Important safety Instructions Always wear gloves of insulation fabric. Wear suitable clothing, avoid any clothing of synthetic material. Wear heady-duty insulating shoes. Make sure that working area is properly ventilated to prevent accumulation of harmful fumes and toxic smoke Never work in wet places without efficient safety measures against electrical discharges After the work, the electrode has to be taken from the electrode tongs to prevent undesired arc formation. The welding machine should not be used or stored in rain. If the unit is in operation, the electrode tongs should not be put on the unit or other electric appliances as the safety device may get damaged or disconnected when grounded. Do not touch the electrode or another metal object in contact with the electrode while welding is in progress Check that all cables are coated (mainly the contacts with the power cable). The cables with insufficient insulation should be immediately replaced with the same size cables meeting the regulations. Disconnect the unit from the source where not used. The unit may influence supply of other units according to characteristics of the mains. Seek advice from an authority responsible for the power supply whenever in doubt. Assembly and Initial Operation Pic. 2 Handle (Pic. 2): Attach the carrying handle to the unit by putting through the handle two screws and tightening them with a screwdriver. Initial Operation safety Instructions Pic. 3 Check the electrical connection for sufficient protection (16 A) Wear required clothing see fig 3:

Make sure that no other persons stay in working or hazardous area. Make sure that no combustible materials are found in the working area. Operation The unit may be used at a room temperature from 20°C without the thermal protection being put on with the number of reference electrodes n

from warm condition without switching the thermal protection on. The earthing tongs need to be connected with the piece to be welded in a way providing for a good contact. The touch points should be cleaned so that no grease or other impurities that could adversely affect the welding output are present. The unit has a main switch, yellow light indicator, thermal protection and a hand wheel to control the welding current. The control is done with regard to welding current value and electrode diameter. Caution: The indicators will light at overloading only. Thermal protection is provided on the unit to switch off the welding current supply automatically as soon as the inner temperature. As it drops to a value of correct operation, the unit switches on again. Step-by-step Instructions The welding area should be free of any rust and varnish. The electrode is selected by the type of material. It is recommended to test the electrode and the current intensity on scrap at the beginning. Place the electrode ca 2 cm above the starting point. Always use a welding shield, welder’s gloves and protective clothing. Touch the piece and slightly pull the electrode.

Wrong (arc too long) Correct (ca 1 – 1.5 multiple of the electrode diameter) Precise length of the arc is critical as the current and voltage intensity varies. Poor intensity of current makes both the weld and resistance worse. The electrode angle support should be 70-80 degree forward with regard to the piece worked. Too big angle makes the slag slide under the edging material. If the angle is too small, the arc will fluctuate and splash. In either of the cases the wells is porous and weakened 9Wrong Wrong Correct The slag should not be removed before the weld gets cooled. Continue welding of an interrupted weld after the slag is removed.

Wrong Correct The welder should try to keep the arc length constant. As the electrode gets worn, it should typically get nearer. It is recommended to remove the electrode in the direction of the weld to avoid forming a porous crater.
