The Benefits of Using Tip Dressers to Reduce Welding Cost and Improve weld quality

Stationary electrodes tip dressers are among the first machines that made the portable automatic milling of electrodes popular way back in the late nineteenth century. Over the intervening years, they’ve been extensively modified and adapted for the modern requirements of industrial users. One of the most recent developments in this arena was the invention of the Spot Welding Gun. Here are some features of the Tip Dresser that you might like to consider when shopping for one for your factory or workshop.

Tip Dresser

This type of pneumatic tip dresser has the versatility of a lathe with a large table and the speed and efficiency of a smaller electric motor. The difference is in the power source. The Stationary Electrodes requires an electrical connection through the fitting of a cap to the larger electric motor which is placed in a holding chamber. It is controlled by a variable speed electric motor, which is controlled by the user through the use of a hand-held controller or a dial. A variable pulse width setting controls the arc energy.

This type of pneumatic tip dresser is very versatile and widely used in welding situations where high production with little or no downtime is desired. It is generally used as an electrode cutter but can also cut other products such as tubing. Unlike a true welding cutter which requires a dedicated pipe or a transfer stand for storage, a pneumatic tip dresser can be conveniently stored on a shelf or mounted on a cart. The unit is fully equipped to handle either gas or electric cutting. It has a pair of metal cutting pads positioned over a heated rail. When a gas or an electric current is applied to these pads, it causes a chemical reaction that melts the metal that is being cut, so that the heated rail pulls the pad away from the welding area.

Variable speed transformers (VSP) is the power supply units for tip dresser electrodes. A voltage regulated high output transformer supplies power from the transformer to the VSP and to the accessory interfaces. Many accessory interfaces are available to attach different sizes and types of electrodes.

In most cases the VSP is coupled to an electrical motor to operate the electrical drive. The electrical drive enables the tip units to rotate at various speeds. The speed of the rotating tip units varies according to the application needs. There is a limit, however, as to how fast a unit can rotate. The tip dresser may have up to seven different settings from which to choose from for cutting any type of metal.

The tip dresser assists the welder in continually striving for the highest quality products. It gives the welder a much easier way to work with these high quality materials. It also eliminates the need to have two units to hold one or two different sizes of electrodes.
