Fire Prevention
Welding operations use fire or combustion as a
basic tool.
1. The work area MUST have a fireproof
floor.
2. Work benches or tables used during
welding operations MUST have fireproof
tops. DO NOT weld on wooden work
benches.
3. Use heat-resistant shields or other
approved material to protect nearby walls
or unprotected flooring from sparks and
hot metal.
4. Keep an approved fire extinguisher of the
proper size and type in the work area.
Inspect it regularly to ensure that it is in
proper working order. Know how to use
the fire extinguisher.
5. Remove all combustible materials from
the work site. If you can not remove
them, protect them with fireproof covers.
ƽWARNING NEVER perform welding
operations on a container that has held toxic,
combustible or flammable liquids or vapors.
NEVER perform welding operations in an
area containing combustible vapors, flamma-
ble liquids or explosive dust.
Ventilation
ƽWARNING Ventilate welding work areas
adequately. Maintain sufficient air flow to
prevent accumulation of explosive or toxic
concentrations of gases. Welding operations
using certain combinations of metals, coat-
ings and gases generate toxic fumes. Use
respiratory protection equipment in these cir-
cumstances. BEFORE welding, read and
understand the Material Safety Data Sheet
for the welding alloy.
Electromagnetic Compatibility
BEFORE installing a MIG power source,
inspect the surrounding area checking the
following points:
1. Make sure there are no other power sup-
ply cables, control lines, telephone cables
or other devices close to the power
source.
2. Make sure that telephones, televisions,
computers or other control systems are
not in the working area.
3. People with pace-makers or hearing aides
should keep far from the power source.
In particular cases, special protection
measures may be required.
Reduce interference by following these sug-
gestions:
1. If there is interference in the power
source line, mount an E.M.T. filter
between the power supply and the
power source.
2. Shorten the output cables of the power
source, keep them together and connect-
ed to ground.
3. Securely fasten the panels of the power
source in place after performing mainte-
nance.
