A 3 phase welder is a type of welding machine designed to operate on a three-phase electrical power supply, commonly used in industrial settings.

3 phase welders are versatile tools for various welding applications, favoured by industrial and professional users for its consistent and powerful performance. Unlike single-phase power, typically used in residential settings, three-phase power is more efficient for high-power electric motors such as those found in 3 phase welders. This makes 3 phase welders ideal for commercial welding applications that require consistent and robust power output.

Large-scale fabricators such as automotive, shipbuilding, and construction industries typically utilise 3 phase welders for their high-volume welding needs. Many manufacturing plants and workshops use 3 phase welders because of the consistent power they offer. Fabricators who offer specialised services, like pipe welding or structural steel welding, often prefer 3 phase welders for their robust performance. Welding training centres and technical colleges might also employ 3 phase welders for training students, giving them a feel for industrial-grade equipment.

3 Phase Welder Fabrication Types:

MIG welding is a semi-automatic or automatic arc welding process wherein a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. This method is popular due to its versatility and speed.

This is similar to MIG, but instead of solid wire, it uses a tube filled with flux. It’s particularly suited for thick materials and outdoor welding, as the flux provides its own shielding, negating the need for external gas.

TIG welding uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas. It’s known for creating strong, high-quality welds but requires a higher skill level than MIG.

In arc welding, an electric current is used to strike an arc between the base material and a consumable electrode rod or “stick”. The electrode’s core itself provides the filler metal.
