Automatic spot welders for sale can be found for purchase at a number of different sources throughout the country. Because they have become more popular as time has passed, there is competition from place to place. You will want to make sure that you buy these pieces from a reputable dealer who can provide you with the best possible equipment for the greatest price. The internet is one of the best places to find what you are looking for because there are so many different dealers and websites out there. You will want to take your time and look through all of them carefully to make sure that you are getting the best deal possible.
Two types of automatic spot welding equipment are generally available on the market. One type is the direct current (DC) weld puddle welder which is capable of working with bothaline and cathaline electrodes. The second type is the solenoid based weld puddle welder. Both types of equipment are capable of working with both hot and cold gases and solvents.
The first piece of automatic spot welding equipment is called the tumbler feeder. This is a very simple design with two holes drilled into the top of a standard bowl. Inside the bowl is a solenoid that is able to sense the tension in a welding wire by emitting a pulsating pulse of low amperage. The pulse of amperage feeds the wire an electrode through a feeding coil that feeds the wire a piece of metal that has been ground using alternating electric currents.
There is a mechanical arm that controls the position of the coil over the wire and feeds the wire through the feed tube and then to the tip of the tumbler where it contacts the work piece. When you press the arm it will cause a constant pulse of electrical energy to the work piece making it bend at the same point each time the arm is pressed. Because the work piece moves from side to side this creates a very realistic looking weld. To prevent manual work pieces from slipping out of the machine during the process the feed tube must be connected to a metal sleeve. This is usually adjustable and built into the machine.
The last component of the automatic spot welding equipment is the welding electrodes. There are two types of welding electrodes, the open-ended coil and the closed-end coil. The open-ended coil is capable of heating and touching the work piece in an area that does not require ventilation or cooling as the closed-end coil allows for these functions. There is a heating element built into the tumbler feeder that provides an arc with a high frequency that is necessary to induce heat in the work piece.
Automatic welding equipment is used to weld any variety of different types of metals including stainless steel, aluminum, copper, brass, zinc, tin, steel and many others. There are different types of welds that can be performed with the different types of welding equipment depending upon the type of metal being welded and the welder’s skill. Each type of welding equipment produces a different degree of heat depending upon what the welder is capable of. Basic welding equipment is essential if you are looking to become a welder and start your own business.
