My Miller TIG torch has an adjustable amperage button and on/off button built into the handle. This comes in handy when on the ground and welding above your head. I like to use the foot pedal as much as possible because of greater control, but I do recommend that you use the on/off button on the torch with the foot pedal disconnected to learn the basic movement and speed. Most people find that when the foot pedal is out of the mix they can focus on movement and not on what to do with their foot and both hands.
