6. OPERATION
WARNING! If you have no welding experience, we recommend
you seek supervised training from an expert source.
6.1.
Introduction. Your welder features a single phase transformer with a
drooping characteristic suitable for welding with an alternating current
using stick electrodes with diameters from 1.5mm to the highest
electrode diameter as shown on the chart in Fig.6.
6.2.
Current regulation. The intensity of the welding current can be
adjusted by means of a manually operated magnetic shunt. See Fig.1-3.
To increase the current turn the knob clockwise whilst making reference to the graduated scale on the top of the machine (See Fig.3).
To decrease the current turn the knob anti clockwise. Note: Set the current to the desired level before commencing welding.
DO NOT operate the current regulation mechanism whilst welding is in progress.
6.3.
Thermostatic Protection.
6.3.1. Temperature Control Indicator Light.
When the machine is overheating, it cuts off the power and the indicator light comes on. When the temperature has dropped to the
recovery temperature, the machine can automatically restart and the indicator light will go off.
See Fig.1-5.
6.3.2
Temperature Protection Indicator Light.
If the Temperature Controller fails, the protector will cut off the power and the indicator light comes on. Temperature protection can not
resume automatically. If needed, please follow the methods below for recovery operations:
1. Turn off the machine's power.
2. Open the cover of the machine.
3. When the temperature protector pops up on the red contacts, such as in the picture right,
off.
4. Press the red contacts on the thermal protection
welding rods you may experience a temporary current shut off. The larger the welding rod, the greater the current required,
consequently, the hotter the machine will become and the quicker it will cut out.
6.4.
Setting up the welder.
6.4.1. Ensure the machine is turned off from the mains power supply. (See fig.1-2).
6.4.2. Attach the earth clamp to a point on the workpiece that has been cleanly ground to provide good contact.
Attach it as close as possible to the area you will be welding.
6.4.3. Select the diameter of electrode to be used in relation to the type of weld to be made. Consideration should
be given to the fact that higher current values should be used for flat welding, whereas for vertical or over
head welding lower current values are required. Insert the electrode into the electrode holder. Ensure there is
a good connection. Ensure welding surfaces are kept clean and free from grease, or oil.
6.4.4. Establish the welding current required in relation to the diameter of electrode you are using by making reference to
the table in Fig.6.
6.4.5. Set the current required in amps using the control knob on the front panel. See Fig.1-3. The current set
can be read from the graduated scale on the top of the machine. See Fig.3.
6.5.
Commencing Welding It is advisable to practice on scrap metal first, especially where potentially difficult
welds are to be undertaken.
WARNING! Remember to wear a full face welding mask, gauntlets and protective clothing and
ensure you have read, understood and apply safety instructions. Wear goggles whilst chipping
slag.
6.5.1. DO NOT switch on the power supply until you are fully ready to start welding.
6.5.2. Place the face mask in front of your face.
6.5.3. To strike the arc tap the electrode lightly on the workpiece as if striking a match. DO NOT hit the
electrode on workpiece as this may damage the stick.
