having care to ascertain that the cabinet or the stocked accessories are not damaged.
Your welder is capable of daily activity of construction and reparation. Its simplicity and versatility and its
excelling welding characteristic are granted by the inverter technology. This welding inverter allows to be
finely set to obtain optimal arc characteristics with a reduced consumption of energy with respect to the
welders based on a traditional transformer.
Respect the duty cycle of the welder making reference to the technical data label on the welder's back.
Duty cycle is given as percentage on a 10 minute time. During this period of time the unit can be used at
a defined power regulation. Duty cycle exceeding may cause overheating or welder's damage.
Welder's basic specifications:
4.0
Your welder offers two welding functions in the same generator. These functions can be selected thru the
selector key on the front panel of the unit:

we can weld rutile electrodes till diam. 3,25mm. The welding current is adjustable thru the potentiometer
on the front panel.
MIG (GMAW and FCAW) Welding with Gas and without Gas
This welder offers the chance to weld in manual function allowing to the operator the possibility of setting
