6. ASSEMBLING THE
WELDER
Make sure the power supply information on the
machine’s rating plate is compatible with the power
supply you intend to connect it to.
A suitable plug must be fitted by a qualified
electrician.
This machines wiring has insulation stripped in
preparation for wiring a 32A plug (not supplied).
It is designed for connection to a 32amp
power supply
rated at 230V AC.
Because it is constructed mostly of metal parts, it is a
Class 1 machine; meaning, it must have an earth
connection in the power supply. This is to prevent
electrocution in the event of a failure.
Note: Remove the plug from the socket before carrying
out adjustment, servicing or maintenance.
Check that the electrical supply delivers the voltage and
frequency corresponding to the welding machine and
that it is fitted with a delayed fuse suited to the maximum
delivered rated current.
Note: The welding machines are set to the highest
voltage at the factory.
7. SETTING THE WELDER
7.1 GENERAL
This highly developed multifunctional welder is suitable
for electrode arc welding, flux-cored wire welding (no
gas ) and solid wire welding (with gas). Able to work
continuously and can balance automatically when
voltage is waving.
7.2 LOCATION
Locate the machine close to the correct power supply
and allow a 500mm air gap around to ensure sufficient
ventilation. There are two cooling fans located in the rear
of the machine housing which must be kept clear.
Equally, ensure no debris can be drawn into the
machine.
Make certain the location does not pose any hazards as
detailed in the safety instructions, before attempting to
start the machine.
Note: Refer to the rating label for energy input details.
For MIG operations, ensure the gas bottle is securely
mounted and in a vertical position according to the
manufacturer’s instructions.
WARNING: Remove the plug from the socket before
carrying out adjustment, servicing or maintenance.
7.3 MMA (MANUAL METAL ARC)
To attach the electrode holder
(16)
to the front panel,
insert the plug into positive coupling
(11)
and twist
clockwise to lock.
Attach the earth clamp
(15)
to the negative coupling
(13)
and twist clockwise to lock.
7.4 INSTALLING THE FILLER WIRE
(MIG WELDER) – FIGS. 1 - 5
The welding machine is designed to accept the standard
size drums of wire (5kg).
The welding wire can be either of the flux-cored types
this provides a means of shielding the weld pool from the
atmosphere.
Or non-flux wire with the gas hose connected to the back
of the machine.
Do not let the filler wire become uncoiled or tangled as
this will lead to problems with delivery to the welding
torch.
Select the filler wire suitable for the parent metal and
with a gauge to match the welder specification.
Note: If the welding machine is not regularly used,
remove the wire which is prone to rust and will cause
feed problems next time.
1. Lift the catch
(22)
on the side panel and swing open
the cover up onto the top.
2. Unscrew the large plastic ring. Sit the reel on to the
hub
(20)
and make sure the peg locates in the back
of the reel. Refit the large plastic ring.
3. Fit the wire spool so that it feeds off the base of the
reel towards the wire drive unit
(21)
.
4. Pull tensioner
(21.1)
forward off the tension arm
(21.2)
, the tension arm
(21.2)
will spring up out of the
way.

5. The wire must sit in the appropriate groove for the
wire gauge. The groove size is etched on the side of
the roller. Remove nut to see the groove size that is
NOT in use. The drive roller
(21.4)
can be removed
from shaft, to change the groove size for appropriate
wire gauge. Unscrew and remove the retaining cap.
6. Pass the filler wire through the guide
(21.3)
and over
the top of the drive roller, make sure the wire is well
inside the torch liner before closing the arm
(21.2)
