torch need to make sure under “water-cooling”condition,
otherwise the cutting torch will be damaged.

PREPARE FOR WELDING
5.1
Connect cutting machine
According with 4.5 and F1 requirement 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 than 0.2Mpa,cutting machine will stop
wor, if everything is ok, air pressure light will turn off, please put “air test/ cutting”
switch to “cutting” at this time.
Note:air pressure
≥
0.45
～
0.6MPa
，
flow rate
≥
300L/min.
c. This cutting machine standard collocate adopt non-contact cutting torch. When cutting, nozzel will not
meet work piece due to if they get to each other, it’s easy to damage electrode and nozzel. at this time,
in order to control cutting torch height, we usually match series of cutting tool
、
photoelectric follow-
up
、
robot and CNC cutting machien tool.
Operation point as follows:
a) Trolley the cutting torch to meet workpiece, and keep distance 2-5mm, make sure nozzel axes
apeak to surface of work piece
（

）
.
b) Turn on cutting switch, ignite plasma arc, cutting work piece 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. Pleasse control towing angle in 10°
（

）
,
cutting quality is perfect. If too fast won’t pierce, even spatter.
c) Generally speaking cutting from edge of work piece, when need to cut from middle of work piece,
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 nozzel and work piece an included angle about 75°, then, turn on torch switch,
ignite arc to pierce work piece, adjust torch axes to apeak work piece. 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. If finish cutting, unlock torch switch, break off plasma arc.compressed air will be delayed
spurt to cooling cutting torch. After some minutes pls move torch to finish cutting.
