Tweco FP-260 - Manual (Page 4)

3. NEVER look at the arc without proper protection to the eyes.
4. Thoroughly clean metal of rust or paint to avoid producing harmful fumes. Parts degreased with a solvent
must dry before welding.
5. NEVER weld on metals or coated metals containing zinc, mercury, chromium, graphite, lead, cadmium or
beryllium unless the operator and the people standing in the same area use an air-supplied respirator.
SAFETY INSTRUCTIONS
For your safety, BEFORE connecting the power source to the line, follow these instructions:
1. Insert an adequate two-pole switch, equipped with time-delay fuses, before the main outlet.
2. Make the single-phase connection with a two-pole plug compatible with the above mentioned outlet.
3. The two wires of the two-pole input cable are used for the connection with the single-phase line. The yel-
low/green wire is for the compulsory connection to the ground in the welding area.
4. When working in a confined space, keep the power source outside the welding area and fix the ground cable
to the workpiece. NEVER work in a damp or wet area.
5. DO NOT use damaged input or welding cables.
6. NEVER operate the power source without its panels in place. This could cause serious injury to the operator
and could damage the equipment.
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 fire-
proof covers.
NEVER perform welding operations on a container that has held toxic, com-
bustible or flammable liquids or vapors. NEVER perform welding operations in an area con-
taining combustible vapors, flammable liquids or explosive dust.
VENTILATION
Ventilate welding work areas adequately. Maintain sufficient air flow to prevent
accumulation of explosive or toxic concentrations of gases. Welding operations using cer-
tain combinations of metals, coatings and gases generate toxic fumes. Use respiratory
protection equipment in these circumstances. 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 supply 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.
