good )
。
2
、
electric nozzle , sprayer, wire-fed soft tube are consume goods, should beoften
replaced ， please use such parts provided by our company.

quality of wire can effect welding quality directly , bad quality wire
，
surface not
clean, coated easy drop
，
easy block soft tube , short the tube life, so, use good brand
wire-fed machine and wire.
4
、 if wire-fed roller and press roller contact good or not ,it will effect wire feed
stability .Wire-fed roller and press roller should be clean on contact , can not be

Ф 1.0
、
Ф 1.2 wire ; KR500 welding
machine use Ф 1.2 、 Ф 1.4 、 Ф 1.6 wire .

soft tube will go
out of torch head ,thus cut off unwanted piece .But attention :a .wire-fed soft tube is
not too
long,otherwise nozzle will be difficult to screw in ,or let soft tube bend too
much ,badly effect
wire feed ability .it's better to screw nozzle about 3-5mm to soft tube head .b.check if
wire-fed soft
tube cut smooth ,if turn up or inner bend ,must be taken out again
，
grinding orderly
，
around should be a little angle.finally ,install gas distributary part ,nozzle ,nozzle
base ,sprayer ,and finish at all .
