When this controller is running a bead, the workflow is simple: pressing the switch strikes the arc, and sliding the lever sets the amperage level. The setting stays where you leave it without continuous finger pressure, and sliding back or clicking the lever ramps the current down and ends the arc. That covers the whole arc cycle with one hand on the torch.
The maker, 6061, designed and built this remote amperage control and switch, called the Slide-Lever, and it mounts directly to a TIG torch handle. The textured sliding plastic lever attaches with a zip tie and a velcro strap, and a dedicated multi-pin control cable runs back to the welding power supply. Finger rest contours and trimming provisions let it fit both round torches and flat D-handles, which seems like a practical way to cover the handle shapes people actually own.
Two numbers stand out to me. The design sits half an inch lower than other torch sliders, and the travel stroke is 15 mm shorter. Combined with the short throw, that should mean less finger movement per adjustment, though that is my read rather than something measured here. The demonstration welds are serious too: multiple aluminum passes on straight fillets, outside corners, and curved lap seams, including 1/4-inch plate, with bead consistency and clean arc restarts at fixed amperages. Panel readings of 87 A, 225 A, and 100 A back that up.
One open point: compatibility is demonstrated on PrimeWeld and Miller power sources, so how it behaves with other brands is not shown. The maker also explains cable routing and slack management inside the torch zippered sheath, and offers assembled cables and tutorials on their website.
