Page 8: Product Description
PRODUCT DESCRIPTION The welding machine applies the most advanced inversion technology in the world. The principle of inversion is to transform the power frequency of 50Hz/60Hz into direct current and invert it into high frequency through high-power device IGBT, then perform voltage-drop and commutation with the output high-power D.C power supply via Pulse Width Modulation (PWM). -

Page 10: Installation Instruction
INSTALLATION INSTRUCTION The welding equipment is equipped with power voltage compensation device. It keeps the machine work normally when power voltage fluctuating ±15% of rated voltage. When using long cable, in order to reduce voltage drop, big section cable is suggested. If the cable is too long, it will affect the performance of arcing and other system function, it is suggested to use the recommend length. - Page 11 Explanatory drawing for Installation of 300GN: MIG/NBC Power supply Three phase~AC400V meter Gas cylinder Earth clamp Workpiece Welding gun Notes: Turn the welding machine to MMA mode for heating the gas cylinder to prevent CO meter icing when the machine is not working under MIG mode.
