K870-2 - Lincoln Electric K870-2 Foot Amptrol 12-Pin Remote Control

Master Your Arc with the Lincoln K870-2 TIG Foot Pedal

Achieving the perfect TIG weld requires more than just a steady hand; it demands precise control over your heat input. The Lincoln Electric K870-2 Foot Amptrol delivers exactly that, placing the power of your welding machine at your feet. Designed for professional fabricators, this remote foot control allows you to start the arc and adjust amperage on the fly, essential for managing the weld puddle when transitioning between different material thicknesses or positions.

Equipped with a 25-foot (7.6m) heavy-duty cable, the K870-2 provides the freedom to position yourself exactly where you need to be. You are no longer tethered closely to the front of your machine. This is particularly beneficial in large fabrication bays or when working on complex automotive and aerospace components. The 12-pin connector ensures a secure and reliable signal transmission to your power source, eliminating the worry of loose connections interrupting your weld.

Dynamic Amperage Control

The primary advantage of the K870-2 is its ability to provide dynamic current control.

• Start Low: Initiate the arc gently to avoid blowing through thin materials.
• Ramp Up: Press down to reach operating amperage quickly for good penetration.
• Taper Off: Slowly release the pedal to crater-fill and terminate the arc without defects.

This level of control is critical for high-quality TIG welding, reducing post-weld cleanup and ensuring structural integrity.

System Requirements

While the K870-2 fits many Lincoln Electric TIG welders with a 12-pin receptacle, specific setups may require additional components. For instance, if you are pairing this Amptrol with the Power Wave® S350, you must also install the K3001-1 Stick/TIG User Interface. This ensures the machine correctly interprets the remote signals. The pedal is built to last, featuring a robust design that resists shop debris and mechanical wear, ensuring it remains a reliable part of your welding arsenal for years to come.

Upgrade your setup with the Lincoln K870-2 and experience the difference that precise, remote amperage control can make in your daily welding operations.
