PREPARE FOR CUTTING
5.1 Connect cutting machine
According with 4.5and FIG1
、
FIG 2
、
FIG 3 to connect with cutting machine
5.2 Cutting operation
a. Turn on the power source ,cooling fan will be work as usual.
b. Turn on gas switch and put the switch to “air test”,then rotate air pressure regulator to chose
suitable gas flow rate.If air pressure low than0.2Mpa ,cutting machine will stop work,if
everything is ok, air pressure light will turn off,please put “air test/cutting “switch to
“cutting”at the same time.
Note
：
air pressure≥0.45
～
0.6MPa
，
flow rate ≥300L/min
。
c. This cutting machine standard collocation adopt non-contact cutting torch.When cutting
machine ,nozzle will not meet workpiece due to if they get to each other, it’s easy to damage
electrode and nozzle. At this time,in order to control cutting torch height, we usually match
series of cutting tool
、
photoelectric follow up
、
robot and CNC cutting machine tool.
Operation points as following
：
a) Trolly the cutting torch to meet workpiece,and keep distance 2-5mm,make sure nozzle
axes apeak to surface of workpiece and don’t touch.( FIG6)
b) Turn on cutting switch ,ignite plasma arc ,cutting workpiece fully ,keep an even speed to
move along with cutting direction,Cutting speed is :base on cutting pierce,be fit for rapid
to cut ,if too slow will affect cutting quality even arc break off. Please control towing
angle in 10°(F6), cutting quality is perfect,if too fast won’t pierce,even spatter.
c) Generally speaking cutting from the edge of workpiece,when need to cut from the middle
of workpiece,if material thickness is≤5mm(stainless steel or carton steel,if other
material,need to cut back on cutting thickness),can directly cutting pierce.Method:put
cutting torch on starting point of cutting sew,make nozzle and workpiece an included
angle about 75°,then turn on torch switch,ignite arc to pierce workpiece,adjust torch axes
to apeak workpiece.But if material thickness≥5mm and need to cut in middle,please drill a
hole which diameter is ≥3mm,ignite arc to cut in hole.
d) If finish cutting ,unlock torch switch,break off plasma arc.compress air will be delayed
spurt to cooling cutting torch.After some minutes please move torch to finish cutting.
