x Neighbouring workplaces are to be screened off to provide protection against radiation. x When welding inside rooms and buildings sufficient ventilation must be ensured. A A Fire Danger! The arc temperature is approx. 2400 °C. Before starting to weld observe the following information: x Remove all combustible materials and objects within a radius of 5 m from the welding point. x Materials that can not be removed within a 5 m radius must be protected by covering with sheet metal, wet cloths etc. x Any wall openings, cracks and the like must be covered or sealed respectively, to prevent uncontrolled flying of sparks. x Keep fire extinguishing equipment such as fire extinguisher, water pale etc. at hand. x Keep in mind that by heat dissipation from the welding point a fire may be started on covered parts or in other rooms respectively. x After completion of the welding work check the vicinity of the welding point several times within a period of 6 – 8 hours for heat conduction, glowing combustion spots, hidden seats of fire etc. Handling of Shielding Gas Cylinders x Observe all applicable regulations pertaining to the handling of gas cylinders. Because of the dangerously high internal pressure (up to 200 bar) shielding gas cylinders are to be specially protected against mechanical damage, falling over or falling down, heating up (max. 50°C), prolonged radiation by sunlight and heavy frost. x When the welding machine is equipped with a gas cylinder too large in size this can cause, on uneven ground, the welding machine to fall over. To prevent subsequent damage to the welding machine or the gas cylinder, use only proper size gas cylinders (10l / 20l cylinders). x Have cylinders refilled only by authorised filling stations. Electrical Hazards x The connection to power mains and servicing of the welding machine is to be done in accordance with VDE regulations or other standards applicable in your area. x Ensure proper protective bonding of the supply circuit. x Ensure proper protective bonding of the workbench. x Any service or maintenance work must only be carried out by qualified personnel. x Replace defective or damaged parts of torch or torch leads without delay. x The unit must only be connected to an earthed outlet as a matter of principle. Only connections, including outlets and extension cables with an earthed plug, having an earth conductor and installed by a qualified electrician, are permitted. x The fuse protection of the supply circuit must be in accordance with local regulations. According to these regulations fuses or miniature circuit breakers respectively, suitable for the conductor cross section, must be installed. Installation of a fuse with to high an ampere rating may cause line fire and subsequent fire damage to the building. x Replace damaged torch insulation and welding cables without delay. x Replacement of a damaged power cable, plug etc. and repairs to the electrical components of the welding machine must be left to a qualified electrician. x Welding torches must not be held in an armlock, or in such way that electricity can run through the body. MIG/MAG 140/160 Switch the unit off for longer work breaks. Unplug when work is completed and before relocating the unit. In case of accidents separate the welding power source at once from the power supply. General Machine Description The MIG/MAG welding machine consists of a transformer (static characteristic curve), a series-connected silicon rectifier, a welding circuit choke, and a wire feed unit. The welding machine is suitable for the welding of different electrode wires (e.g. steel, see "Technical Specifications") under a shielding gas cover (CO2, mixed gas and argon). The machine is fan cooled and has an overload protection. Symbols Used Danger! Disregard of the following warnings could cause serious personal injury or material damage. Read operating instructions before initial operation Wire feed speed Do not use in rain. Welding machine suitable for welding in environments with an increased electrical hazard.
