1. MACHINE DESCRIPTION:

The welding machine is a rectifier adopting the most advanced inverter technology.
The development of inverter arc welding equipment benefits from the development of the inverter power
supply theory and components. Inverter arc welding power source utilizes high-power component IGBT to
transfer 50/60Hz frequency up to high frequency (such as 50KHz), then reduces the voltage and commutates,
and outputs high-power voltage via PWM technology. Because of the great reduce of the main transformer's
weight and volume; the efficiency increases by 30%.
The welding power source can offer stronger, more concentrated and more stable arc. When electrode and
workpiece get short circuit, its response will be quicker. That means it is easier to design into welding machine
with different dynamic characteristics, and it even can be adjusted for specialty to make arc softer or harder.
MMA welding machine (series SBC) has the following characteristics: a circuit structure using board design,
simple circuit and easy to maintain. The main circuit uses half-bridge inverter (single tube IGBT), ferrite core
transformer, high power fast recovery diodes technology. The machine has over-current, overheating,
under-voltage automatic protection function. This welding machine with automatic thrust, hot arc function, and
stable output current, thus its performance is reliable. This series welding machine can use acidic, alkaline
electrode Φ 4.0 and below. It can be used in metal processing, maintenance, home use, high altitude,
fieldwork, indoor and outdoor decoration, etc. When compared with similar products at home and abroad, it
characterizes with its simple and easy structure, small volume, light weight (mini), reliable performance, high
efficiency and energy saving, convenient installation and easy operation etc.
The characteristic of arc welding machine (series C) is: Wide grid adaptability, strong adaptability for the
grid voltage. When applying our mature three horizontal single duct structure, at the same time the radiator
segmentation technology is well adopted to the full insulation and protection of electronic components. The
main loop of the power supply adopts full bridge inverter topology structure, nanometer magnetic core
transformer, high power rectifier module, EMC, thus make the circuit easy to maintain. Current-mode PWM
control scheme (C platform technology) monitors output current by each pulse, thus greatly improve
machine's reliability and stability. It has a good dynamic characteristic, easy arc-starting, stable arc, the strong
arc stiffness, and easy-control welding pool. It also characterizes for its under voltage, over current,
overheating protection function, which make it safe and reliable. The simple and easy digital display interface
make the operation and maintenance more convenient. Some models can provide carbon arc air gouging.
This series of models with enough high no-load voltage and output ability, very well suitable for long-term
welding. Make it possible to be used for railways, highways, construction sites, such as electric power
construction, petroleum, chemical industry construction, pipe installation, steel structure manufacture
installation, outdoor generator operation, etc. When compared with similar products at home and abroad, it
characterizes for its simple and easy structure, small volume, light weight, reliable performance, high
efficiency and energy saving, convenient installation, easy operation, etc.
