196255 - Miller 196255 Replacement Trigger Switch for M-Series and H-Series MIG Guns

Genuine Miller Replacement Trigger for M-Series Guns

Keep your welding operations running smoothly with the Miller 196255 Trigger Switch. This genuine OEM replacement part is designed specifically to restore the functionality of your Miller MIG welding guns. Over time, the mechanical trigger on a welding torch can wear out due to repetitive use, dust ingress, or accidental damage. A faulty trigger can lead to inconsistent arc starts, stuck-on gas flow, or a complete inability to weld. Rather than investing in a completely new gun assembly, this replacement switch offers a practical and economical repair solution.

The 196255 switch is the direct successor and replacement for the obsolete Miller part number 227798. It is engineered to fit perfectly inside the handle of several popular MIG gun models. Specifically, it is compatible with the Miller M-10, M-15, M-25, and M-40 series guns. These guns are commonly found on widely used power sources such as the Millermatic 140, Millermatic 140 Auto-Set, Millermatic 180, and Millermatic 180 Auto-Set. Additionally, this versatile switch fits Hobart H-10 and H-14 MIG guns, making it a valuable spare part for shops with mixed equipment.

Installation is straightforward for most users. By simply opening the clamshell handle of your MIG gun, you can access the internal wiring, disconnect the leads from the old switch, and install the new 196255 unit. The switch provides the tactile click and reliable momentary contact that professional welders expect from Miller equipment. Whether you are a hobbyist repairing a home welder or a maintenance manager keeping a fabrication line moving, using genuine Miller parts ensures that your equipment meets factory safety and performance standards.

Don't let a small component stop your production. Ensure your M-Series or H-Series gun is ready for the next job with this durable, high-quality trigger switch. It is sold individually and is an essential item to keep in your welding maintenance kit.
