TIG welding is a precise and versatile technique used to join metals together. It involves using a non-consumable tungsten electrode and a shielding gas to create a high-quality weld.
There are two main types of TIG welders: inverter welders and transformer welders. Inverter welders use advanced electronics to convert AC power to DC, resulting in a more efficient and portable machine. On the other hand, transformer welders use a transformer to step down the voltage for welding. They are generally heavier and less portable than inverter welders.
TIG welders consist of several key components:
- Welding torch: This handheld device holds the tungsten electrode and directs the shielding gas.
- Power source: This unit supplies the electricity for the welding arc.
- Gas cylinder: This container stores the shielding gas.
- Foot pedal: This controls the welding current and is often used for precise control.
