To generate an arc in a TIG welding machine setup, follow these steps:
1. Power Supply: The TIG welding machine is connected to a power supply, which provides the necessary electricity for the welding process.
2. Gas Supply: A gas cylinder containing a shielding gas, such as argon or helium, is connected to the TIG welding machine. This gas protects the weld pool from atmospheric contamination during the welding process.
3. Torch: The TIG welding torch is connected to the machine and is equipped with a tungsten electrode. The torch also has a gas nozzle through which the shielding gas flows.
4. Ground Clamp: The ground clamp is connected to the workpiece to complete the electrical circuit.
5. Foot Pedal or Torch Switch: The TIG welding machine is equipped with a foot pedal or torch switch that controls the flow of electricity to the torch.
6. Arc Starting Procedure:
a. Turn on the TIG welding machine and set the desired welding parameters, such as amperage and gas flow rate.
b. Press the foot pedal or torch switch to initiate the flow of shielding gas.
c. Bring the tungsten electrode close to the workpiece and press the foot pedal further to initiate the flow of electricity.
d. As the electrode approaches the workpiece, an arc is generated between the electrode and the workpiece.
e. Maintain the arc length and move the torch along the joint to create a weld bead.
By following these steps and maintaining proper technique, a stable arc can be generated in a TIG welding machine setup.

TIG Welding Machine Setup

Procedure for Generating an Arc:
1. Prepare the workpiece: Clean and grind the surface of the workpiece to remove any dirt, rust, or impurities.
2. Set tungsten electrode: Insert the tungsten electrode into the torch head and adjust its length to approximately 1/4 inch (6.35 mm) beyond the nozzle. Ensure the electrode is clean and sharpened to a point.
3. Connect the welding cables: Connect the torch lead to the negative terminal (electrode) and the ground clamp to a clean metal surface on the workpiece.
4. Adjust shielding gas flow: Turn on the gas regulator and adjust the flow rate to the recommended level for the welding material being used. This is typically 15-25 cfh for argon.
5. Initiate the arc: Tap the tungsten electrode lightly against the workpiece to initiate an arc. The electrode should not stick or "freeze" to the workpiece.
6. Hold the torch: Hold the torch at a slight angle to the surface of the workpiece, approximately 1/8 to 1/4 inch (3.2 to 6.35 mm) away. Maintain a steady hand motion during welding.
7. Feed filler metal: If required, feed filler metal into the weld pool using the left hand. Hold the filler metal at a slight angle to the weld pool and feed it into the arc in a controlled manner.
8. Control arc length: Adjust the distance between the tungsten electrode and the workpiece to maintain a stable and consistent arc length. The arc length should be slightly longer than the diameter of the tungsten electrode.
9. Maintain arc shielding: Ensure that the shielding gas is flowing continuously around the weld pool to prevent oxidation and contamination.
