Grounding
Grounding clamp (5) must be connected to the workpiece or the metallic surface on which the
piece is positioned.
Check for direct contact with the workpiece
Avoid painted surfaces or isolated.
Electrode
Before striking an arc, insert an electrode in the electrode holder (4). A small diameter
electrode requires less current than a large one. Follow recommendations of the electrode
manufacturer when setting weld amperage.
Switching On and OFF:
to start the machine press switch (2) in position “ON”. The cooling fan
will start .
Setting weld amperage
Select welding current with button (3) depending on the electrode diameter
Ø electrode [mm]
Welding amperage [A]
1.6
50-80
2
60-90
2.5
80-110
3.2
100-130
4
130-160
Overheat protection
If the indicator (1) lights, the thermal protection is activated . If the cycle work displayed on the
plate is exceeded, the device will stop working before it causes other damage. Wait until the light
stops flashing light to resume operation.If further thermal protection is triggered, it means the
machine is used over its standard performance
Welding
To start the welding arc with a covered electrode, gently touch the work piece and as soon as
welding arc starts, keep constant distance from the working piece (equal with electrode diameter)
at an angle of 20-30 ° in the welding direction. A short arc with correct amperage will give a sharp
sound.
Slag
Slag removes only after cooling Use a chipping hammer and wire brush to remove slag. Remove
slag and check weld bead before making another weld pass.
Cleaning and maintenance
Before performing any work on the equipment, pull the power plug.
Cleaning
To avoid fire due to damage of electrical wiring insulation, remove dust after welding
operation. When cast metal dust inside the housing, switch off and disconnect the equipment
from power supply, then clean it with compressed air.
