pleted your work, always check that the area
is free of glowing or smoldering material.
2.5 SHIELDING GAS
Use the correct shielding gas for the welding
process. Be sure that the regulator/ fl owmeter
mounted on the cylinder is working well.
Remember to keep away the cylinder from
any source of heat.
2.6 PERMITTED NOISE LEVELS 86/188/
EEC RULE.
Under normal circumstances the equipment
used for electric arc welding does not exce-
ed the permitted 80 dBA. However in cer-
tain conditions eg. high welding parameters
in con fi ned spaces, noise levels may exce-
ed the permitted level. For this reason it is
strongly recommended that operatives wear
appropriate ear protection.
2.7 ELECTROMAGNETIC
COMPATIBILITY.
Before installing the STICK/TIG welding unit,
carry out an inspection of the surrounding
area, observing the following guidelines:
1- Make sure that there are no other power
supply cables, control lines, telephone leads
or other equipment near the unit.
2- Make sure that there are no radio recei-
vers or television appliances.
3- Make sure there are no computers or other
control systems.
4- Make sure that there is no-one with a pa-
cemaker or hearing aid in the area around
the unit.
5- Check the immunity of any other equipment
operating in the same environment.
In certain cases additional protective measu-
res may be required.
Interference can be reduced in the following
ways:
1- If there is interference in the power sup-
ply line, an E.M.C. fi lter should be inserted
between the mains and the unit.
2- The output cables of the unit should be
shortened; these should be kept close toge-
ther and stretched along the ground.
3- All the panels of the unit should be correct-
ly closed after carrying out maintenance.
2.8 Medical and fi rst aid treatment
First aid facilities and a quali fi ed fi rst aid per-
son should be available for each shift for im-
mediate treatment of electrical shock victims.
A medical facility should be close by for im-
mediate treatment of fl ash burns of the eye
and skin burns.
EMERGENCY FIRST AID:
Call physician and ambulance immedia-
tely.
Use First Aid techniques recommended
by The Red Cross.
DANGER: ELECTRIC SHOCK CAN BE
FATAL
If person is unconscious and electric
shock is suspected , do not touch the
person if he or she is in contact with wel-
ding equipment, or other live electrical
parts. Disconnect (open) power at wall
switch and then use First Aid. Dry wood,
wooden broom, or other insulating mate-
rial can be used to move
cables, if necessary, away from the per-
son.
