SpliceRite Wire Splicer

SpliceRite Wire Splicer SpliceRite Wire Splicer is for the lowest resistance, most reliable electrical connections. This machine creates solid-state metallurgical welds of stranded copper wire bundles of up to 60 sq. mm. in size. Tinned wires up to 35 sq. mm. can be accommodated with our 3500-watt power supply. Sonobond equipment not only produces superior metal welds, it also generates important savings in comparison to such methods as resistance welding and soldering. This makes it win-win for manufacturers because they are able to generate fast, reliable welds while, at the same time, reducing what they have to spend on energy and other production costs. There are also built-in features that can represent meaningful savings to customers. For example, all Sonobond metal spot welders use our unique Wedge-Reed design with heat-treated, tool steel Taper Lock Tips. These are manufactured to last for up to 100,000 welds. When the tips finally do need to be replaced, our units are constructed so that this can be accomplished quickly and easily.

Power Supply for Welding Processes – Arc Spot Welding TIG Spot ...

Selection of a welding process is determined primarily by the characteristics of the joint, the materials involved, their shape and thickness, and joint design. Additionally, production requirements, such as rate and quality, must also be considered. Only after the process has been determined can the proper power supply and accessory equipment be chosen. The process is the primary factor in their selection.

It is our purpose in this article to provide a guide to the selection of power supplies for some of the welding processes, which have come into maturity during the past decade. Once thought of primarily as special processes or processes designed primarily for mass production operations, they are now found in virtually every area of metal fabrication. The increase in the fabrication of once difficult-to-weld metals and the economic and qualitative advantages of the more advanced welding processes are today recognized by even the smallest metal fabricating shops.

Power and control requirements for these processes are somewhat more sophisticated than for conventional shielded metal arc or stick electrode welding. But since the average metallurgist or welding engineer isnt an electrical expert, the selection of proper power supply and the reasons for it can be confusing. The purpose of this article is to eliminate some of this mystery through the examination of the power requirements of production welding processes.

The basic types of power supplies are:

constant current and constant voltage.

Constant Current Power Supply

The conventional stick electrode welder is sometimes called a constant current machine. It is also called a dropper because its voltage drops as welding current increases, thus its volt- ampere output curve  droops .

With the machine turned on but with no arc, and hence no current flowing, it has a relatively high open circuit voltage of 70-80 volts. Generally speaking welding is done at the steeper portions of the curve and this is ideal for manual stick electrode welding.

Arc voltage depends upon the physical length of the arc between the electrode and the work and this can never be held completely constant in manual welding. But, since rate of burn off of filler metal is determined by the amount of current, burn off stays substantially constant if current doesn’t vary.
