For MIG/MAG and flux-cored welding, the corresponding process, wire thickness, and welding voltage are set, and the corresponding wire feed speed is stored as a corresponding setting via a defined synergy curve.

The VRD (Voltage Reduction Device) is used to reduce the output voltage to a safe level when the welding machine is switched on but not ready to weld. This ensures the safety of the operator, who can safely come into contact with the electrode as long as welding operations have not resumed.

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 mm2. Use of extension cables of dierent 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 wit

hout 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 at 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 re or explosion. Never use the appliance in a ammable environment. Wood, sawdust, „varnishes“, petrol, kerosine, natural gas, acetylene, propane and similar ammable mate

rials must be removed from the place of work and the surrounding area or protected against sparks ying away. To extinguish re, a suitable re 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 re

actions. 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 sucient air inlet and outlet. A leaking gas bottle may reduce the share of oxygen in the inhaled air and therefore represent a risk of suocation. Before use, make sure the gas bottle contains gas designed for the work being done. Gas bottles must always be safely xed in a vertical position on a wall support or on a specially manufac

tured gas bottle cart. The bottle with shielding gas and the xed adjust

ment gas current equipment must not be moved. The gas bottle valve must be closed during transport. Close the gas bottle valve after use.

g) the resistance of other equipment in the vicinity to interference. The user must ensure that other equipment used in the environment is suitable for such a purpose. This may require additional protective measures; h) the time of day during which the welding, cut

ting, or other activities must be carried out. The extent of that surrounding area that must be considered depends on how the building is constructed, and the other activities taking place there. This area may extend beyond the limits of the premises Evaluation of the welding machine / cutting equipment In addition to the assessment of the area, the arc welding machines/cutting equipment can be evaluated to assess and resolve cases of interference. An assessment of electromagnetic interference should include in situ measure

ments, as specied in section 10 of CISPR 11:2009. In-situ measurements can also be made to gauge the eectiveness of any minimi- sation measures implemented. Guidance for minimisation measures: Public power supplies Welders machines/cutting equipment should be connected to the public power supply as per the manufacturer’s recommendations. If there is any interference, it may be necessary to take additional precautions, such as tting lters for the mains connection. Consider shielding the mains cable of permanently installed welding machines/cutting equipment with a metal pipe or similar. The shielding should be electrically connected for its entire length. The shielding should be connected to the welding machine/ cutting equipment power source to achieve good electrical contact between the sheath and the housing of the welding machine/cutter power source. Instructions for the installation and opera- tion of an arc welding device to prevent possible electromagnetic interference: As the manufacturer, we recommend that the following assessments and measures be carried out by a qualied electrician. General The user is responsible for setting up and operating the arc welding machines/cutting equipment in accordance with the manufactur- er’s instructions. If electromagnetic interference is detected, it is the responsibility of the user of the arc welding machines/cutting equipment to nd a solution with the technical assistance of the manufacturer. In some cases, the measure needed may simply consist of earthing the welding circuit (see note). In other cases, it may include complete electromagnetic shielding of the power source of the arc welding machine/ cutting equipment and the workpiece, com- bined with input lters. In all cases, electromag- netic interference must be reduced until it no longer causes any disturbance. Note The approach taken to earthing the welding circuit depends on the local safety regulations. Changing the earthing to improve electromag

netic compatibility may increase the risk of accidents or damage to equipment Assessing the surroundings Before setting up the arc welding machines and/or cutting equipment, the user must assess possible electromagnetic problems in the sur- roundings. When doing so, the following factors must be taken into account: a) other mains cables, control cables, signal and telecommunication cables above, below and next to the arc welding machines and/or cutting equipment; b) Audio and television broadcast transmitters and receivers; c) Computers and other control devices; d) Safety equipment, e.g. protection for com

mercial facilities; e) the health of persons nearby, e.g. those using pacemakers and hearing aids; f) Calibration and measurement equipment; ENGLISH33

Maintenance of the arc welding machines/ cutting equipment Arc welding machines/cutting equipment should be regularly maintained as per the manufacturer’s recommendations. All access and service doors and covers should be closed and well secured when the welding machine/ cutting equipment is in operation. With the exception of the changes and adjustments specied in the manufacturer’s instructions, the welding machines/cutting equipment should not be modied in any way. In particular, the spark gaps of arc ignition and stabilisation devices should be adjusted and maintained in accordance with the manufacturer’s recommendations. Welding cables Welding cables should be as short as possible, close together, and should run across or near the ground. Electrical bonding The electrical interconnection of all metallic parts in and next to a welding machine/cutting equipment should be taken into consideration. Metallic parts connected to the workpiece can increase the risk of the welder receiving an elec- tric shock from touching these metallic parts and the electrode at the same time. The welder should be electrically insulated from all of these connected metal parts. Earthing the workpiece It may be that the workpiece is not already connected to earth for reasons of electrical safety or because of its size and location, e.g. a ship’s hull or steel structures. If so, grounding the workpiece can reduce emissions in some, but not all, cases. Ensure that earthing the workpiece does not increase the risk of accident for the user or cause the destruction of other electrical equipment. If necessary, the work- piece must be grounded by a direct connection to the workpiece. In countries where a direct connection is prohibited, the connection should be achieved using suitable capacitors, selected in accordance with national regulations. Screening Selective screening of other cables and equip- ment in the vicinity can reduce irradiation. The screening of the entire welding/cutting set-up may be considered for special applications.

Class A (IEC 60974-10): If you intend to use the apparatus in residential sur- roundings supplied by the low voltage mains supply, an electromagnetic lter may be required to suppress electrical disturbance to a level where they will no longer be a nuisance to the user. The apparatus may be used in industrial or other areas where power is not supplied by municipal LV mains. Class A apparatus are not intended for use in residen

tial areas where power is supplied via municipal LV mains, since unfavourable power conditions may cau- se interference. As a user, you must make sure, after consultation with your energy provider, if necessary, that your point of connection on which the machine is to be operated meets the requirements above. The user is responsible for faults arising from the welding. Symbols Caution! Read the Operating Instruc- tions! Wear personal protective equipment. Welding mask to be used!
