Restore Your Welder's Connection with ESAB OKC 25

Is your welding lead feeling loose at the machine connection? Or perhaps you've noticed the plug getting uncomfortably hot during use? These are classic signs of a worn-out machine socket. The ESAB Machine Contact OKC 25 is the direct replacement part you need to fix these issues and get back to welding with confidence. This is the "female" socket that mounts directly onto the front panel of your welder, designed to accept the smaller "Dinse" style twist-lock cable connectors (size 10-25).

A solid connection is the foundation of a good weld. If your machine contact is worn, electricity struggles to jump the gap, creating resistance. This resistance creates heat—enough to melt insulation or damage your machine's internal wiring—and causes voltage drops that make your arc sputter and act unpredictably. By swapping out your old, pitted socket for a fresh ESAB OKC 25 contact, you ensure that 100% of your machine's power reaches the puddle. The brass construction is heavy-duty and designed to handle the amperage without overheating, provided the connection is kept clean and tight.

The "OKC 25" designation means this plug is the smaller of the two common industry sizes (the larger being OKC 50 or 95). It is typically found on TIG inverters, smaller MIG machines, and portable stick welders. The twist-lock bayonet style is a favorite among welders because it is quick to connect and disconnect but won't pull out if you tug on the cable. Installation is generally simple, requiring access to the back of the front panel to secure the nut and connect the internal power strap.

Don't let a cheap or worn-out connector ruin your welds or your machine. Using genuine ESAB parts guarantees the fit and finish matches your equipment. Whether you are building a new lead extension or repairing a trusty shop welder, this panel socket provides the secure, snap-tight feel of a brand-new machine. Keep your arc smooth and your connections cool with this essential repair part.
