- Trigger switch failure repair: Replace a failed micro-switch inside the trigger assembly without purchasing a new gun body or complete gun assembly.
- Preventive maintenance: Keep a trigger kit on hand for high-production MIG welding operations where gun downtime is costly.
- Rental fleet and school shop maintenance: Economical way to maintain MK Products Prince guns in training facilities or equipment rental fleets with heavy use cycles.
The 005-0550 Trigger Kit is an OEM MK Products part engineered specifically for the Prince MIG gun handle. It is not a universal trigger kit and is not cross-compatible with other MK Products gun models (such as the Cobra or Python) unless explicitly stated in MK's parts cross-reference.
Before ordering, confirm your gun model is the Prince series. The handle designation and part number are typically printed on a label on the gun body or documented in the gun's original spec sheet.
