1 INSTALLATION This machine must be used for welding only. It must not be used to defrost pipes. It is also essential to pay special attention to the chapter on SAFETY PRECAUTIONS. The symbols next to certain paragraphs indicate points requiring extra attention, practical advice or simple information. This manual must be stored carefully in a place familiar to everyone involved in using the machine. It must be consulted whenever doubts arise and be kept for the entire life-span of the machine; it will also be used for ordering replacement parts. 1.1 PLACEMENT Unpack the machine and place it in an adequately ventilated area, dust-free if possible, taking care not to block the air intake and outlet from the cooling slots. CAUTION: REDUCED AIR CIRCULATION causes overheating and could damage internal parts. Keep at least 500 mm of free space around the machine. Never place any filtering device over the air intake points of this welding machine. The warranty shall become void if any type of filtering device is used. Mount the parts supplied with the machine as shown in the figure 1. Fig. 1 2 DESCRIPTION OF THE MACHINE A) Switch Turns the machine on and off, and also regulates the welding voltage range. B) Setting knob This knob serves to adjust the welding wire speed. C) Earth cable D) Yellow LED Lights only when the thermostat is tripped and interrupts the machine operation. E) Green LED Indicates that the machine is turned on. F) Welding torch G) Handle Must not be used to lift the machine. Fig. 2 3 GENERAL DESCRIPTIONS 3.1 SPECIFICATIONS This welding machine allows welding of soft steel, stainless steel and aluminium. 3.2 EXPLANATION OF TECHNICAL SPECIFICATIONS N° Serial number which must be stated when asking for information or servicing related to this machine. IEC 60974-1 The welding machine is manufactured according EN 50199 to these international standards. Single-phase Transformer - Rectifier MIG/MAG. Suitable for continuous wire welding I2 max Unconventional welding current. The value represents the maximum level that can be obtained in welding. Uo Secondary no-load voltage. The duty-cycle expresses the percentage of 10 minutes during which the welding machine can operate at a determined current level without overheating: e.g. X=60% at I2=100 A. This means that the welding machine can weld with a current I2 = 100A for 6 minutes out of 10, i.e. 60%. I2 Welding current U2 Secondary voltage with welding current I U1 Nominal supply voltage at the rated frequency. I1 max. This is the maximum value of the absorbed current. I1 eff. This is the maximum value of the actual absorbed current. Ip 21 Grade of protection of the case. Grade 1 as a second number means that this unit is not fit for working in the rain. S Fit for working in high-risk areas. 3.3 DESCRIPTION OF PROTECTION This device is protected by a normally closed thermostat on the power transformer. When the thermostat is tripped the machine stops welding, while the motor-driven fan continues to run and the yellow LED lights. After it has been tripped, wait a few minutes to allow the generator to cool down. INSTALLATION The machine must be installed by skilled personnel. All connections must be made in compliance with current regulations and in full respect of safety laws. Make sure that the wire diameter corresponds to the one indicated on the roller, and mount the wire reel. Make sure that the welding wire passes through the groove in the small roller 7. Before connecting the power cable 23, make sure that the power voltage corresponds to that of the welding machine, then: a) for permanent connection to the power mains without a plug, you must insert a main switch having a suitable capacity in compliance with the rated specifications. b) for a plug-socket connection, use a plug having a suitable capacity in compliance with the rated specifications. In this case the plug must be used to completely disconnect the machine from the mains, after setting the switch 47 to “O” (off). The yellow-green wire must be connected to the earth terminal. Connect the earth clamp 37 to the part to be welded. The welding circuit must not be deliberately placed in direct or indirect contact with the protection wire except in the workpiece. If the workpiece is deliberately grounded using the protection wire, the connection must be as direct as possible, using a wire at least as large as the welding current return wire, and connected to the workpiece at the same point as the return wire, using the return wire clamp or a second grounding clamp placed next to it. All precautions must be taken to avoid stray welding currents. Turn the machine on using the switch 47. Remove the tapered gas tip 44 by turning it clockwise. Unscrew the contact tip 43. Do not press the torch trigger until you have read the instructions carefully. It is important to make sure the machine is turned off whenever changing the wire reel and wire roller, to prevent the wire feed motor from starting acc...
