Receptacles, Remote Controls, Switches

Control Boards, Switches, GFCI Kits, Remote Controls, Foot Pedals, & Adapters

Whether you want to upgrade your welding system or replace a worn or malfunctioning part, WeldingMart offers you a big selection of controls to help you work more efficiently and safely. In addition to welder control boards, switches and GFCI kits, we carry remote controls, foot pedals and adaptors to help you get more out of your welder. Made by trusted names such as Lincoln Electric, these products will deliver the reliable service you expect.

Our controls give you the ability to adjust the power of your welder to match the job you're working on. Remote controls like a 120V remote control switch let you amp up or down to suit the thickness of metal you're working on. They also save you the time of going back and forth between the workpiece and your welder to adjust controls. Choose from welder wireless remote controls as well as wired remotes. Foot pedals give you an effective means for getting just the right power for TIG welding.

Items like our Lincoln GFCI kit K3157-1 connect in series with the 120V receptacle on the Flextec 650 to protect you from electric shock. Each kit comes complete with a UL-listed 120V blank face ground fault circuit interrupter and full installation instructions.

If you have any questions regarding your control boards, switches and other remote control accessories, don't be afraid to give us a call or send us an email. Our highly skilled team of metal-workers are only one click away and are more than willing to steer you in the right direction. With over 50 years of industry experience, you can trust WeldingMart to get the job done right.

Frequently Asked Questions

What types of remote current controls are available for Lincoln welders, and how do I know which one works with my machine?
Lincoln offers several remote control technologies. CrossLinc® (K4345-1) communicates through the welding cable itself — no separate control cable needed — and works with CrossLinc-enabled machines like the Maverick and Frontier series. CoreLinc™ wireless (K5728-1 kit) uses radio frequency and requires a receiver (K5784-1) plugged into the machine's remote port. Wired hand-held remotes and foot pedals connect via 6-pin or 14-pin MS-type connectors depending on the machine. The Flextec® Controller (K5491-1) provides digital parameter control for Flextec-series power sources. Check your machine's spec sheet for supported remote connector type before purchasing.
What is the Flextec® Controller (K5491-1) and what machines is it for?
The Flextec® Controller (K5491-1) is a dedicated remote control interface for Lincoln's Flextec® multi-process power source series (Flextec 350X, 350XP, 350XP Construction, 335XS, and 350XP CE). It provides digital amperage/voltage parameter adjustment and process selection from a remote location, useful in structural and shipyard environments where the welder works away from the power source. It is not a universal remote — it requires the Flextec platform's specific digital communication protocol.
What is the difference between a receptacle and a remote control on an engine-driven welder?
A receptacle on an engine drive is an AC power outlet — the NEMA 5-20R (standard 120V), 6-50R (240V), or 14-50R outlets that let you run power tools, lights, and equipment from the machine's generator output. A remote control is a device that adjusts the welding output (amperage or voltage) from a distance. The Lincoln Remote Output Control (K4268-1) combines both functions: a 125 ft. cable allows current adjustment from the arc while also providing 120V receptacle outlets at the far end for auxiliary power tools at the job face.
What does the Multi-Process Switch (K3091-1) do, and when would I need one?
The Multi-Process Switch (K3091-1, also listed as Polarity/Multi-Process Switch K2642-1) allows switching between CC (constant current, for Stick/TIG) and CV (constant voltage, for MIG/Flux-Cored) output modes, and in some configurations between electrode-positive and electrode-negative polarity. This is useful on engine-driven welders that have a single output terminal pair but support multiple processes — the switch routes and configures the output to match the connected process without rewiring cables manually. Confirm the switch model is compatible with your specific engine drive before ordering.
How does a 14-pin MS-type connector differ from a Twist Mate™ connector, and why does it matter?
Twist Mate™ connectors are Lincoln-proprietary quarter-turn quick-disconnect fittings used for welding power cables — they carry high welding current. A 14-pin MS-type connector is a multi-conductor low-voltage circular mil-spec connector used for control signals between a power source and a wire feeder or control module (see K493-10, K691-10). These two connector types serve entirely different functions: Twist Mate handles power, the 14-pin MS handles communication and control signals. Never interchange them. When ordering cables or control modules, specify both the machine-side and feeder/module-side connector requirements.
