Noise; Electromagnetic Compatibility; Protective Welding Gases - Helvi Maxitech 360C Manuel D'instructions

NOISE

Noise can cause permanent hearing loss.
Welding processes can cause noise levels that
exceed safe limits. You must protect your ears
from loud noise to prevent permanent loss of
hearing.
• To protect your hearing from loud noise, wear
protective ear plugs and/or ear muffs.
• Noise levels should be measured to be sure
the decibels (sound) do not exceed safe levels.

ELECTROMAGNETIC COMPATIBILITY

Before installing your welder, carry out an inspection
of the surrounding area, observing the following
guidelines:
• Make sure that there are no other power sup-
ply cables, control lines, telephone leads or
other equipment near the unit.
• Make sure that there are no radio receivers,
television appliances, computers or other
control systems near the unit.
• People with pace-maker or hearing-prosthe-
sis should keep far from the power source.
! In particular cases special protection
measures may be required.
Interference can be reduced by following these sug-
gestions:
• If there is interference in the power source
line, an E.M.T. filter can be mounted between
the power supply and the power source;
• The output cables of the power source should
be not too uch long, kept together and con-
nected to ground;
• After the maintenance all the panels of the po-
wer source must be securely fastened in place.

PROTECTIVE WELDING GASES

Shielding gas cylinders contain gas under
high pressure. If damaged, a cylinder can
explode. Treat them carefully.
• These welders use only inert or non-flamma-
ble gases for welding arc protection. It is im-
portant to choose the appropriate gas for the
type of welding being performed;
• Do not use gas from unidentified cylinders or
damaged cylinders;
• Do not connnect the cylinder directly to the
welder, use a pressure regulator;
• Make sure the pressure regulator and the
gauges function properly;
• Do not lubricate the regulator with oil or gre-
ase;
• Each regulator is designed for use with a spe-
cific gas. Make sure the regulator is designed
for the protective gas being used;
• Make sure that the cylinder is safely secured
tightly to the welder with the chain provided.
• Never expose cylinders to excessive heat,
sparks, slag or flame;
• Make sure that the gas hose is in good condi-
tion;
• Keep the gas hose away from the working area.
