PlASMA ARC CAN CAUSe INJURy ANd bURNS
Plasma arc comes on im me di ate ly when the torch trigger is activated. The plasma arc will cut quickly
through gloves and skin.
• Keep away from the torch tip.
• Do not hold the workpiece and keep your hands clear of the cutting path.
• Never point the torch toward yourself or others.

The T45v is equipped with a safety trigger to prevent accidental firings. When you are ready to cut with the torch, flip
the yellow safety trigger forward (toward the torch head) and press the red torch trigger as show below.
Hand torch cutting hints
• With shielded consumables, drag the nozzle lightly along the workpiece to maintain a steady cut. With unshielded
consumables, maintain an approximate 2 mm (0.08-inch) distance between the tip of the torch and the workpiece.
(This is between 1.6–3.2 mm, or between 1/16th and 1/8th of an inch.)
• While cutting, make sure that sparks exit from the bottom of the workpiece. The sparks should be lagging slightly
behind the torch as you cut (15° – 30° angle from vertical).
• If sparks are spraying up from the workpiece, move the torch more slowly, or set the output current higher.
