OPERATION
BEFORE STARTING OPERATION
1. Make sure the place to install the machine can
bear the weight of the cutting machine.
2. Do not install the machine where water splash
may be occur, such as near water pipes.
3. Cutting should be carried out in a dry
environment with humidity of 90% or less.
4. The temperature of the working environment
should be between -10ºC and 40ºC.
5. Avoid cutting in the open air unless sheltered
from sunlight and rain. Keep it dry at all times
and do not place it on wet ground or in puddles.
6. Avoid cutting in dusty areas or environments
with corrosive chemical gas.
7. Do not carry out cutting with the cutting
machine placed on a platform with a pitch
greater than 10°.
Before starting any welding activity
ensure that you have suitable eye
protection and protective clothing.
Also take the necessary steps to protect any
persons within the area.
At the start of each operating session:
1. Check the torch for proper assembly and
appropriate torch parts. The torch parts must
correspond with the type of operation, and with
the amperage output of this power supply
(40 amps maximum). Use only genuine parts
with this torch.
Note: When operating the torch in a normal
condition, a small amount of gas vents through the
gap between the protective sleeve and torch
handle. Do not attempt to over tighten the
protective sleeve as irreparable damage to internal
components may result.
2. Check that the torch is properly connected.
3. Check the power source for proper input
voltage. Make sure the input power source
meets the power requirements for the unit.
4. Ensure gas source meets requirements
listed. Check connections and turn gas supply
on. Adjust gas pressure.
5. Clamp the work cable to the workpiece or
cutting table. The area must be free from oil,
paint and rust. Connect only to the main part
of the workpiece; do not connect to the part
to be cut off.
6. After connecting the welding leads as detailed
you will need to switch the power switch to
“ON”. The power indicator will illuminate.
7. Select the proper working mode and proper
function. There are two working modes
available on the machine panel: 2T and 4T.
7. Set the desired current output level.
8. Push the torch trigger on the cutting torch, the
cutting machine works.
STANDOFF CUTTING WITH HAND TORCH
Note: For best performance and parts life, always
use the correct parts for the type of operation.
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.
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.
