Simple welding production circuit

Published on Mar 16 2011 // Instrumentation and Tester Circuits

Model aircraft and jet engines in the production process may take a welding machine, welding stainless steel if he could buy if the price of 1,000 yuan or more, then Can I own one, of course you can; price, but more than 100 points, do not welding.
Materials needed
A small 220v power adapter, 300w or more, the bigger the better, the price of about 100
Relay A
A micro switch
Two brass rod
Welding capacity
1.5mm +1.5 mm steel, aluminum, stainless steel
Circuit diagram ( 220V AC danger! Please pay attention to safety!!!! )

Simple welding production circuit

Production Method
  220v transformer secondary will not have the original, and the other to buy 2m more than 0.5 square centimeters thick wire in the transformer secondary Shangrao 6T done, measuring the output voltage is 4v can, click the image connected to the relay, and micro switch, do a good job the two welding electrodes. Click the image can be installed.
