TIG stands for Tungsten Inert Gas Welding and is one of the most common types of welding in the UK.
TIG welding uses a tungsten electrode. Tungsten is non-consumable electrode and has an extremely high melting point. This therefore makes it different to other welding processes as the electrode doesn’t melt and become part of the weld; instead it becomes a part of the filler metal.
TIG welding requires three main components, heat, shielding, and filler metal.
The heat is produced by electricity passing through the tungsten electrode by creating an arc to the metal.
The shielding comes from a compressed bottle of gas that flows to the weld area to protect it from air.
The filler metal is a wire that is dipped by hand into the arc and melted.
What equipment do you need for TIG Welding?
The basic TIG welding equipment components include:
- Tungsten electrode
- TIG Welding machine (constant current-CC, AC, DC+, DC- or AC/DC).
- Torch or electrode holderShielding gas supply (helium, argon or mixture): argon better for thinner metals due to lower heat requirement
- Filler metal rod
- Personal safety equipment
Type of TIG welding Machine
There are advantages to getting a machine that is designed for TIG welding in order to stay balanced during the weld. However, regardless of type, a high-frequency unit must be built-in or attached.
The Welding Superstore stock a wide range of high frequency TIG Welding Machines, from well-known brands like Cemont & Telwin, as well as much more welding technology.
The Telwin 422 offers, high level of control over the welding parameters through easy use control panel. Microprocessor controlled HF (High Frequency) pulsed TIG and MMA welding machine, in DC (Direct Current) and AC (Alternating Current). Suitable for use with a wide range of materials such as Steel, Stainless Steel, Titanium, Copper, Nickel, Aluminium. With the ability to save jobs and quickly change between jobs using the control panel this machine is suitable for maintenance, and production welding to a high level.
The SIP 05775 inverter welder has the capabilities of welding steel and stainless steel. With dual weld TIG and ARC functions this welder has a DC output current requiring a 230v (16amp) supply.
