 Torch-to-work standoff / arc stretch – Move the torch away from the workpiece to make
the gouge wider, shallower, and smoother on the bottom . Move the torch closer to the
workpiece to make the gouge narrower and deeper .
 Arc stretch is related to the output current (A) of the plasma power supply. The higher
the amperage, the longer that you can stretch the arc. Hypertherm recommends that you
keep amperage and arc stretch consistent.
 Keep at least a small distance between the torch tip and the molten metal to increase
cartridge life and prevent damage to the torch.
 Speed of the torch – Increase the speed of the torch movement to make the gouge
narrower and more shallow . Decrease the speed of the torch movement to make the
gouge wider and deeper .
