1, No remote cable design, reduce the disconnection fault, improve mobility.
2, Wire diameter selection, solid core / flux core wire switching and arc selection function.
3, Unified / individual adjustment conversion function.
4, Easy to operate, easy to maintain.
5, Unique anti-main burning damage patent technology and multiple protection functions.
6, The structure design is tight, high reliability, adapt to harsh environment.
7, The standard machine is equipped with automatic welding analog interface.
●Non-remote control cable design
By carrying the remote controller on the wire feeder and improvement of control circuit,the original two
pieces of cable was integrated to one piece.This realized light weight,improved mobility and decreased
wire breaking trouble.
●Convincing high reliability
●High insulation strength(Class H),high temperature resistance and good dust proof structure are adopted
in main transformer and reactor.
●IP(International Protection) class of enelosure is IP21S and it effectively prevents the affection and interference of the main circuit to the control circuit.And moisture-proof,dripproof and dust-proof structure enables the operation under adverse circumstances.
The special patented technology preventing the damage of main transformer further improves the safety
performance and reliability of the machine.
●Good welding performance
●KR2 adopts the special control circuit which realizes low spatter welding in short circuit transfer and spray
transfer of CO2/MAG welding.
●The arc starting circuit ensures high rate of success of arc srart,which reaches to almost 100% under any
operating mode within the technical specifications. It is also possible to be equipped with various automatic
welding systems.
●Various kinds of protection functions,convenient functions and good
expandability.
●Overheat protection
●Under-voltage protection
●Output over-current protection
●Lighting-proof circuit
●Adjustable burn-back time
●Pre-flow on-off selection
●Current detection terminal for peripheral equipment
●Individual and Simple Unitary mode
