PT-600 Mechanized Plasma Cutting Torch

SECTION 1
!
DANGER
Hydrogen explosion hazard.
SAFETY
• Do not cut under water with Hydrogen gas!
• Hydrogen explosions can cause personal
injury or death.
• Hydrogen can create explosive gas pockets
in the water table. These pockets will
explode when ignited by sparks or the
plasma arc.
• Before cutting, be aware of possible
hydrogen sources in the water table –
molten metal reaction, slow chemical
reaction and some plasma gases.
• Explosive gas pockets accumulate
underneath the cutting plate and inside the
water table.
• Clean slag (especially fine particles) from
bottom of table frequently. Refill table with
clean water.
• Do not leave plate on table overnight.
• If water table has not been used for several
hours, vibrate or jolt it to break up hydrogen
pockets before laying plate on the table.
• If possible, change water level between cuts
to break up hydrogen pockets.
• Maintain water pH level near 7 (neutral).
• Programmed part spacing should be a
minimum of twice the kerf width to ensure
material is always under the kerf.
1.6 Service Precautions
CAUTION
• When cutting above water, use fans to
circulate air between plate and water
surface.
Establish and adhere to preventive maintenance. A
composite program can be established from
recommended schedules in the instruction literature.
Avoid leaving test equipment or hand tools on
machine. Severe electrical or mechanical damage
could occur to equipment or machine.
