In a country house there are always minor work with the national electric welding. To all the time not to ask Uncle Grisha, a welder, you can try to learn the profession itself. That's the beginning of a couple suggestions to help you in this difficult matter. Choose a welder. Try to identify the optimum welding machine for use at home, where you can learn welding, and which do not want to change later. First, he must take up little space, so as not to occupy much space in the pantry. Second, its weight must not exceed the bar in 10 – 15 pounds, so as not tore muscles of the back, dragging from place in place. Learn to work welder is recommended for models of equipment, staffed control of electric current.
The most important condition for welding, is to provide a confident electric arc, which depends on the welding current in the welding electrode. Welding electrodes of different manufacturers, moisture coating on them, the diameter of the wire and the connected metal – from This depends on the welding current selection. Devices with built-in manual controls the welding current, greatly simplify the setup process. Closest to these requests fall pulse welding Russian equipment – inverters. Their size is not larger than a box of shoes, and weight of other vehicles just over 3 pounds.
Some models are equipped with electric arc ignition functions and protect it from overheating. The cost of the pulse inverter does not exceed the cost budget models of welding transformers. Precautions for welding equipment. You bought a welding transformer, now we have to protect your hands and face from ultraviolet radiation of the arc and spray the liquid metal. Special protective mask or shield welder requires mandatory. Korotkovremennoe radiation from the arc on your face is akin to simultaneous action of several quartz lamps. So, the use of welding machines without special welding mask is fraught with, at best, a bunch of sunbeams in the eyes, but you can get a nasty injury: burns of the cornea and into the hospital. Do not spare money and buy a welding jacket, pants and gloves made of solid material. They are designed to protect your body from droplets of molten metal, which is great variety in welding time. Getting to welding. Pytates not the first time to cook anything complicated, will transfer a lot of material. Take a few unnecessary pieces of iron of various sizes and thicknesses. Find a place where there is no contact with easily flammable combustible materials, set there workbench and vise and train. Get used to cook electrode diameter of 2.5 – 3mm. They are suitable for all major types of welding in the flat and garage, are optimal for domestic welding machine. To be effective manual electrode welding of large diameter is necessary industrial unit, which is absolutely not suitable for use with home power grid. However, if there is work with thin sheets of metal, semi-automatic welding is better to buy, where the electrode will serve Turkish welding wire.
