Spot Welding Machine Basics

Spot Welding is often used when you need small cross section welds from the welding of two pieces of metal. Welders are able to repeat the process as many times over as they want until they have created a perfect weld. They simply need to look at the current size of their workplace. Repeating spot welding will also strengthen your welds strength, which makes them last much longer. In addition, because they are spot welds, they are very easy to remove and clean. These machines can be operated with either a joystick or a mouse, depending on your personal preference.

The electrical energy that is given off when you place an arc between two metal pieces is referred to as the flux, and the lower the flux, the easier the arc is to create. Fuses are measured in units called amperes, and a lower ampere means that the arc is more difficult to create. Most welders use a combination of filler metal (the thing that makes the weld) and a piece of sheet metal (this acts as a flux point). When you place a spark in the middle of this, which will create a conductive energy that joins the two pieces, you create a perfect spot welding machine.

There are a variety of different heat sources that welders use in their machines. Some of the most common ones are a torch with a tip made out of steel (sometimes referred to as ‘torch tapers’), gas, electric and cordless. The type of filler material that you use in spot welding machines will determine the source of heat that is used. For instance, if you were to weld sheet metals that are not sensitive to high temperatures, using a torch with a low temperature setting is most effective. This is why most welders will have multiple spares, some of which are specifically designed for welding thinner materials, and others for larger sheet metals.

One of the most popular techniques that welders use is a continuous-permanent arc, or CPA. This is where the arc is maintained on one side of the sheet while it continuously feeds through the welding current to the other side. As the current feeds through the sheets, the areas that are not covered become filled in with the welding current. This allows the welder to continue feeding until there are no gaps in the metal sheets.

Gaps in the metal sheets allow heat to escape, which means that the welder has to stop feeding, or keep feeding constantly to keep the arc going. Gaps can often lead to a ‘feedback’ effect where the welder begins to build up stress in the welded workpiece. As a result, the welder may start to feel the strain in the wrists and arms, as well as in the fingers and hands. This is caused by the continued feeding of the welding current between the welded workpiece and the welding electrodes. This strain can be very dangerous and is often easily preventable with the use of welding gloves and a welding shield.

Other machines include the pulse welders, which again use the principle of continuous current feeding between two conductors, but the feed is constant and directed to one side of the sheet instead of to the other. A pulse gun uses compressed gas to generate a concentrated stream of welding current, similar to a spray of paint. The only difference between the three types of machines is how they use the energy produced to do their job; all welding machines are designed to produce the same amount of energy, but some are better than others at generating this energy in a concentrated beam.
