• Build Your Own Welder?
• Mig, TIG or arc?

The simplified boards are ready. They work well as it is based on the larger board design.

A manual is in progress. The current version can be found here .

There are 3 switches:

1. Power - turns on/off
2. Remote Voltage - Allows using the local voltage control or a remote wire feeder of foot pedal.
3. Remote Contactor - Allows always on or remote controlled via foot pedal or wire feeder.)

There are two potentiometers (rotary dials):

Voltage - can set the output voltage from 0 to 60 volts.

Current - Sets the current slope an the the current. Set to MAX and the output is constant voltage.

There is a power LED and a remote contactor LED. An output can be used to drive a current meter.

It is relatively simple to use and connect. There are outputs for gas and contactor relays. Main connections for arc welding with an alternator are : Power, Ground, Field +/-, Field Power and the welding voltage and current sense wires.

Ordering:

Note: Boards are currently out of stock. Should have more built in a week or so.

The boards are $70.00 + $5 shipping. To purchase via Paypal, use the "Buy Now" button:

If you would like to use a credit card, but not paypal, send an email to: , Include your address to ship to. I will send a one-time payment link to ProPay.

Above is the board installed in my portable welder. I will print out better dials for the controls and labels for the switches and LED's. The LCD measures the output voltage. I may add a current meter also or wire a switch to select between current/voltage.

The above board is working great. I actually prefer it over the digital one as changes can be done quickly.
