• Standoff Cutting With Hand Torch
NOTE
For best performance and parts life, always
use the correct parts for the type of opera-
tion.
A. The torch can be comfortably held in one
hand or steadied with two hands. Position
the hand to press the Trigger on the torch
handle. With the hand torch, the hand may
be positioned close to the torch head for
maximum control or near the back end for
maximum heat protection. Choose the hold-
ing technique that feels most comfortable
and allows good control and movement.
NOTE
The tip should never come in contact with
the workpiece except during drag cutting
operations.
B. Depending on the cutting operation, do one
of the following:
a).
For edge starts, hold the torch
perpendicular to the workpiece with
the front of the tip on the edge of the
workpiece at the point where the cut is
to start.
b). For standoff cutting, hold the
torch tip on the work piece, pull the trig-
ger. After the arc is initiated lift the tip to
1/8" - 3/8" (3-4mm) off the work.
