The welding industry has developed a lot, and a lot of equipment and tools are available and still more tools are to be introduced. To become a good welder or to become a famous entrepreneur in welding industry, knowledge about the welding tools is must and we should update our mind and should be aware of the welding tools. Let us see the different types of welding tools in the following lines.

Welding products:
Under this category we are going to see the different types welding products and its uses. There are different types of welding such as mig, tig, stick and submerged arc, each type of welding uses different tools. For welding industries and workers, it is always better to have equipment which best suits and do all kinds of work. For mig welder, there is a welding product which meets almost all repair needs. Inverter welding machines are the one which suits for all mig welding work and at present single phase machines is there which are convenient and portable and can go anywhere you need. You need not run back for more wire; it has a 12lb roll capacity with optional drive rolls. It is used in general repair, automotive, motor sports, agricultural and more.

Tig welder products:
If you are a tig welder, then know about the power tig series that is focused on user convenience and it exists in different types such as power tig 200DX, 250EX, 315DX, 225LX and power 1-tig 200. It is designed to weld any types of steel and stainless materials and it is easy to repair in the field and garage, and each power tig series can weld aluminum of different thickness and used in general repair, light industrial and light fabrication. Power tig 250EX and power tig 315DX are the three phase machines and others are single phase machines.

Power arc welders:
It is a product made for stick welders and it can be used in any place where you have 220v single phase current. It exists in two types such as power arc 160 and power arc 200, power arc 160 has the following features such as smooth dc arc, low power consumption, high duty cycle with digital display and adaptive arc force control. It is used in welding repair, garage, factory, shipyard and pipeline and used to weld steel, aluminum and cast iron. Power arc 200 also has the same features as that of 160 series, but the difference is power arc 200 has 200A rated output whereas the former one has 160A rated output.

Multi purpose units:
Buying separate units for welding may increase your budget, and do you want the unit which performs multi function purpose? Then, go for multi purpose units which perform all the welding process and also perform welding and cutting. These units exists in six types such as powerultra 164, 185, 205 and powerpro 205, 226 and 256. Each unit has some maximum cut thickness and has rated plasma output and weld output and used in industrial, HVAC, repair, motor sports, fabrication and more.

A pulley, also called a sheave or a drum, is a mechanism composed of a wheel on an axle or shaft that may have a groove between two flanges around its circumference. Maybe most of you are not familiar with it, but it is a very important mechanical part. There is usually a rope, cable, belt, or chain runs over the wheel and inside the groove if present.

What are the pulleys used for? Generally, they are used to change the direction of an applied force, transmit rotational motion, or realize a mechanical advantage in either a linear or rotational system of motion. They can be used in ships, cars, and many other places.

Now, I’d like to introduce a basic usage of pulleys. Most of you know something about cars, but are you knowledgeable about car components? I think few of you can nod your head. Among various components, pulleys can be applied to improve the efficiency of performance. But how do pulleys work? Most of you know the importance of the engine. In a car, the engine may provide more power than just the wheels. Therefore, it is very necessary to improve the working efficiency of the engine. Doing this requires the usage of pulleys. For example, the engine works with the help of a belt and pulley system. Besides, when you wish to do up your car, you should learn something about engine pulleys. This kind of pulleys may sound unfamiliar to most of people. The engine has several belts that drive various parts of the engine, while belts need pulleys so that they can be held in place and drive the parts of the engine properly.

Two or more pulleys together are called a block and tackle. It is also call the rope and pulley systems. The simplest theory of operation for a pulley system assumes that the pulleys and lines are weightless, and that there is no energy loss due to friction. It is also assumed that the lines do not stretch.

Although the above analysis is not complete enough for you to know well about pulleys, you can still learn the basic information about it. I think it will be of some help for you to bear this information in mind.
