Cascading

"Cascade" welding is used in a variety of applications: large sheet metal welding, cross wire welding, bracket to sheet metal, electronic cabinets, and furniture just to name a few.

Cascade welding occurs when a control using just one weld schedule, initiates a single air valve to close multiple electrodes, and sequentially fires two or more SCR's. A number of variations can be applied to this methodology enabling end users to improve the welding process, and reduce maintenance and operating costs. This Connection explains how and why Cascade welding is used, how it can be improved, and the benefits these improvements will realize.

Cascading allows for even power distribution such that each phase of the line can be fired in a sequence that minimizes power requirements. This is particularly important in systems that are already at their available power limits. Additionally, not all buss systems are designed to handle such high power all at once.
