CONNECTABLE PLASMA CUTTER 40A
EXPLOSIONS
• Do not cut above or near containers under pressure.
• Do not cut in environments containing explosive 4 dusts, gases or vapours.
• This plasma cutter uses compressed air to work; should you use compressed air
bottles follow suitable precautions:
A) CYLINDERS
• Do not directly connect cylinders to reducing unit without a pressure regulator; pressure might
exceed the reducing unit capacity making it explode.
• Feeding pressure must not exceed 0.8MPa
• Handle or use pressure cylinders in conformity with the existing rules. Do not use leaking or
damaged cylinders.
• Do not use cylinders which are not properly secured.
• Do not carry cylinders whose content is not clearly identified. Never lubricate cylinder valves
with oil or grease.
• Do not put electrically in contact cylinder with plasma arc.
• Do not expose cylinders to excessive heat, sparks, hot metal or flames. Do not tamper with
cylinder valves.
• Do not try to losen all tight valves by means of hammers, keys or something else.
B) PRESSURE REGULATORS
• Keep pressure regulators in good conditions. Damaged regulators may give rise to damage or
accidents; they should only be repaired by skilled personnel.
• Do not use regulators for gases other than those they are manufactured for. Never use a leaking
or damaged regulator.
• Never lubricate regulators with oil or grease.
C) AIR HOSES
• Replace air hoses if damaged.
• Keep hoses unwound so as to avoid bending.
• Keep excess hose wound and keep it out of the working area to avoid any damage.
BURNS
• Wear fire-proof clothes all over your body to protect your skin against burns caused by ultraviolet
radiations from the arc, from sparks and hot metal.
• Wear no turn-up trousers to prevent sparks and metal to deposit in them.
• Wait for the torch to be cooled down and then switch the unit off before touching the front side
of the torch.
• Torch is provided with a pilot arc, then as soon as you press the button, the plasma spark starts
even if earth cable is not connected. Avoid directing jet towards your own body or towards
other people surrounding the cutting area.
• To prevent spark to starts by chance, always switch the unit off before putting down your
torch.
• Do not carry combustible material, such as lighters or matches in pocket.
