THC3T-02 is a compact torch height controller for CNC plasma cutting, with a built-in 1:50 voltage divider so it works with plasma cutters that have no divided arc voltage output. It reads the arc voltage while the torch is cutting and automatically raises or lowers the torch to keep a constant distance to the plate, so cut quality stays consistent even when the sheet is warped or the cutting bed is not perfectly flat. Signal-processing algorithms stabilize the voltage reading, and a smooth-motion algorithm prevents jerky Z movement. Unlike controllers that only send up\/down signals to the CNC, THC3T-02 drives the Z-axis motor driver directly with Step\/Dir signals for faster response and higher accuracy. It detects ARC OK automatically, self-calibrates to the arc voltage of your plasma cutter, and integrates with Mach3 software. Designed and built by Robot3T in Vietnam.<\/p>\n\n\t\tRequest a quote<\/span>\n\t<\/a>\n \n\t\tWhatsApp +84 974 908 615<\/span>\n\t<\/a>\n\n
