10-5518 - Thermal Arc Pro-Wave 300GTSW Replacement Main PCB Control Board

Get Your Pro-Wave 300GTSW Back to Work

When your trusted Thermal Arc Pro-Wave 300GTSW goes down, it stops production and costs you money. The 10-5518 Replacement PCB is the solution to get your high-performance TIG welder running like new again. Electronic components can fail over time due to heat, age, or power surges, leaving you with a machine that won't weld or won't hold settings. Instead of scrapping a valuable industrial welder, replacing the main control board is a cost-effective repair that brings your equipment back to factory specifications.

This genuine replacement part is designed specifically for the Pro-Wave 300G and 300GTSW models. It handles all the "thinking" for your welder—controlling the arc stability, the pulse settings, and the AC wave balance that makes these machines so good for aluminum and precision fabrication. Because it is an exact fit replacement, you don't have to worry about compatibility issues or "retrofitting" a universal part. It plugs directly into your machine's existing harness system.

Investing in the 10-5518 PCB protects your original investment in Thermal Arc technology. Whether you are a professional repair technician or a shop owner managing your own equipment maintenance, this board provides the reliability you expect. Don't let a fried circuit board force you to buy a brand new machine. Swap out the damaged board with the 10-5518, verify your connections, and get back to laying down perfect beads on stainless and aluminum.
