This welding machine is manufactured with advanced inverter technology. With power component
MOSFET and PWM technology, the inverter converts DC voltage, which is rectied from input
AC voltage, to high 100KHz frequency AC voltage; as a consequence, the voltage is transformed
and rectied. Therefore, it results in a smaller transformer and lighter inverter machine, which
increases welding performance by 30%. The high frequency oscillation, which enables the output
of high frequency DC, is employed in the arc-starting system. The features of this product are as
follows: stable current, reliable, fully portable, ecient and quiet in operation.
When MMA welding, this welding machine features stable output and the option of arc force.
In case of normal arc input voltage, the stability of welding current output is not compromised
with variation of arc length, therefore it results in a stable performance of welding operation. In
the case of low input voltage, welding output current increases while arc voltage decreases, as
a consequence, the length of arc, which is not sucient, will automatically compensate and the
modulation of arc force is accessible. In case of the input arc voltage being too low to maintain
arc, the output of this welding equipment descends steeply, which avoids the splash generated
due to over current input.
When TIG welding, this welding equipment features stable output current and that the welding
current output does not change with the variation of the length of arc. In case of short circuit of
electrode, the voltage automatically decreases to 0V, which limits the impairment of electrode
and pollution to environment.
Warranty of maintenance for main components is one years.
During the warranty maintenance period, all maintenance is free of charge, not including any
deliberate damage or alteration to this welding equipment.
In the case of a fault with the inverter machine, only qualied electricians are authorized to carry
out repairs.
