Caution!This equipment corresponds to Class A of Electromagnetic compatibility and it is notintended for use in residential locations where the electrical power is provided by thepublic low-voltage supply system. There may be potential difficulties in ensuringelectromagnetic compatibility in those locations, due to conducted as well as radiateddisturbances.
When this equipment should be used in residential locations, then special measuresshould be made to achieve compliance , includingassessment of area and reducing of emission.
Before installing arc welding equipment the user shall make an assessment of potentialelectromagnetic problems in the surrounding area. The following shall be taken intoaccount: a) other supply cables, control cables, signalling and telephone cables, above,below and adjacent to the arc welding equipment; b) radio and television transmittersand receivers; c) computer and other control equipment; d) safety critical equipment, forexample guarding of industrial equipment; e) the health of the people around, forexample the use of pacemakers and hearing aids; f) equipment used for calibration ormeasurement; g) the immunity of other equipment in the environment. The user shallensure that other equipment being used in the environment is compatible. This mayrequire additional protection measures; h) the time of day that welding or other activitiesare to be carried out.
The size of the surrounding area to be considered will depend on the structure of thebuilding and other activities that are taking place. The surrounding area may extendbeyond the boundaries of the premises.
Arc welding equipment should be connected to the public supply system according tothe manufacturer’s recommendations. If interference occurs, it may be necessary to takeadditional precautions such as filtering of the public supply system. Considerationshould be given to shielding the supply cable of permanently installed arc weldingequipment, in metallic conduit or equivalent. Shielding should be electrically continuousthroughout its length. The shielding should be connected to the welding power source sothat good electrical contact is maintained between the conduit and the welding powersource enclosure.
The arc welding equipment should be routinely maintained according to themanufacturer’s recommendations. All access and service doors and covers should beclosed and properly fastened when the arc welding equipment is in operation. The sparkgaps of arc striking and stabilising devices should be adjusted and maintained accordingto the manufacturer’s recommendations. The welding cables should be kept as short aspossible and should be positioned close together, running at or close to the floor level.
Bonding of all metallic objects in the surrounding area should be considered. However,metallic objects bonded to the work piece will increase the risk that the operator couldreceive an electric shock by touching these metallic objects and the electrode at thesame time. The operator should be insulated from all such bonded metallic objects.Where the workpiece is not bonded to earth for electrical safety, nor connected to earthbecause of its size and position, for example, ship’s hull or building steelwork, aconnection bonding the workpiece to earth may reduce emissions in some, but not allinstances. Care should be taken to prevent the earthing of the workpiece increasing therisk of injury to users or damage to other electrical equipment. Where necessary, theconnection of the workpiece to earth should be made by a direct connection to theworkpiece, but in some countries where direct connection is not permitted, the bondingshould be achieved by suitable capacitance, selected according to national regulations.Selective screening and shielding of other cables and equipment in the surrounding areamay alleviate problems of interference. Screening of the entire welding area may beconsidered for special applications.
Users should pay attention to electromagnetic interference from welding.

The system is equipped with a slow blow fuse rated for 20А (fuse dimensions: diameter6.3mm - length 32 mm, i.e. diameter / in - length 1 / in) . Please contact yourauthorized dealer with any questions about the 20A fuse.
Additional system safety is provided by a limitation of 68 V imposed on idle voltagebetween torch nozzle and workpiece metal (unit housing) in the absence of a direct arc.The illuminated green SELV indicator on power supply front panel is a signal that voltagebetween torch nozzle and workpiece does not exceed 68 V. A protective tip is used toprotect from electric shock resulting from contact with torch nozzle or cap when voltageon those components may exceed 68 V.

Once the torch is filled with the proper fluid, the power supply is connected, andvoltage is applied to the cathode (the ON button is pressed), the operator can causethe torch to produce an arc by pressing the start button briefly This results in thecathode shorting to the torch nozzle As the start button is released, an electric arc isproduced between the cathode and nozzle Arc energy heats the nozzle, which in turnheats the evaporator, which causes the fluid to heat and turn into steam Steam flowstoward the nozzle outletEscaping from the nozzle, steam compresses the electric arc Arc compressionincreases arc temperature Compressed electric arc heats the steam to ionizationtemperature
under internal pressure . - . bar, i.e. 5.7-17.1 psi
The system has two modes of operation
An electric arc is produced between cathode andnozzle The plasma jet is the only vehicle that transfers energy to the workpiecematerial
The conductive workpiece is part of the cutting(welding) circuit and the electric arc is produced between the workpiece and thecathode inside the plasma jet This causes a significant increase in the amount ofthermal energy transferred to the workpiece
