In this presentation, WeldComputer Founder Bob Cohen explains how resistance welding operations can increase flash welding performance while reducing energy utilization. You will learn how to: increase the flashing capability of your machine, increase flashing consistency, increase upset consistency, provide proof of flashing and upset consistency of every weld, and reduce energy demand and flicker on the power line. […]
A manufacturer contacted us recently with a problem: Their welding performance looked good and their machine performing well. But each aluminum weld created had a dark spot that was noticeable. They were concerned about the impact this cosmetic defect was having on the appearance of their product, and the perception that it could be impacting […]
Abraham Lincoln once said, “give me six hours to chop down a tree, and I will spend the first four sharpening the axe.” While Lincoln’s quote highlights the importance of preparation, I see another lesson – ensuring you have the optimal tooling for the job. As I recount on my 30+ years in the industry, […]
We all know that your resistance welding control needs to check the boxes for all the core criteria when it comes to your welding operation; ensuring weld consistency, weld quality, and low maintenance are at the top of the list. But sometimes, things that may not seem obvious can show up as hidden (or at […]
Get more out of your existing resistance welding machine by upgrading your control. If you are in the market for a new resistance welding machine, this article might save you tens of thousands of dollars. Our team collaborates with resistance welding manufacturers to help solve problems of reliability and inconsistent weld performance. Often, the conversation […]
For resistance spot welding, resistance projection welding, and resistance seam welding, the RMS current needed to weld a specific material of a specific thickness will be similar for MFDC as for AC. If all things are considered equal, where the only variable is the weld transformer type, the same KVA MFDC or AC transformer is […]

Benefits include regulating weld consistency, operating at fast production speeds, and improving weld qualityBy Robert K. Cohen Making a gas-tight seal with a seam welding machine involves making a series of overlapping spots. Each spot produced should be a fully formed nugget that is free of expulsion. Using too little heat produces an undersized spot, which can cause a leak. Using too much heat […]
