Safety Precautions - Kemper Mini-Weldmaster Manual Del Usuario

A. Application
The KEMPER Mini-Weldmaster is primarily used for source extraction of welding smoke.
The contaminated air is removed from the breathing zone of the welder. The extracted
harmful substances (particles) are trapped by the filter insert. The cleaned air is then
reurned to the room. The result is a better an healthier work environment.
B. Function
The contaminated air is removed from the breathing zone of the welder by exhaust nozzles
which are placed with magnets in an angle above the item to be welded. The contaminated
air flows through the flexible hoses and into the Mini-Weldmaster. There the impurities are
mechanically filtered out.
Filtering is accomplished in three stages:
1. The pre-filter removes coarse particles
2. The particulate filter removes even the smallest particles, down to under 0,1 micron
in diameter (efficiency greater than 99,997 % DOP-Test)
3. The Mini-Weldmaster is also available with an activated charcoal filter (optional).
This filter is inserted underneath the unit´s main filter (HEPA filter).
It is used to adsorb the hazardous gases and odors from the air stream.
The cleaned air is extracted by two turbines and then returned to the work place
through an exhaust grid. It can be returned usually to the workplace.
This is not allowed in case of welding smoke with a share of carcinogenic particles,
c. g. when welding highgrade steel (see TRGS 560).
However, in spite of the high efficiency, if you do not want to return the cleaned air
to the workplace, it can be exhausted outside using an adapter and the respective hose.
C. Safety Precautions
Caution:
When using electrical devices, the following basic safety measures must be followed
to prevent shock, inury or fire.
Read and follow these instruction before using the filter unit.
• Keep this Installation and Operating Manual handy
• Do not use the unit to extract easily flammable or explosive gases
• Do not use the unit to extract crrosive substances
• Do not expose the connecting cable to heat, oil or sharp edges
• Make sure the unit stands stable and secure
• Use only original equipment filters
• Do not operate the unit without filter inserts
• Contaminants in the extracted air will destroy the blower!
• Always unplug unit before opening it
• Never cover intake or exhaust openings
• Protect the unit from dampness
• Do not extract vapors containing water (steam).
