Image: Detailed TIG welding cycle diagram showing adjustable parameters.
- Pre-flow: Time for shielding gas to flow before arc ignition.
- Post-flow: Time for shielding gas to flow after arc extinction to protect the weld puddle.
- Up Slope: Time taken for the welding current to increase from start current to peak current.
- Down Slope: Time taken for the welding current to decrease from peak current to finish current.
- 2T/4T: Trigger modes for torch control. 2T (2-touch) requires holding the trigger; 4T (4-touch) allows for continuous welding without holding the trigger.
- Kekerapan AC: Adjusts the number of times the AC current changes direction per second, affecting arc focus and penetration.
- Baki AC: Controls the cleaning action and penetration when welding aluminum.
- nadi: Adjusts pulse frequency and duty cycle for pulsed welding modes.
