Measurement index
Welder Connector and Measurement Point Index
A connector and voltage evidence index for LGK60L, LGK100L and MIG200DL service workflows.
Quick Answer
This index collects connector and voltage evidence created from the LGK60L, LGK100L and MIG200DL materials so users can find measurement points directly.
- Use this page when the symptom route says to check a named connector such as X13, X14, X16, P12, P14 or P17.
- It is not a replacement for the full fault route; it is a measurement-point navigation page.
- Always discharge capacitors and follow qualified high-voltage safety procedures before measurement.
Measurement-point index
| Connector / evidence | Machine family | Where it is used |
|---|---|---|
| X16 DC24V | LGK60L | Fan-not-running route; board-side fan/DC24V output evidence. |
| X17 AC15V-0V-15V | LGK60L | Fan/control abnormal route; control transformer secondary evidence. |
| X13 DC5V | LGK100L | Fan runs but display off; digital meter supply evidence. |
| X7 0-27V-36V / 15V-0-15V | LGK100L | Protection light and no-output rail evidence. |
| X14 DC15V / -DC15V / signal | LGK100L | Hall sensor feedback, protection and weak-current diagnosis. |
| P12 DC540V | MIG200DL | Power-board DC bus evidence for display/trigger/output routes. |
| P6 DC5V | MIG200DL | Digital meter supply evidence. |
| P13 | MIG200DL | Torch switch and jog signal path. |
| P14 DC2-22V | MIG200DL | Wire-feed motor output path. |
| P17 DC24V | MIG200DL | Gas-valve supply path. |
| CON5 AC220V | MIG200DL | Cooling fan output path. |
| CON6 AC380V | MIG200DL | Control-transformer supply branch. |
