Category Operation & Starting Method

Run clean, dry air and set the regulator with flow on. Attach the work lead to bright metal, install fresh consumables, and power on. For pilot-arc torches, let the pilot establish, then move to the work to transfer; for contact-start, touch the shield to the edge to strike and lift to cut height. Start from an edge when possible; for pierces, use the charted pierce height/delay, hold vertical, and begin with a short lead-in. Maintain cut height with a drag shield, stand-off gauge, or THC and keep a steady travel speed—look for even drag lines and minimal dross. At cut end, pause briefly, overlap 1–2 mm, then let post-flow cool the torch.
