Operation Safety - Kemppi WELDFORCE KWF 200S Operation Instructions Manual

1.3. OPERATION SAFETY

Please study these Operation safety instructions and respect them when installing, operating and
servicing the machine.
Welding arc and spatters
Welding arc hurts unprotected eyes. Use a proper face shield fitted with a correct filter and cover
plates to protect your eyes, face, neck and ears from the sparks and rays of the welding arc when
welding or observing welding. Warn bystanders not to watch the arc and not to expose themselves
to the welding arc rays or to hot metal. Be careful also with reflecting arc flash.
Welding arc and spatter burn unprotected skin. Use safety gloves and protective clothing. Wear
flameproof gauntiet-type gloves, a heavy long-sleeve shirt, cuffles trousers, high-topped shoes,
and welding helmet or cap (for hair protection) to protect the skin from arc rays and hot sparks
or hot metal.
Wear ear plugs or other ear protection devices when welding equipment.
Protect other nearby personnel from arc rays and hot sparks with a suitable non-flammable
partition.
Danger for fire or explosion
Pay attention to fire safety regulations. Remove flammable or explosive materials from welding
place at least 35 feet (11 meters) or protect them with flame-proof covers.
Always ensure that you have sufficient fire fighting equipment available where you are welding
and you have a trained fire watcher ready to use it. Be prepared for hazards in special welding
jobs, eg. for the danger of fire or explosion when welding container type work pieces. Note! Fire
can break out from sparks even several hours after the welding work has been finished!
Combustible materials include but are not limited to wood, clothing, sawdust, gasoline, kerosene,
paints, solvents, natural gases, acetylene, propane, and similar articles.
Compressed gas cylinders are potentially dangerous, refer to the suppliers for proper handling
procedures.
Mains voltage
Do not touch live electrical parts.
Never take welding machine inside a work piece (eg. container or truck). Do not place welding
machine on a wet surface. When welding in a damp area or when standing on metal, make sure you
are well insulated by wearing dry cloves, rubber or soled shoes, and by standing on dry board or
platform. Keep everything dry you might touch, including clothing, wor area, welding gun, torch
and welding machines. Fix water leaks immediately.
Always check cables before operating the machine. Change damaged cables without delay. Damaged
cables may cause an injury or set out a fire. Do not overlay the gables. Connection cable must not
be crushed, it must not touch sharp edges or hot work pieces.
The ground cable should be connected to building as close to the work area as possible. Grounds
connected to building framework or other locations remote to the work area reduce efficiency and
increase the potential hazard of electric shock.
When not welding, turn equipment OFF. Accidental grounding can cause overheating and create
a fire hazard. Do not coil or loop the around parts of the body.
Welding power circuit
Isolate yourself by using proper protective clothing, do not wear wet clothing. Never work on a
wet surface or use defect cables. Do not put the MIG-gun or welding cables on welding machine
or on other electric equipment. Avoid the possibility of the cutting current passing through lifting
chains, crane cables or other electrical paths. Do not press the MIG-gun switch, if the gun is not
directed towards a work piece.
