For MMA welding
Connect the electrode holder to the positive (+)
output terminal
8
and the work return lead
should be connected to the negative (-) output
terminal
7
.
Switch the machine on using the on/off switch
1
at back of machine, the power indicator light
3
will
illuminate. Then turn machine on by pressing the
power button
6
on the front.
Choose the correct electrode diameter for the job.
Adjust the electrode diameter knob
2
to suit
electrode used.
The machine will stop working if the temperature
reaches a certain level. (Exceeds the unit's duty
cycle). The overtemperature control indicator light
4
will illuminate.
NOTE:
When changing the MMA electrode holder the machine should be
switched off using both the on/off switch on the back and the power
switch on the front of the machine. In addition, the main supply must
be turned off and the plug removed from the outlet socket.
4.1 Operating Machine
•
Select the electrode diameter by adjusting the
electrode diameter knob
2
.
•
Select the polarity of the electrode cable as per
the recommendations (+/-)
4.2 Earthing
•
For the welding process to be most effective
it is important to ensure that there is a solid
connection between the work return clamp and
the workpiece.
•
Always ensure that the return clamp is as close as
practically possible to the area to be welded.
•
Ensure that the workpiece is clean and free from
rust, scale paint or oil and grease before affixing
the work return clamp.
4.3 Machine Fan
•
The fan will begin to operate when the internal
temperature of the machine reaches above 45°C.
This fan will stop once the temperature is less
than 35°C
