About this item

SF-HC25G Torch Height Controller SF-HC25K Plasma THC with Encoder Knobs for CNC Plasma Cutting Machine


-The SF-HC25G/SF-HC25K Plasma Torch Height Controller is a torch height automatic control module specifically designed for portable plasma cutting machines.

-The SF-HC25G/SF-HC25K plasma torch height controller is easy to operate, easy to debug, affordable, and fully digitally controlled for reliable performance. It is an ideal accessory product for welding and cutting equipment manufacturers. The main unit and panel split structure make it ideal for portable cutting machines.


-The plasma torch height controller is based on years of practice and several generations of related products.

-This product uses 32-bit arm as the core, two sets of 3-digit digital tube display, digital control. The linear adjustment device is not included inside, which greatly improves the stability.

-The speed parameters can be modified and can be modified arbitrarily according to the power supply and lifting mechanism.

-The circuit adopts the chip technology, there is no adjustable device inside, and the full digital control technology ensures the high reliability of the product.

-Simple operation, two sets of digital tubes display the set arc pressure and the actual arc voltage respectively, which is simple and intuitive. There are 3 knobs for setting parameter operations.

-Easy to control interface, suitable for all plasma cutting CNC systems, can also be used alone.

-Adopt the proximity positioning mode of the proximity switch.

-Pwm output, 255 speed adjustable, precise control of motor speed, multi-speed current setting, short circuit protection.

-The anti-collision function of the cutting tool. When the cutting nozzle touches the steel plate, the controller will quickly lift the cutting tool a certain distance to effectively protect the cutting nozzle.

-All input and output are opto-isolated. Plasma voltage feedback adopts linear opto-isolation and independent isolated power supply. It is very compatible with imported plasma power supplies of various brands with its own voltage divider.

-Integrated arc start success judgment function, arc start success feedback function.
