristina BurkeNov 17, 2025
  If you're experiencing inconsistent wire feed with your Thermal Arc Welding System, consider these points: * If the wire spool brake is too tight, the feed roller driven by the motor in the cabinet will slip. * If the wire spool brake is too loose, the wire spool can unwind and tangle. * Worn or incorrect feed roller size can cause issues. Use the correct ‘U’, ‘V’, or ‘knurled V’ groove drive feed roller matched to your wire type. * Misalignment of inlet/outlet guides causes the wire to rub, reducing feedability. * A liner blocked with slag can cause issues, as can excessive pressure applied to the pressure adjustment device. * Using an incorrect or worn contact tip can cause problems. Use a contact tip designed for soft electrode wires. * Poor work lead contact to the workp...
