Key Technical Benefits

The circuit card assembly is responsible for the precise timing and control logic required for clean, consistent plasma cuts. A failing board can result in erratic arcs, inability to pilot, or intermittent shutdowns. Installing a fresh, factory-calibrated board eliminates these variables, returning the machine to its factory-default reliability.
