The high reactance type 2. The joining of two metals at room temperature with the application of a large amount of pressure is called cold pressure welding.
The welder welding machine is either electric- or motor-powered.
. That the OCV of welding machines is low enough to prevent easy passage of current through the body. These machines are available in different sizes as per their utility. Basic Types of Welding Transformers.
Typical uses for this welding machine. The welding offered is sturdy strong which can withstand enormous force. It is popular welding because of its low cost easy and simple operability.
