Electrode MMA welding (from 10 to 160 A)
•
During this welding type, the welding current is direct.
•
Please follow standard rules for welding.
•
After welding, leave the machine connected for cooling.
•
Thermal protection: the indicator light comes on and cooling time is about 5 min. Your unit is
equipped with 3 special Inverter functions: Hot START gives arcing over- current about 25% more
than the displayed setting; Arc force provides an over-current about 15% more than the setting to
avoid sticking when the electrode enters the bath; and Anti-sticking lets you separate the electrode
easily without reddening in case it sticks.

Maintenance

Make sure the generator is switched off, plug off firstly and wait for the fans to stop. Voltages and
current inside are high and dangerous.
Remove the cover regularly and remove the dust with an air gun.
ENGLISH
In order to weld in this type of welding, you must adjust
the "pulsed" potentiometer between 0.8 and 2.8 Hz
(0.8Hz for a maximum timing between each pulsation
and 2.8 Hz for a minimum timing between each
pulsation).
This type of product is able to do spot welding (potentiometer switch
"pulsed" in position off and potentiometer switch "Down slope" in spot
position). You can work quickly with this mode when you want to spot
the parts to be welded with MIG .
