• Read and follow the instructions of the compressed air
cylinders, the associated equipment and the Compressed
Gas Air (CGA) P-1, along with the local regulations.
Danger of FIRE OR EXPLOSION
• Do not place the unit on, above or near combustible
surfaces.
• Do not install the unit near inflammable objects
• Do not overcharge your building wires – make sure your
power supply is appropriate in height and capacity, plus
protected in order to meet this unit necessities.
A FALLING EQUIPMENT may cause injuries
• In heavy units only use the appropriate way to lift them,
never doing it from the chassis, gas cylinders or any other
accessories.
• Use an adequate capacity equipment to lift the unit.
• If you use a forklift to move the unit, make sure its corners
are long enough to extend beyond the opposite side of the
unit.
OVERUSE can cause equipment overheating
• Allow a cooling period. Continue the nominal work cycle. If
the thermal protection appears, patiently change to another
more powerful unit.
• Reduce the current or working cycle before welding again.
• Do not block or filter the unit air flow.
FLYING SPARKLES can cause injuries
• Use a safeguard for the face and eyes protection
• Give form to a tungsten electrode in a grinder only with
the appropriate safeguards in a safe ubication. Use the
necessary protection for your face, hands and body. Do not
breathe the filings.
• Sparkles can cause fire – keep the inflammables
away.
WELDING WIRE can cause injuries
• Do not press the trigger of the torch until it is required.
• Do not point at any part of your body with the torch tip, nor
at any other person or metal object while the wire is going
through it.
MOVING PARTS can cause injuries
• Stay away from every moving part, as fans.
• Keep all the doors, panels, covers or safety guards kept in
their places.
• Let only qualified people remove the doors, panels, covers
or safeguards, and give them as much maintenance as
necessary.
• Reinstall doors, covers or safeguards once the maintenance
is over and always before the input power reconnection.
HIGH FREQUENCY
interference
• High-frequency (H.F.) radiation may interfere with the radio
navigation, safety services, computers and communication
equipment.
• Make sure only qualified people, familiarized with electronic
equipment, install the equipment.
• The user is responsible for having a qualified electrician
near, able to quickly correct any kind of problem caused by
the installation.
• Make sure the installation receives a regular check and
maintenance.
• Keep the high-frequency source panels and doors
completely closed. Keep the distance from the sparkles
on the platins on their correct fixing. Make sure you make
earth connection and protect it against current.
RADIATION can cause
-
ARC WELDING may cause interference
• The electromagnetic energy can interfere with sensitive
electronic equipment like computers or computer-impulse
equipment, as industrial robots.
• Make sure all the equipment in the welding arc is
electromagnetically compatible.
• In order to reduce the possible interferences, keep the
welding cables as short and near as possible, or directly on
the ground, if viable.
• Operate your welding at, at least, 100m away from any
kind of electronically sensitive equipment.
• Make sure the welding unit is installed and earth-connected
according to this manual.
• If the interference still occurs, the operator must use extra
measurements as moving the welding equipment, using
armoured cables and line filters or shielding the working
area.
REDUCING ELECTROMAGNETIC
FIELDS
To reduce the electromagnetic fields (EMF) in the working
area, follow the next procedures:
1. Keep the cables as close as possible, twisting or wrapping
them with sticky tape. You can also use a cable cover.
2. Place the cables aside, far from the operator.
3. Do not hang or wrap the cables on your body.
4. Keep the welding power sources and cables as far as
practical.
5. Plug the clamp (earth clamp) to the piece you are working
with as close to the welding as possible.
In locations with an increased risk of shock and fire, as in
closeness to inflammable products, explosives, height,
restricted freedom of movement, physical contact with
conductive parts, warm and humid environments that reduce
the electric resistance of the human skin and equipment, you
should pay attention to the occupational risks preventions
and the national and international dispositions that may
correspond.
3_COMMISSIONING INSTRUCTIONS
COLOCATION
The unit must be placed in a safe, dry and flat location.
ASSEMBLY
MODELS WITH INNER WINDER
Are completely assembled.
MODELS WITH EXTERNAL WINDER
The power, water and logic connections to the unit are made
through the bond hose. Simply connect the positive cable,
logic connector and water circuit (MIG500BT) sited in the
main machines along the corresponding winder connectors.
The negative connection will be independently made from
the hose.
The MIG500BT model comes with an installed water-cooling
unit for the water-cooled torch. Fill with water the frontal
deposit and prime, if necessary, the circuit.
