W7004911 - Thermal Arc Fabricator 181i Output Current Sensor

Keep Your Thermal Arc 181i Running Smoothly

Don't let a small electronic component stop your fabrication projects. The W7004911 CT Sensor, Output, 181I is the direct replacement part you need if your Thermal Arc Fabricator 181i is experiencing output sensing issues. The Fabricator 181i has long been a favorite among welders for its portability and 3-in-1 capability, but like any hardworking machine, internal sensors can wear out or fail after years of service.

This Output CT (Current Transformer) Sensor is responsible for telling your welder's computer exactly how much power is being pushed to the torch or stinger. If you have noticed that your digital amperage readout is inaccurate, or if the machine seems to lack power despite high settings, the output sensor is a common culprit. A failing sensor breaks the feedback loop, leaving your welder guessing at its own output, which results in poor weld quality, excessive spatter, or unstable arcs.
