Feature: 1. ADJUST HEIGHT: HP105 can continuously adjust the height of the cutting torch on the uneven steel plate according to the set arc pressure value, so as to ensure that the height of the cutting torch to the steel plate remains constant 2. IMPROVE EFFICIENCY: Automatic control of cutting distance enables you to obtain smooth kerfs, reduce workpiece scrap, and improve cutting speed and efficiency 3. MOTOR CONTROL: When HP105 is working in automatic or manual state, the lift switch on the panel can be operated to control the lift of the motor 4. AUTOMATIC CONTROL: When switching to automatic mode and there is input arc voltage, the controller controls the cutting height according to the arc voltage setting value on the HP105 panel 5. WITH FITTINGS: Equipped with screws, nuts, fittings, easy for you to install, complete accessories guarantees convenient operation Specification: Item Type: Torch Height Controller Material: Aluminum alloy Dimension: Width: Approx. 225mm / 8.86in Height: Approx. 80mm / 3.15in Depth: Approx. 49mm / 1.93in Input: DC 24V±10%, 2A Lifting Motor: DC24V permanent magnet DC motor Output: DC 24V Maximum 40W Speed Control: Dual Pulse Width Modulation (PWM) with electric drive voltage feedback Arc Voltage Range: 30-250V Arc Voltage Accuracy: 1V-5V, which can be adjusted by parameters Initial Positioning: 1.

Package List: 1 x Controller5 x Screw2 x Nut6 x Accessories1 x User Manual Note: The built in isolation voltage divider of the controller defaults to input the actual arc voltage of 1:1. For some plasmas that come with a 50:1 non isolated divider, the input can be set to 50:1.1. Do not connect the actual arc voltage wire directly to the ground clip and torch cable.2. The cable from the arc voltage height controller to the motor should be shielded cable, and the shielded network should be connected to the ground of the machine.3. The plasma power supply and arc voltage height controller must be strictly grounded. Be careful to check the torch height and grounding clamp before starting the arc.4. Domestic Plasma Power Supply: Arc voltage must be taken from the high frequency arc ignition stage and before the reactor. Sampled from the position of the rectified output of the plasma.5. Any control cable and plasma torch cable should be kept as far away as possible (above 5cm) when wiring to prevent high frequency coupling into the control signal and damage to the controller and numerical control system.
