What should we consider when choosing a welding machine?
Welding machines, or welding guns, are one of the most essential tools for a welder. Welding machines generate heat that melts metal parts so that they can be joined together.
They are designed with a wire welding electrode on a spool that is fed at a pre-selected speed through a welding gun. As a semi-automatic or automatic process, gas metal arc welding is the easiest to learn.
There are several models of welding machines, each of which serves a different purpose.

Types of welding equipment
- Stick Welding/SMAW - Stick welding uses an electric current that flows through the gap between the metal and the welding rod (arc welding electrode).
- MIG WELDING/GMAW -This technique uses a wire welding electrode on a coil that is fed at a constant speed. An arc is created by an electric current between the base metal and the wire.
- Flux Cored Arc Welding- This process also uses a wire electrode that is continuously fed, although it does not require a shielding gas. The flux cored wire shields the arc.

Choosing welding equipment for beginners
If you're new to welding, the wide range of products on the market can be overwhelming at first.
There are versatile, multi-process machines that can weld with more than one welding process. There are also engine-powered (fuel-powered) welders for operation from the electrical grid.
The following are the machines recommended for beginners:
- Metal Inert Gas (MIG)
- Tungsten Inert Gas (TIG)
- Shielded metal arc welding (SMAW or stick)
- Oxy-acetylene welders (<gas> or <oxy-fuel>)
