An Arduino 2 light arc welder that can be controlled by a mechanical toggle switch or input from an external control circuit.
The sketch is versatile. It is easily amended to control multiple arc welders
About This Arc Welder
You may want the arc welder to show either on demand or have it automatically timed using a daily schedule controller which controller is on an external Arduino.
The sketch for this arc welder is on Pastebin at Arc Welder Toggle Controlled. –
Materials Required
Arduino Nano – You may also use an UNO
LEDs – The basis welder uses two white. We show yellow here so that you can see it against the white background.
You may increase the number or LEDs and/or change the colors.
Resistors – Equal to the number of LEDs.
Prototype Board – i piece
Kit
All the parts shown are readily available. For your your convenience, however, You may get a cost and time saving kit to make this at Kits.
Arc Welder Demonstration
In this short video to make the flashing visible have yellow LEDs . We normally use white. Some folks use a blue marker to cover part of the LEDs with blue.
You may also add a third LED.
The video doubles as a wiring diagram.

The code simulation was made using WOKI. It is a great tool, resource and help center.
Wiring Diagram
It is important to remember to add resistors on the anodes of the LEDs.
Getting Parts
Getting parts can take a lot of time if you get them from the Far East, assuming you get good quality, or they can be rather expensive it you buy them one at a time. Kits are cost saving and everything comes to you at once. And these are shipped Europe and the US. And the materials have been approved for quality. Look at them at This Page.
Arc Welder Library
There are all the arc welder sketches available.
Arc Welder That Runs Continuously – Simple but effective and easily modified.
Arc Welder Switch Controlled. – Turns welder on and off using a simple toggle switch.
Arc Welder Timed Operation – The arc welder will start and stop on a time schedule that you set.
