BX3
Series AC Arc Welding Machine
|
|
Welding-machines of series BX3 which using move-coil structure can
manually weld moderate and low-alloy steel part, it also can be used
in electric arc cutting. With such properties as electric current's
constant adjusting，stable and reliable performance and low failure
rate, it applies to mining industry and enterprise production . |
 |
First.
Use
BX3
series moving circle AC
arc
welding machines
for single hand. 3-30mm thick in the welding of low carbon steel and low alloy
steel, and a variety of mechanical structures, use
1.5-6 mm rod, in the whole scope of the current regulation can keep
stable welding arc welding spatter small, Weld smoothing. The structure may be
filled work also.

A
continuous load current rate of welding and welding cycle than access time.
=t/T*100% loading rate is sustained, "t" for the welding current
access time "T" for the entire period (the sum of working hours and
rest periods) cycle 5 minutes.
Third.
The adjustment of welding current
Welding current regulator for the two tranches, Ⅰ, Ⅱ followed by the
combination of two tranches for a complete switch. Fine adjustment of welding
current rotation on the handle conditioning coil position, and change the size
to achieve leakage reactance.
Fourth.
The attention
1、Pre-operational
check carefully whether the nut tightening wiring, grounding grounding line
reliability.
2、The
welding process, seeking Combined Switch shift, we must stop welding, the
welding process must not shift!
3、The
use of welding, the welding machine welding current than allowed welding value.
4、Welder
not by rain, snow-drenched, should be placed on a dry place.
