The system includes an automatic gas and power shut down that activates if the TIG output remains energised for too long without welding. Preventing unnecessary gas use and enhancing operator safety.\u003c\/p\u003e\n\u003cp data-start=\"637\" data-end=\"997\"\u003eA fan on demand circuit ensures the cooling fan only runs when needed, reducing noise, dust intake, and component wear. During the welding process, the output automatically resets to off during slope down if the arc is interrupted, while the upslope timer only begins once the arc is initiated, giving you precise, controlled starts every time.\u003c\/p\u003e\n\u003cp data-start=\"999\" data-end=\"1275\"\u003eFor additional safety, the output power always remains off when the machine is switched on until the torch trigger is pressed or MMA mode is selected.
