Continued from NA Welding 7-8/2010 first requirement for quality welding and correct implementation of the design is securely attached to the details together. Most accessible and inexpensive solution for magnetic clamps. Two adjacent edges of the clamp conclude among themselves right angle and rear edges form an angle of 45 . It is a powerful trestle table base kit magnet that firmly adheres details during welding them. Vices are especially handy when welding small parts, trestle table base kit including sheet metal pieces. They are versatile and can find a variety of applications, including serving as support on installation trestle table base kit of various metal structures. With them to grip various steel sections, tubes, rods, etc. The best solution for welding at a right angle or other steel profiles trestle table base kit with different shapes or tubes are shown here of specialized clamps Bessey. Two of them (1) and (2) are intended to be exactly at right angles to the welding. Buck (1) is massive and especially stable, automatically adapts to different welding thicker parts. The second model (2) has a lightweight design. The third clamp (3) is intended for welding of thick parts different angle from 5 to 180 . Vices are extremely stable, capable of pushing a big effort, but screw them has a special trestle table base kit copper coating to repel droplets of molten metal. For larger volume welding, trestle table base kit these clamps totally trestle table base kit zasluzhanvat money (importer instruments Bessey is "Kirov" AD). For welding of profiles would recommend one of two solutions: wire feeder (semiautomatic) MIG / MAG Inverter trestle table base kit DC welding machine with precise control and manage the power and voltage current, allowing welding with minimum currents without danger of sticking electrode (see Fronius TransPocket 1500 SC 12/2009, importer "Kirov" AD). Welding of thin metal sheets and profiles specialty wire feed MIG / MAG welding machines. Not accidentally trestle table base kit spreading to severely restrict the use of oksizhenovite burners Replacement workshops. For years already and semiautomatic welding sell in sector hobby tools. Their prices also makes them eligible for the home workshop. As for ease of use and quality trestle table base kit of welds, which is easier to achieve anyone who once worked with such a machine would be difficult to revert to the old heavy welding transformer that when it has nothing to do with modern inverter 4-5 kilogram welding apparatus. The most common wire feeder semiautomatic work force of welding current between 80 A and 150 A, for welding low and srednovaglerodni steels used protective environment of carbon dioxide. For the welding of aluminum, its alloys and other non-ferrous metals using argon or a mixture of both gases. The most commonly used electrode wire of diameter 0,8 mm and more often - the diameter of 0,6 mm. The main subtlety of successful work with such a device is properly selected combination of the power of the welding current, which depends on the thickness of the welded parts and the optimal speed of wire feeding. In devices with a simple trestle table base kit transformer and not to the inverter converting the strength of the current is changed stepwise in the range indicated, while the wire speed is infinitely variable potentiometer. Insufficient speed causes periodic interruption of the rainbow. When it is higher than necessary, the wire touches the death
