Operation
Before starting any cutting activity ensure that you have
suitable eye protection and protective clothing. Also take
the necessary steps to protect any persons within the
area.
Check that all connections have been made as shown above
Check the following before starting the machine.
1)
Check if the machine is reliably grounded according
to the relevant standard.
2)
Check that there are no bad contacts.
3)
Check if the power cord is connected to the correct
input voltage.
4)
Check if the connecting cables and gas hoses are in
good condition and are not twisted.
Operation
1)
Turn on the power switch on the back panel of the
machine, and the power LED is on.
2)
Select the working mode and function. There are two
working modes available on the machine panel: 2T and 4T.
There are two functions available: normal cutting and metal
mesh cutting. The electrode and nozzle wear is increased in
metal mesh cutting.
3)
Set cutting current according to the thickness of
workpiece.
4) Bring the copper nozzle of the cutting torch at a distance
of about 2mm between the copper nozzle of the torch and
the workpiece.), and then push the torch trigger. After the
arc is ignited and cutting starts.
5) It is recommended that a torch of maximum length of 4
metres is used. If the torch cable is too long, the
performance of this cutting machine such as arc ignition
will possibly be a
ff
ected due to the fact that the inner
resistance of the cable will reduce the output voltage.
Notes for cutting operation
1)
Do not touch the hot workpiece with bare hands to
avoid burning.
2)
It is recommended not to ignite the arc in the air if not
necessary, for it will shorten the lifespan of the electrode and
nozzle of the torch.
3)
It is recommended to initiate the cutting from the
edge of workpiece, unless penetration is needed.
4)
Ensure spatter comes from the bottom of workpiece
while cutting. If spatter comes upward from the top of
workpiece, it indicates that the workpiece has not been fully
cut through. This could be due to not enough power or the
cutting torch is moved too fast.
5)
For cutting a round workpiece or to meet precise
cutting requirement, a stencil board or other tools are
needed.
7)
It is recommended to pull the cutting torch while
cutting.
8)
Keep the nozzle of cutting torch upright over the
workpiece, and check if the arc is moving with the cutting
line. Do not bend the cable too much, step on or press upon
the cable to avoid restricting the air flow. The cutting torch
may be burned if the air flow is too low. Keep the cutting
cable away from sharp edges.
9)
When the workpiece is nearly cut o
ff
, slow down the
cutting speed and release the torch trigger to stop cutting.
10)
Maintain the torch consumables frequently to prolong
the life
6) Always ensure the correct consumables are fitted in the
torch. Incorrect items may cause damage to the torch or
machine
