This pack collects the highest-value WeldKing model routers that turn an incoming complaint into the right document sequence.
| Model | Router | Best used for |
|---|---|---|
| CoolArc160 | workflow router | low OCV, fan slowdown, and short-run arc loss |
| CoolArc200 | workflow router | wrong 110 V or 220 V recognition, low OCV, and fan-start oddities |
| CoolTIG220 | workflow router | no TIG start, version-path faults, and remote-branch proving |
| TIG200PACDC | workflow router | DC-versus-AC TIG complaints, pedal-only faults, and gas-branch proving |
| CoolCut30 | workflow router | no-HF high-versus-low OCV splits, 24 V instability, and transfer proving |
| CoolCut40air | workflow router | internal-versus-external air proving, dual-air faults, and valve-path separation |
| CUT40 | workflow router | air-routing faults, start complaints, and guide-hardware separation |
| CUT65 | workflow router | pressure-sensitive pilot, postflow-with-no-start, and guide-hardware proving |
| ThunderCut65 | workflow router | delayed restrike, postflow-with-no-start, and RV1-sensitive pilot complaints |
| MAG211 | workflow router | chart-sensitive arc, gas-command faults, and spool-gun-only failure |
| MAG255 | workflow router | crater-fill behavior, discharge-path faults, and spool-gun-only failure |
| MultiSonic220 | workflow router | MIG-only failure, all-lights flash, and feeder run-on |
| PulseWave200 | workflow router | all-8 display, TIG no-start, and AC-versus-DC separation |
| MAG251 | workflow router | rough arc, feed-direction faults after service, and spool-gun-only failure |
| MigSonic145 | workflow router | click-cycling startup, full-speed feed, and gas-only complaints |
| MigSonic252S+SS20 | workflow router | frozen readouts, stuck-open solenoid, and source-versus-feeder separation |
MigSonic145: use the MigSonic145 router 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 router 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 router when DC TIG is healthy but AC is unstable, or only one pedal branch misbehaves. Keep simple DC TIG, remote-isolated local control, and 4K7 remote proof ahead of any broader AC-board conclusion.CoolCut40air: use the CoolCut40air router 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 router 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 router 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 router 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.CoolArc160: parts category, TIG kit 07003650, ground clamp 07000461, holder 07000460CoolArc200: parts category, TIG kit 07003750, adapter 07001825, ground clamp 07000462CoolTIG220: parts category, PRO17 torch WAT31100, FC25-HD 07002510TIG200PACDC: parts category, gas regulator branch 07000510, gas hose branch 072611120CoolCut30: parts category, electrode 07Y2517003, tip 07Y2517005, nozzle 07Y2517004CoolCut40air: parts category, electrode 07Y2517003, nozzle 07Y2517004, SG55 tip branch on the same official parts pathCUT40: parts category, guide carriage 07CV0037, extended tip 07PD0063-10CUT65: parts category, A81 torch 07001400, 2-leg stand-off 07CV0026, circle kit 07CV0052ThunderCut65: parts category, A81 ecosystem, guide carriage 07CV0051, stand-off 07CV0028MAG211: parts category, spool gun 07NS1000, U-groove drive roll 07000302MAG255: parts category, spool gun 07NS1000, U-groove drive roll 07000302MultiSonic220: parts category, aluminum kit XOM99035, spool gun 07NS1010, PRO17 torch WAT31100, pedal 07002510PulseWave200: parts category, PRO17 torch WAT31100, FC25-HD 07002510, FC25-WL 07002515MAG251: parts category, spool gun 07NS1000, drive-roll familyMigSonic145: parts category, NT-1 gun 07000422, spool gun 07NS2000, gas-side branchMigSonic252S+SS20: parts category, spool gun 07NS1000, drive roll 07NS1007
