Welding Machine Checklist

By Sam Rawlins

A welding machine is a device used to fuse pieces of metal together, literally melding two pieces into one. Welding machines vary in size, power and electrical output capacities from small, home-use welders to heavy industrial machines. There are different parts for each welding machine depending on the application of the individual tool.

Constant Current

A common type of welding machine uses constant current power. Constant current means the machine holds a fixed current, which is possible through the manipulation of the output voltage. Machines that use constant voltage power, on the other hand, maintain voltage through the output current.

Engines

Many welding machines generate power through basic internal combustion engines. These motors create energy for mechanical functioning. An alternator is used to change the energy into electricity.

Industrial

High-voltage industrial welding machines are called inverter machines. A capacitor inside the inverter takes electricity from a wall outlet and stores high-voltage currents in the machine. The collected energy is then transferred through a microprocessor into currents of a specific output.

Accessories

Other necessary welding machine parts include external clamps for holding loose pieces of metal in place and rolling guides to help roll the metal in a straight line for an even cut. Air regulators and argon regulators are sometimes sold separately.
