6. Set the gas flow on flewmeter of the gas cylinder, and then open the valve of the torch
7. To boot :
Touch the electrode on
a-
the welding part
8. At end of welding:
Up 2 times the arc (up-down-up-down) to trigger the automatic fade (see paragraph below). This
movement must be performed in less than 4 sec, at a height of 5 to 10 mm. Then close the valve to
stop the torch gas after cooling of the electrode.
Automatic Arc slope with time adjustable
Function activation:
This corresponds to the end of welding time required for the gradual decline in the welding current until the
stop of the arc. This function helps to avoid cracks and craters at end of welding.
1. Press the selector switch
2. Set the automatic arc slope you wish from 1 to 10 sec (display ) using key .
3. Validate the required figure by pressing the selector button

To optimize the working, you have to use an electrode grinded as below:

THERMAL PROTECTION & D
• Thermal protection : thermal protection indicator turns on and the cooling time is about 2 to 5 min
according to external temperature.
• Leave the machine connected to the supply after welding in order to let it cool down
• The welding unit describes an output characteristic of "constant current" type. The duty cycles following
the norm EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below:
