NY-D02 Double Pulse Encoder Time Current Spot Welding Controller Control Board with Adjustable Digital Display 100A/40A Optional

Features:
Welding pulse for a single and double pulse can be switched to use, anyone welding time is set to 0, can become a single pulse welding.
With network voltage compensation, according to the changes in electricity, automatically adjust the output to ensure that the same parameters in the welding with the same heat to maintain the same, the solder joint.
Parameter adjustment for the encoder input mode, more accurate and convenient.
With the welding count function, 0-999 counting ranges, and can be saved.
Time input 0-100 cycles, unit cycle (1 cycle is 20ms) current input (300-999).
The current adjustment step is 0.1% and the regulation is more subdivided, you can customize it if there are other ranges required.
3 blue 0.56 inch digital tube, the size of the browser than the knob control version of the large, our knob digital tube is 0.36 inches.
Onboard power, pedal, trigger, run, time, current, interval, time, current indicator, so that each state has a clear indication.
The whole board using STM8 industrial microcontroller to do the main control core.
Strong and weak through the optocoupler isolation, operation more safety.
Power cord and foot switch line with screw-free terminal, more convenient and reliable.
Design a reliable zero-crossing detection circuit to ensure that the SCR phase shift accurate.
The controller is compatible with 100A-40A thyristor.
Comes with a 9V 2W power transformer, copper coil, with stable working voltage and high working frequency.
Wiring instructions:
3.1. Operation Indicator Description
3.2. Display status description:
The controller has three kinds of operating status, welding preparation, parameter query, parameter change.
Welding preparation: running light is stay bright, time, current, interval, time, current indicator off.
Parameter query: running indicator light off, time, current, interval, time, current corresponding to the amount of light, the digital tube is stay bright, the value of the display for the corresponding parameter values.
Parameter change: Run indicator light off, time, current, interval, time, current corresponding to the amount of light, digital tube flashing, the value displayed for the corresponding parameter value change value.
3.3. Welding preparation:
Through the (Select / adjust) encoder counterclockwise rotation, so that the running light is stay on, time, current, interval, time, current indicator light off, this time can be welded, digital tube display value for the current welding count
3.4. Voltage calibration:
Because the controller with a network pressure compensation function, so when the first installation, to carry out voltage calibration, just one can be calibrated. (As long as you do not replace the power transformer, you do not need to re-calibration)
Calibration operation:
In the running state, long-press the micro-open until the time, current, interval lights all light, then use a multimeter to measure the mains voltage, such as the measured voltage of 225V, then, rotary encoder, the digital tube Display the value of 225 can be, and then double-click the microswitch, exit the calibration.
3.5. Count is cleared:
The controller with a welding count function, in the operation of welding, each welding, welding count automatically increased by 1. Count ranges 0-999.
If you want to clear, in the running state, double-click the [enter / save] button, the count is automatically cleared.
