heavy bead, but does not adhere tightly to the cut
edge, and can be easily scraped off. "High speed
dross" usually forms a narrow bead along the bottom
of the cut edge and is very difficult to remove. When
cutting a troublesome steel, it is sometimes useful
to reduce the cutting speed to produce "slow speed
dross". Any resultant cleanup can be accomplished
by scraping, not grinding.

Standoff Cutting With Hand Torch
NOTE!
For best performance and parts life, al-
ways use the correct parts for the type
of operation.
1. 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 holding 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.
2. 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 stando cuing, hold the torch 1/8 - 3/8
in (3-9 mm) from the workpiece as shown
below.
