We have the AC 9V in my store :AC 220V to AC 9V Power Supply transformer For Spot Welding Controller
We have the spot welding pen in my store :handheld 18650 battery spot welding pen copper DIY for Spot Welders
The control panel of the spot welding machine is a controller which is independently developed for the DIY or the simple resistance welding. The principle of silicon controlled phase shifting triggering is adopted to adjust the time and the current to achieve the purpose of welding.
The main features of this controller:
1: the use of STM8 industrial microcontroller control center.
2: strong and weak electricity through optocoupler isolation, safe operation.
3: the power line and the foot switch line adopts the screw free fast connection terminal, more convenient and reliable.
4: input time, current using high-precision single potentiometer, to ensure reliable input, convenient
5: on-board power supply, state, foot, trigger indicator, working state clearly visible.
6: the design of reliable zero crossing detection circuit to ensure that the SCR phase shift accuracy.
7: the controller is compatible with 100A scr.
8: digital control interface, you can display the current time and current settings.
9: time input 1-50, unit cycle (1 cycles is 20ms), current input (30-99%)
If you have other needs, you can customize.
Debugging pictures, we guarantee that every item has to go through the full commissioning, can be issued to everyone.
