K870 - Lincoln Electric Foot Amptrol 25ft 6-Pin Connector

Master Your TIG Welds with Smooth Control

When you are under the hood, total control over your heat input is the difference between a good weld and a perfect one. The Lincoln Electric K870 Foot Amptrol gives you that control. Designed for the professional welder who demands responsiveness, this foot pedal allows you to fine-tune your amperage on the fly. Whether you are feathering the heat for thin aluminum or punching it for maximum penetration on thick steel, the K870 responds instantly to your foot's movement. The action is smooth and predictable, eliminating the "steps" or "jumps" found in lower-quality pedals that can cause defects in your puddle.

Comfort is king during long days in the shop. That is why Lincoln includes a detachable heel rest with the K870. This simple addition provides a pivot point for your foot, significantly reducing ankle fatigue and allowing for more precise, subtle movements. The pedal sits firmly on the floor, thanks to its solid 6-pound construction and low center of gravity, so you aren't chasing it around the booth while trying to lay a bead. Plus, with a 25-foot cable, you aren't tethered tightly to your machine. You have the freedom to move around your workpiece, get into the best position, and weld without cable tension fighting against you.

This pedal connects effortlessly to your Lincoln machine via a standard 6-pin plug. It works with a huge lineup of welders, from the versatile PowerMIG 210 to the dedicated Square Wave TIG 200 and the industrial Precision TIG series. Operation is intuitive: press down to start the arc and increase heat; let up to cool the puddle and finish the weld. When you lift off completely, the pedal signals your machine to start the post-flow cycle, protecting your tungsten and keeping your weld bright and clean. Upgrade your setup with the K870 and experience the difference genuine Lincoln control makes.
