Marlin Steel adds wire/strip forming and welding machine

Baltimore-based Marlin Steel has added an Ultimat UMW-100 wire and strip forming and welding machine to its factory floor. The machine uses medium-frequency direct current (MFDC) welding to bond metals quickly and efficiently while minimizing burrs, the company states.

MFDC machines rectify the incoming 50-/60-Hz mains/line power, invert it to 1,000 Hz, and weld at that medium frequency, drawing less line power, providing a weld pulse that can be controlled precisely, and depositing less splatter at the weld site, according to the company.

The machine also creates square, clean-cut wire ends for frames, straight from the wire coil, and then butt welds the ends in one pass through the machine without human input.
