KickingHorse Fault-Branch Matrix

This matrix groups recurring KickingHorse failures by subsystem so technicians can jump straight to the right branch before they over-diagnose a small machine as a full power-source failure.

How to Use This Matrix

Branch Matrix

Subsystem branch Recurring symptoms Strongest models to open first Best local references Prove before escalation
Utility path, branch quality, and current return weak arc, bad arc blow, hard start with normal OCV, machine acts better on another outlet, plug or clamp heating A100, A220, MA200TS workbook sheets A100, A220, and MA200TS, plus owner manuals for fitted input expectations for A100, prove real 120 V / 20 A or a healthy 3 kW generator path first; for A220, prove real 208/230 V and ideally 50 A or a healthy 5 kW generator path first; then prove clamp bite, hot current-path hardware, and correct DCEN / DCEP before internal repair; then move into the A100 router or A220 router
Support power, startup collapse, and fan-related branch one-second power-up then shutdown, blinking power light, fan oddities, machine wakes and collapses A100, MA200TS, P40 MA200TS_Service_manual.pdf, B.067RM.419-C_main.pdf, workbook sheets A100, MA200TS, and P40 wall outlet quality, switch path, fan branch, and support supply before condemning the main inverter; then move into the A100 board opening map when the complaint stays internal
Display, control, and feedback branch display pegged at max, wrong A or V reading, strange panel behavior, feed and display faults together, process button trouble M185, MA200TS MA200TS_Service_manual.pdf, local MA200TS panel photos, workbook sheets M185 and MA200TS whether welding still works with bad display, whether preset-versus-actual display behavior is wrong, and whether the fault follows the display or feedback branch rather than the power stage
Wire-feed, trigger, and torch-front-end branch no wire feed, wire feeds at power-up, poor arc at higher wire-speed settings, breaker trip, front-end misassembly, birdnest F130, M185, MA200TS B.067RM.600-C.pdf, B.067RM.601-D.pdf, local MIG workbook sheets, and multiprocess service notes bare-wire feed with tip removed, trigger path, drive pressure, correct torch-front-end assembly, and for F130 the correct 0.035 in baseline or proper 0.030 in conversion
MIG-only versus shared power-source branch stick works but MIG does not, one process healthy while another is dead, shared machine blamed too early MA200TS, M185, F130 workbook sheets MA200TS, M185, and F130 one healthy baseline process first, then retest the failing branch; for M185 prove real 208/230 V source and sane inductance first, and for F130 prove real 120 V / 20 A or 3 kW source first
Plasma HF, control, and torch-stack branch no HF, HF but no OCV, air but no cut, pilot without transfer, fan-voltage drift, blocked orifice P40 B.067RM.418-C_HF.pdf, B.067RM.410-C_control.pdf, B.067RM.419-C_main.pdf, P40_parts_breakdown.pdf, and local P40 reference images 1.5 mm HF gap, 24 V support to HF board, fresh SG55 stack, clean clamp, and dry air under flow
Package, accessory, and kit branch aluminum complaints on multiprocess unit, TIG branch weirdness, wrong package installed, post-service fitment problems MA200TS, P40, A220 P40_parts_breakdown.pdf, local multiprocess workbook sheets, and the A220 workbook sheet exact fitted kit, torch, clamp, lead, and regulator package before electronics diagnosis; for A100 and A220, stop if the complaint is really improvised TIG use because that is not a supported process path

Fast Starting Points

If the complaint sounds like... Start here
A100 weak arc or collapse that changes with outlet, clamp, or polarity utility path, branch quality, and current return
A220 top-end weakness or bad arc blow that changes with source, clamp, or polarity utility path, branch quality, and current return
unstable stick output that changes with outlet or clamp quality utility path, branch quality, and current return
powers up for a second then dies, or blinks strangely support power, startup collapse, and fan-related branch
wire feed and display are both wrong display, control, and feedback branch
feed problem with odd torch or front-end behavior wire-feed, trigger, and torch-front-end branch
compact MIG only works on one outlet or after changing wire size MIG-only versus shared power-source branch
one process works and another does not MIG-only versus shared power-source branch
plasma has air or HF but still will not cut plasma HF, control, and torch-stack branch
