In case of any doubts about connection and operation refer please to our customer center
Specified Conditions Of Use
Welder in protective atmosphere for thermal connection of ferrous metals by melting edges and including mixture
Do not use this product in any other way as stated for normal use. Not observing general regulations in force and instructions from this manual does not make the manufacturer liable for damages.
Safety instructions
WARNING! Electric shock! There is a risk of an injury caused by electric shock!
Operation is only allowed with a safety switch against stray current (RCD max. stray current of 30mA).
IP21 protection degree of the welder. The welder must not be exposed to rain and moisture when being operated or stored.
Check the voltage. Technical data given on the type label must correspond with electric network voltage.
Insert the plug of the electrical cable in a socket of suitable shape, voltage and frequency complying with current regulations.
Use extension cables with a maximum length of 5 meters and with a cable cross-section of not less than 1.5 mm ^2 . Use of extension cables of different length and cross-section and also of adapters and multiple sockets should be avoided.
Check the cable and/or socket for damages before the appliance putting into operation.
Defective cable or plug may cause electric shock.
Do not pull the service cable to pull the plug out of socket.
Do not expose yourself or other persons without protection to electric arc or hot metal. Spraying welding pearls may cause burns.
A suitable welding shield, protective clothes and protective gloves to be worn at all times.
Long-term inhalation of welding gases may be harmful to your health.
Work with an exhaust system or in well ventilated spaces. Avoid direct inhalation of gases.
Contact with the hose bundle nozzle and the material being processed may cause burns. Special welding gloves to be worn at all times.
Let the hose bundle nozzle and the material being processed cool down after being operated.
Long-term working with the appliance may damage hearing. Hearing protection to be used at all times.
Welder may only be used on a flat surface and with a properly secured gas bottle.
Make sure the welding smoke is exhausted or the place of welding ventilated well.
Hot slag and sparks may cause fire or explosion. Never use the appliance in a flammable environment.
Wood, sawdust, "varnishes", petrol, kerosine, natural gas, acetylene, propane and similar flammable materials must be removed from the place of work and the surrounding area or protected against sparks flying away.
To extinguish fire, a suitable fire extinguisher must be made ready nearby.
No welding or cutting on closed vessels and pipes.
No welding or cutting on vessels and pipes if they are open, containing materials able to explode due to heat or moisture or able to cause other dangerous reactions.
Never use the welder to defrost frozen pipes.
The gas bottle must necessarily be secured against falling. The welder must never be lifted together with the gas bottle. Special regulations apply to the transport of gas bottles.
Handling of gas bottles.
Make sure the gas bottles are used and stored in rooms with sufficient air inlet and outlet.
A leaking gas bottle may reduce the share of oxygen in the inhaled air and therefore represent a risk of suffocation.
Before use, make sure the gas bottle contains gas designed for the work being done.
Gas bottles must always be safely fixed in a vertical position on a wall support or on a specially manufactured gas bottle cart.
The bottle with shielding gas and the fixed adjustment gas current equipment must not be moved. The gas bottle valve must be closed during transport.
Close the gas bottle valve after use.
