Why is the welding wire under tension on the XMT 450 CC/CV without pressing the trigger?

On this model, the welding terminals are live at all times when the 'V-SENSE' mode is selected or if the mode selector is set to 'Hot electrode'. Check the mode selector settings to ensure it matches the desired welding process.

How to resolve the issue of the welding wire being energized without pulling the trigger on the Miller XMT 450 CC/CV?

On the Miller XMT 450 CC/CV, the electrode is live by default if the mode selector is set to 'V-SENSE'. To require a trigger pull, verify the mode selector settings or adjust the configuration parameters (C1, C2, C3) to ensure the output is set for remote control instead of 'hot electrode'.

Why is the welding wire live without pressing the trigger on the Miller XMT 450 CC/CV?

This occurs if the mode selector is set to 'V-Sense Wire Feeder', which sets the output to 'Hot Electrode' by default. Verify the selector is set to the correct process for standard MIG welding if this behavior is not desired.

Why is the welding wire live without pressing the gun trigger on the XMT 450 CC/CV?

The welding wire remains live in specific modes like 'V-SENSE' (Sensitive Wire Feeder), TIG with scratch start, or Stick mode. If a trigger-controlled output is required, ensure the mode selector is set to standard MIG.

Why is the welding wire live on the Miller XMT 450 CC/CV without pressing the torch trigger?

This occurs if the machine is in 'Dévidoir Sensitif V' mode, where the output is set to 'Hot Electrode' by default. If this is not intended, check the mode selector settings (Section 5-2) or configuration functions (Section 8-5) to ensure the machine is in standard MIG mode.
