640440-4 - ESAB 4-Pin Amphenol Control Plug Connector

Fix Your Control Cables with the ESAB 4-Pin Amphenol Plug

If you are dealing with a flickering remote or a TIG torch trigger that only works when you hold the cable just right, it might be time to replace the connector. The ESAB 640440-4 is the standard 4-pin Amphenol plug found on a wide range of ESAB welding machines. It is the go-to part for building custom extension cords for your foot pedal or repairing a crushed plug on your favorite hand remote. Don't let a bad connection ruin your weld or frustrate your day; swapping out a damaged plug is a quick fix that restores reliability to your rig.

This plug is built tough. We know that control cables get dragged across concrete floors, stepped on, and pulled around corners. That's why this connector features a heavy-duty outer shell and a solid locking ring. Once you screw it onto the machine, it stays put. The 4-pin layout is distinct and easy to work with. When you open it up, you'll find solder cups that are spacious enough to make soldering your wires easy, even if you don't have the steadiest hands. The strain relief on the back is designed to bite into the cable jacket, ensuring that when you pull the cord, you aren't pulling on the wires you just soldered.

Common Uses:

• Remote Controls: Perfect for repairing the cable end of your hand amperage remote or foot pedal.
• TIG Torches: Many ESAB TIG machines use this 4-pin connector for the on/off switch on the torch handle.
• Wire Feeders: Used for the control cable connection on certain voltage-sensing or remote-controlled feeder setups.

Getting your gear back in working order shouldn't be a headache. This plug gives you a factory-perfect fit for your ESAB machine. It mates smoothly with the panel receptacle, ensuring that your start signals and amperage adjustments get through every time. Keep a spare in your toolbox so a crushed plug never stops production.
