WeldKing Parts Substitution Card Pack

This pack collects the highest-value WeldKing parts-substitution cards into one fast bench set.

How to Use This Pack

• Start with the card that matches the incoming model.
• Stage the listed known-good external parts before deeper teardown.
• Move to the full guide only after the fast substitution path is exhausted.

Included Cards

Family Routing Notes

• MigSonic145: use the MigSonic145 parts card when a compact MIG clicks on and off, loses trigger after support-power trouble, or still looks like a gun, gas, or generation split. Keep stable 24 V, correct gun generation, and base-gun bare-wire feed with the tip removed ahead of any spool-gun or PCB blame.
• MigSonic252S+SS20: use the MigSonic252S+SS20 parts card when readouts freeze, gas stays open, or the feeder is blamed while the source already looks wrong. Prove the power source first with healthy readouts, jog or purge response, and idle gas behavior before feeder teardown.
• TIG200PACDC: use the TIG200PACDC parts card when DC TIG is healthy but AC is unstable, or only one pedal branch misbehaves. Keep torch, gas, remote-isolated local control, and 4K7 remote proving ahead of control-board blame.
• CoolCut40air: use the CoolCut40air parts card when the complaint depends on internal-air mode, external-air mode, or the SG55 stack fitted to the built-in-air platform.
• CUT40: use the CUT40 parts card for external-air routing, CB50 front-end, and guide-hardware complaints. Keep freehand cutting ahead of guide-hardware blame, and do not collapse it into the built-in-air CoolCut40air path.
• CUT65: use the CUT65 parts card for pressure-window, torch-head, and A81 hardware complaints on the 65 A external-air family. Keep freehand cutting ahead of stand-off or circle-kit blame.
• ThunderCut65: keep the ThunderCut65 parts card as the direct path when RV1, restrike delay, torch-head rebound, or guide carriage behavior are part of the complaint. Keep freehand cut proof ahead of any guide-hardware call.
