If you have an application that requires you to work with thinner materials, such as copper, you will find that you can benefit from the use of a Tissue Dryer. A Tissue Dryer is a specialized dryer that has a special type of fan that draws air through the metal surface and heats it to a temperature suitable for working with thinner materials. The special fan allows the air to be directed to the work piece without being heated by the atmosphere around it. Once the material has cooled to the temperature desired by the user, it can then be trimmed by hand until it has the correct profile.
Tip dressers typically have circular rotating cutting devices which are used to manually clear and shape copper electrode tips following use in industrial welding operations. R SW tips are typically dressed on their own to have a cylindrical outer wall which terminates at an inner flat disc. An electrical connection is made between the outer cylindrical surface and the inside flat. Electrical wires or cable are usually run along the wire to serve as conductors. Typically, this type of dresser has a clutch system to automatically control the temperature so as to not wear the thinning tip dresser down to its limits.
When a wire becomes overheated, it can cause damage to the tip dressing. This is why tip dressers should be maintained to ensure that they do their job in the long run. A Tissue Dryer works by circulating air in and around the electrode. Any excess moisture will be removed by a fan as the temperature rises. If the moisture still exists, the ceramic coating on the tip dressing can become scratched and stripped off.
There are two types of tip dresser designs: electroplating and resistive spot welding tip dressers. Electroplating is the most common and the more popular design. The resistance spot welding tip dressers, however, are less common. They are called resistive because they work by feeding the electrode tips through a very small area. This allows the tip to create a temporary magnetic field, which imparts power.
With resistive tip dressers, you will need to manually add the electrode tips to each piece. The resistance spot welding tip dresser automatically applies the welding flux to each one. This means that you will not have to worry about applying flux separately. The disadvantage of using this type of tip dresser is that the constant contact with flux may cause wear and tear on some of your electrodes. This is not a problem with tester tip dressers, which do not require any contact with flux.
The last type of tip dresser that we will discuss is the circumferential shoulder. Circular or rectangular, the circumferential shoulder is designed for use with mig welder machines, specifically MIG welding guns. Since it has no external feed, it only requires a continuous supply of gas. In the MIG welding process, the fabricator places the welding arm in the cross section of the material; the resulting arc is the arc that cuts the material.
