and can often be wiped off with a welding glove.
"Slow speed dross" is normally present on the bottom
edge of the plate. It can vary from a light to 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 parts performance and life,
always 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 con-
tact with the workpiece except dur-
ing 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 standoff cutting, hold the torch 1/8 - 3/8
in (3-9 mm) from the workpiece as shown
below.
