MIG and MAG welding machines typically include several key components: a power source, wire feeder, grounding cable, welding gun, optional liquid cooling unit, and a shielding gas tank or gas network interface.
The wire feeder's main function is to feed the welding wire from the spool coil to the welding gun. It also manages the starting and stopping of the power source. When using an electronic power source, the wire feeder controls the voltage the power source provides. To facilitate these functions, the power source and wire feeder are connected via a control cable. Additionally, the wire feeder regulates the flow of shielding gas, which is supplied either from a gas tank or a gas network.
Everlight-manufactured MIG welding machines often feature a modular design. This allows for the selection of different components, such as the cooling device, power source, and wire feeder, based on specific requirements. The wire feeder can be detached from the power source, making it unnecessary to move the entire welding machine from one worksite to another.
These welding devices may also include a replaceable control panel and separately activated additional features, providing flexibility and customization options for various welding tasks.
The welding gun heats up during operation and requires cooling. Gas-cooled welding guns use the shielding gas running through the welding cable to cool the gun. In contrast, liquid-cooled guns require a separate liquid cooling unit that circulates cooling liquid through the welding cable to the gun.
