Resistance Soldering Machines

The machine is widely used for carrying out resistance welding process. Resistance welding is a technique, in which heat required to melt solder is acquired directly by passing a high amperage electrical current through a resistive material.

Soldering Process
In resistance soldering, a pair of carbon electrodes is used to generate the heat that holds the metal area to be welded. The electrical current is carried on from one electrode to one electrode through the metal and then into the other electrode. The passage of current leads to heating of the metal.

Basically, there are three components of resistance welding machine :

• A resistive material to generate the heat
• A specialized step-down transformer that will generate the appropriate current
• Ability to complete an electrical circuit

Benefits of Resistance Welding Machine
There are various advantages of using resistance welding machine. Some of them are :

• The machine can be used to eliminate a flame hazard and oxidation
• The machine can be used in conditions which requires restricting heat to a limited portion of the surface
• Ideal for conditions where the port is inaccessible for soldering irons
