W7004942 - Fabricator 181i/175i 8-Pin Control Socket with Harness

Restore Your Fabricator's Versatility

If you own a Tweco or Thermal Arc Fabricator 181i or 175i, you know that its versatility is its greatest strength. Being able to switch from standard MIG to a spool gun for aluminum, or to TIG with a remote, is what makes these machines so useful. However, that versatility relies entirely on the 8-pin control socket on the front of your machine. If you have accidentally bumped your machine, tripped over a cord, or simply worn out the connector through years of heavy use, you might find that your spool gun trigger won't fire or your TIG remote is unresponsive. The W7004942 8-Pin Socket with Harness is the genuine OEM solution to get your welder back to 100% functionality.

Why Replace the Whole Harness?
Trying to repair just the socket head can be a nightmare of tiny wires and soldering in tight spaces. This replacement part comes fully assembled with the wiring harness attached. This means you don't have to worry about mixing up the pinout or creating a weak solder joint that will fail halfway through a job. The harness plugs directly into the internal circuit board of your welder, making the repair straightforward and secure. It is the exact same part that was installed in your machine at the factory, ensuring a perfect fit and reliable performance.

Symptoms of a Bad Socket
Often, a failing socket starts with intermittent issues. You might have to wiggle the spool gun plug to get it to work, or you might notice your wire speed fluctuating unexpectedly when using a remote. In severe cases, the plastic housing may be cracked, preventing the plug from locking in place. Ignoring these signs can lead to frustration and downtime. By swapping out the damaged W7004942 socket, you ensure a solid, reliable connection every time you plug in your accessories. Whether you are fabricating aluminum trailers with a spool gun or doing precision TIG work on stainless steel, a solid control connection is non-negotiable.
