04 Hand Torch Operation - ESAB Cutmaster 60 Manual De Instrucciones

Direction of Cut
In the torches, the plasma gas stream swirls as
it leaves the torch to maintain a smooth column
of gas. This swirl effect results in one side of a
cut being more square than the other. Viewed
along the direction of travel, the right side of the
cut is more square than the left.

Side Characteristics Of Cut
To make a square - edged cut along an inside
diameter of a circle, the torch should move
counterclockwise around the circle. To keep
the square edge along an outside diameter cut,
the torch should travel in a clockwise direction.
Dross
When dross is present on carbon steel, it is
commonly referred to as either "high speed,
slow speed, or top dross". Dross present on top
of the plate is normally caused by too great a
torch to plate distance. "Top dross" is normally
very easy to remove and can often be wiped off
with a welding glove. "Slow speed dross" is nor-
mally 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.

OPERATION
ESAB CUTMASTER 60
NOTE!
For best performance and parts 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 contact
with the workpiece except during
drag cutting operations.
2. Depending on the cutting operation, do
one of the following:
a. F o r e d g e s t a r t s , h o l d t h e t o r c h
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.
