MIG Controller
The purpose of this project is to control a traditional transformer based mig welder and add "useless" features.
It has "useless" features such as:
- Voltage Read Out
- Current Read Out
- Spot Weld Control
- Pulse Weld Control
- Wire feed units 1
- Run in speed
- Burn back
- On delay
- Off delay
- Gas pre flow
- Gas post flow
- Motor reverse
- Persistant settings
- Thermal cut off
The majority of above are customizable through the display menus and rotary encoder.
Main hardware requirments:
- Arduino Uno or other compatable micro controller
- H-Bridge motor driver 3 pin control
- HD44780 16x2 Display
- Solid State Relay
- Push button rotary encoder
- Power Supplies for H-bridge driver and microcontroller
1 Full configuration of the wirefeeder will require testing and reprogrammnig of the microcontroller.
