246376 - Miller M-100 & M-150 MIG Gun Replacement Trigger Switch

Restore Precision Control with the Miller 246376 Trigger Switch

The welding gun is the welder's primary interface with the machine, and the trigger is the critical component that initiates the entire process. When your trigger switch begins to fail, it can lead to intermittent arc starts, wire feeding issues, or complete inability to weld. The Miller 246376 Trigger Switch is the genuine OEM replacement part designed specifically to restore the functionality of your Miller M-Series MIG guns. Engineered to the exact specifications of the original equipment, this switch ensures that your welding operations remain smooth, safe, and reliable.

Designed for M-Series Compatibility

This replacement switch is built for the widely used M-100 and M-150 MIG guns. These guns are standard equipment on some of the most popular compact MIG welders in the industry, including the Millermatic 140, Millermatic 180, Millermatic 211, and the Passport Plus. It is also compatible with the M-80 MIG gun. If you are experiencing issues where the wire feeds intermittently or the gas flows but the arc doesn't strike, a worn-out trigger switch is often the culprit. Replacing it with this genuine Miller part ensures you get the correct form factor and electrical rating for your equipment.

Why Choose Genuine Miller Parts?

While generic switches might be available, only the Miller 246376 guarantees the durability and tactile response intended by the manufacturer. Welding environments are harsh; dust, metal shavings, and heat can degrade electronic components over time. This switch is constructed to withstand the repetitive cycling required during tack welding and long bead runs alike. Its blue housing is easily identifiable, and the connection points are designed for a secure fit within the gun handle, minimizing the risk of loose connections that could cause overheating or signal failure.

Easy Maintenance for Longevity

Keeping a spare trigger switch in your maintenance kit is a smart move for any professional or serious hobbyist. The installation process is straightforward, requiring only basic disassembly of the MIG gun handle to access the switch housing. By swapping out a faulty switch promptly, you prevent downtime and ensure that your Millermatic machine continues to deliver the high-quality performance Miller is known for.
