MMA WELDING
4.1.1. Connect the electrode holder and earth clamp correctly (fig.3).
4.1.2. Plug in the power supply and turn on the switch.
4.1.3. Select to MMA function.
4.1.4. Turn ON/OFF the VRD function accordingly.
NOTE: Turning on the VRD function can prevent accidental electric shock caused by touching the positive and negative output
terminals simultaneously. It is recommended to turn on this function.
4.1.5. Set the current according to the thickness and electrode diameter.
4.1.6. Start welding.

MMA WELDING - ALKALINE & ACID ELECTRODES (FIG.3)
MMA (Manual Metal Arc) welding, also known as stick welding, can be performed using both alkaline and acid electrodes. The choice
between them depends on the specific welding application and the type of material you are working with.
4.2.1. Alkaline Electrode Connection
Alkaline electrodes are typically used with basic or alkaline-coated welding rods. These rods have a basic or high-cellulose coating,
which stabilizes the welding arc and produces a smoother weld bead. Alkaline electrodes are often preferred for welding thicker metals
and in situations where a strong, stable welding arc is required. They are suitable for applications where the appearance and quality
of the weld are important. Alkaline electrodes are usually connected to the positive terminal (DC+ or reverse polarity) for better arc
stability.
4.2.2. Acid Electrode Connection
Acid electrodes are used with rutile-coated or acid-coated welding rods. These electrodes offer good penetration and are versatile
for various welding tasks. Applications: Acid electrodes are suitable for general-purpose welding and can be used on a wide range of
materials. They are often chosen for their ease of use and versatility. Acid electrodes are typically connected to the negative terminal
(DC- or straight polarity) for optimal performance.
The choice between alkaline and acid electrodes and their corresponding electrode connections should be made based on the
specific welding requirements and the materials being joined. It's essential to follow the manufacturer's recommendations for electrode
selection and polarity to achieve the best welding results. Additionally, proper welding techniques and safety precautions are critical for
a successful welding operation.

BATTERY CHARGING
4.3.1. Plug in the power supply and turn on the switch.
4.3.2. Select the charger function, then select the charging function (fig.2).
4.3.3. According to the nominal voltage, select the correct output voltage (12V or 24V).
4.3.4. Connect the red charging clip to the red output port (positive), and the black charging clip to the black output terminal (negative).
Connect the red charging clip to the positive pole (+) and the black charging clip to the negative pole (-).
4.3.5. Press the "accept" button to start charging
NOTE: The battery terminal not connected to the chassis has to be connected first. The other connection is to be made to the chassis,
remote from the battery and fuel line. The battery charger is then to be connected to the supply mains.
4.3.6. After Charging, disconnect the battery charger from the supply mains. Then remove the chassis connection and then the battery
connection.
