Lincoln Electric Voltage Selector Switch S25351-17

Restore Your Welder's Performance

Is your Lincoln MIG welder stuck on one heat setting? Does the voltage knob feel loose, or does the machine fail to arc when you select certain power levels? You may be dealing with a faulty Heat Range Switch. The Lincoln Electric S25351-17 is the genuine replacement part you need to get your machine back up and running like new. This switch is the control knob behind your voltage settings, allowing you to dial in the perfect heat for thin sheet metal or thicker steel.

Over years of use, the internal contacts of your selector switch can wear out from the electrical current or mechanical fatigue. When this happens, you lose the versatility that makes your welder useful. Instead of struggling with a machine that runs too hot or too cold, simply swap out the defective switch. This is an authentic Lincoln Electric part, meaning it isn't a cheap knock-off that requires modification to fit. It drops right into the existing mounting location and connects to your machine's wiring harness exactly as the original did.

Don't let a small broken part keep your welder gathering dust. Whether you are running an SP-series machine or a Weld-Pak, this switch is often the key to solving output issues. Ensure your welds are strong and your machine is reliable by installing the correct OEM replacement switch.
