Arduino Arc Welder That Is Switch Controlled.

An Arduino 2 light arc welder that can be controlled by a mechanical toggle switch or input from an external control circuit.

This concept can also be used with the sketch that runs a welder on a time schedule.  It uses standard LEDS.

There are two other are:

Arc Welder Single Arc That Runs Continuously

Arduino Arc Welder That Runs On Time Schedule

 

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.

 

 

 

 

 

resistorsResistors – Equal to the number of LEDs.

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.

 

In this short video to make the flashing visible have used yellow and blue 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.

Replace the UNO with a nano. Saves you some money.

You may get a cost and time saving Kit to make this at Kits.
