951016 - ESAB 10-Pin Combicon Connector Plug

Fix Your Welder with the ESAB 951016 10-Pin Plug

If you are troubleshooting an ESAB welder and have traced the problem down to a loose, burnt, or cracked connector on the control board, the ESAB 951016 10-Position Combicon Connector is likely the part you need. Welding machines vibrate, get dragged around, and operate in dirty environments; over time, the plastic connectors that plug into the circuit boards can become brittle or the screw terminals can strip out. A bad connection here can mean your wire feeder stops feeding, your voltage fluctuates, or the machine simply won't trigger. Don't try to jam wires directly into the board or use a generic plug that doesn't lock in tight—use the genuine replacement.

This is a 10-pin (or 10-position) connector block, often referred to as a Combicon style plug. It is designed to plug directly into the matching header on your machine's PCB. It features ten individual wire ports, usually secured with small screws. This makes it very easy to replace in the field. You simply strip your control wires, insert them into the correct numbered ports on this new connector, tighten the screws, and plug it back into the board. No soldering is required for the plug side, making this a quick fix that can be done right on the shop floor.

Using the correct ESAB part is crucial because the pin spacing (pitch) and the keying of the plastic housing must match the board exactly. A forced fit with a generic part can damage the expensive circuit board pins. This 951016 connector is built to handle the low-voltage control signals reliably. It provides a snug friction fit that resists vibrating loose during welding operations.

Whether you are rebuilding an older wire feeder or repairing a damaged cable harness interface, this plug restores the reliability of your machine's controls. Keep your arc stable and your settings accurate by ensuring every electrical connection in your power source is solid. This simple plastic and metal part is often the difference between a machine that acts up constantly and one that runs smooth all day.
