7. Troubleshooting

This section addresses common issues you might encounter during operation.

• No Power: Check the power cord connection, circuit breaker, and ensure the power switch on the machine is in the 'ON' position.
• No Arc (MMA/TIG):
  • Ensure the ground clamp is securely attached to a clean section of the workpiece.
  • Check that the electrode/tungsten is properly installed and not worn out.
  • Verify the current setting is appropriate for the material and electrode size.
• Poor Cut Quality (CUT):
  • Check air pressure and flow rate.
  • Inspect plasma torch consumables (tip, electrode, shield cup) for wear and replace if necessary.
  • Ensure proper cutting speed and standoff distance.
• Unstable Arc (TIG/MMA):
  • Check for loose connections.
  • Ensure the workpiece is clean and free of rust or paint.
  • For TIG, ensure the tungsten electrode is correctly ground and free from contamination.
