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.
