WS-180P upper board reference

This is the dedicated WS-180P upper-board page. Future real board photos, board revision notes, connector close-ups, test-point notes and practical repair evidence should be added here instead of being mixed into a broader WS board-family page.

Annotated WS-180P upper board image

This board view is for orientation before board-level checks. Use it to identify the high-frequency line socket, main transformer socket, MOSFET area, feedback controls, protection input and timing/frequency adjustment areas before measuring or replacing parts.

WS-180P upper board annotated component reference with high-frequency line socket, main transformer socket, field-effect transistor areas, indicator light, overheat protection, feedback potentiometer, fall time adjustment and pulse frequency conversion
WS-180P upper board component-orientation image. Confirm the actual board revision before using connector positions for live measurements.
Input / HF sideHigh-frequency line socket, main transformer socket and power-switching region.
Control sideIndicator light, overheat protection, feedback line potentiometer, potentiometer and function switch.
Adjustment sideFall-time adjustment and pulse-frequency conversion area used during TIG control diagnosis.

How to use this page later

When new board-layout images are available, keep them on this URL and group them by board side, connector area, control area and fault evidence.

Safety note

This page is for qualified repair technicians. TIG welding machines may contain lethal voltage and charged capacitors even after power is removed. Do not use a board image as a live-measurement map unless the exact board revision, isolation state and discharge state are confirmed.
