2. Overview

2.1 Technical features
SF-HC25G plasma cutting torch height controller is after many years of
practice and several generations of related products into play.
This product adopts the 32-bit arm as the core, two groups of three digital tube
display, adopts digital control mode. Do not contain linear adjustment device
internal, greatly improving the stability.
Velocity parameters can be modified, according to the lifting mechanism with
power supply and any modification.
Circuit adopts the technology of the patch. There is not internal adjustment
device, full digital control technology to ensure that the product has high
reliability.
Operation simple, two groups of digital tube display setting arc voltage and the
arc pressure respectively, concise and straightforward. Setting parameters
operating in total of three knobs.
Interface simply and control convenient, it suitable for all plasma cutting
numerical control system, can also be used alone.
It adopts the proximity switch initial alignment method.
PWM output, speed adjustable of level 255, control of motor speed precise,
several current setting, short circuit protection.
Cutting with the function of collision. When cut lips touch the steel plate, the
controller can quickly cut raise a certain distance, effective protection of
nozzle.
All input and output adopt photoelectric isolation, plasma voltage feedback
using linear photoelectric isolated, independent power supply, can very good
compatibility with the partial pressure of various brands of imported plasma
power supply.
It is integration starting arc successful judgment function, and arc successful
feedback function.

voltage. 2. Starting arc delay. 3. Locate latency. These parameters can be
directly set corresponding knob on the panel to adjust adjustment.
1. Set voltage, this can at any time by the knob to adjust the "height", on the
left side of the digital tube display voltage value set, the unit: (V), clockwise
to increase the voltage, counterclockwise to reduce voltage. Automatic
cutting according to the parameters of the controller adjust the distance
between the nozzle and the steel plate, make the arc voltage is always
closer to set the voltage. This parameter can be directly as a set of highly.
Specific set number according to the selected power supply manufacturers
provide technical parameter settings.
2. Start arc latency, punch time should be used according to the actual
perforated time settings, different thickness of steel plate and different
current when the time is also different. Clockwise to lengthen the period of
rev arc, counterclockwise to reduce arcing time.
3. Positioning delay, initial positioning time is the initial positioning, cut down
to touch with steel plate, after ascending to the time required for setting
height. The time required for different lifting mechanism to promote a
certain distance is different too. It should be set according to the actual
situation. Clockwise rotation for higher position height, counterclockwise to
reduce positioning height.
4. The speed parameters, the parameters for debugging, available to open
less than 3mm of a word or a cross screwdriver adjustment, to reduce the
clockwise and counterclockwise to increase. Adjust the parameters affect
the motor rotation speed and the response time of the whole. The knob
position as shown in figure 4-1.
5. Set position limit switch logic, S1 jumper cap inserted between 1 and 2 for
the low effective, suitable for use normally closed proximity switch. Inserted
between 2 and 3 for the high effective suitable for open still proximity switch.
The factory default for the low effective. Jumper on the panel position as
shown in figure 4-2.
6. With or without positioning function setting, S2 jumper cap inserted in
between 1 and 2 for positioning function. Inserted between 2 and 3 for no
positioning function. Jumper on the panel position as shown in figure 4-2.
