covering open skin.
• After operating do not touch the welding seam and
an area around it - you can be badly burnt�
• After operating the electrode end is of high tempera-
ture thus the replacement of the electrode has to be
done only in protective gloves and the electrode waste
must be put into a metal box�
• Observe rules and wear special protective clothes:
everything should be fully buttoned; valves of pockets
are to be let out; do not tuck a jacket in breeches, and
wear breeches atop a footwear�
• When welding steel and nonferrous metals, vari-
ous chemical compounds (oxygen with zinc, cooper,
tin, etc.) are formed which negatively influence on the
worker health� Use individual protective means and
provide good ventilation of a workplace�
• Beware of ignition of surrounding objects due to
high temperature of a welding arch, or particles of the
melt metal� Remember, invisible design components
(wooden beams, insulation materials, etc�) can catch
fire as well.
• Do not work next to highly inflammable liquids, gas-
es and items (timber, paper, etc�)�
• When performing works over the machine, make
sure that red-hot objects or metal chips do not fall on it
and welding cables�
• Be cautious when executing welding works on ca-
pacities or pipelines in which combustible or toxic
substances were stored� Perform their decontamina-
tion before the beginning of work; evaporations of sub-
stances inside capacities or pipelines can cause explo-
sion, explosion or poisoning�
• Never execute welding works on the capacities
which are under pressure�
• Do not use the machine for defrosting frozen pipes�
• When working heights, observe safety procedure for
working heights�
After finishing operations
• After the final shut-off, examine a place where weld-
ing works were carried out, do not leave decaying sub-
jects, or the heated particles of metal - they can cause
a fire.
• After finishing operation do not switch off the ma-
chine at once, wait several minutes for the machine to
cool down sufficiently.
