TIG Welding Machine; What it is and How it Works

TIG (Tungsten Inert fuel) welding is a technique that uses an electrically powered arc to sign up for metallic collectively. A famous welding method produces excellent welds with a smooth and precise end. TIG welding is used in various industries, including aerospace, car, and manufacturing. To carry out TIG welding, you need a TIG welding gadget.

In this article, we can discuss what a TIG welding gadget is, how it works, and the different types available.

What’s a TIG Welding system?

A TIG welding device is a device that provides the strength and control essential for TIG welding. An electrical gadget generates an electric arc between the tungsten electrode and the workpiece. The gadget regulates the contemporary gasoline float and electrode feed to supply significant welds.

How does it paint?

A Tig welding machine generates a high-frequency AC or DC cutting-edge that flows via the tungsten electrode and the workpiece. The tungsten electrode is in a torch, and the workpiece is in a clamp. The electrode isn’t fed on for the duration of welding, and it is surrounded utilizing inert gasoline that protects the weld pool from contamination.

When the arc is hooked, the welder feeds a filler rod into the weld pool to join the two metallic pieces. To supply a clean and specific weld, the welder controls the welding velocity, current, and fuel float.

Sorts of TIG Welding Machines

Specific varieties of TIG welding machines are available, and they range in their strength supply and capabilities. Right here are the three most commonplace forms of TIG welding machines:

AC TIG Welding Machines

Those machines use alternating present-day (AC) to supply the welding present-day. They are suitable for welding aluminum and different non-ferrous metals. AC TIG welding machines are extra highly-priced than DC TIG welding machines and require a high-frequency generator to begin the arc.

DC TIG Welding Machines

Those machines use direct modern-day (DC) to provide the present welding day. They’re suitable for welding ferrous metals, which include metal and chrome steel. DC TIG welding machines are much less steeply-priced than AC TIG welding machines and do not require a high-frequency generator.

AC/DC TIG Welding Machines

These machines can transfer among AC and DC modern-day, making them suitable for welding each non-ferrous and ferrous metals. AC/DC TIG welding machines are the most versatile and expensive sort of TIG welding machine.

Capabilities to recollect when choosing a TIG Welding system

When selecting a TIG welding system, there are numerous capabilities not to forget, consisting of:

1. Electricity

The power output of the machine will determine its welding capacity. Higher energy output machines can weld thicker substances.

2. Duty Cycle

The duty cycle is when the device can constantly weld earlier than it wishes to settle down. Machines with a better obligation cycle can weld for more extended periods.

3. Manage Panel

The control panel must be easy to apply and offer unique control over the welding parameters.

4. Portability

If you want to transport the device frequently, recollect a lightweight and portable system.

5. Rate

TIG welding machines can range from some hundred to several thousand bucks. Take into account your price range while choosing a system.


A TIG welding gadget is a vital device for TIG welding. It gives the power and manipulation essential to provide significant welds. While deciding on a TIG welding device, remember the type of modern-day electricity output, responsibility cycle, manipulate panel, portability, and rate. You can perform TIG welding readily and with self-assurance by selecting the proper machine.
