EWM Taurus Steel welding machine aims to reduce electricity and overall costs

GERMAN manufacturer of arc welding technology, EWM, has introduced MIG/MAG welding machines, which include state- of-the-art inverter technology, making them resource-efficient, durable and powerful and helping to reduce costs. According to EWM, comparison calculations show that through the low power consumption alone, companies using an EWM Taurus Steel machine save more than 3,000kWh per year in comparison to a step switch-controlled welding machine. That translates to almost two tonnes less CO 2 and, with an electricity price of 20 cents per kWh, around €600 worth of cost savings a year – and that is just a single machine. For steel and metal-working industries and shipyards, as well as for steel construction companies, there is huge potential for savings with initial procurement costs being rapidly paid off. The Taurus Steel series are suitable for continuous use in three-shift operation and feature machine controls, which are easy to operate, and the welding task can be quickly set up with 100 per cent reproducibility. EWM offers the Taurus Steel in three power variants: the Taurus Steel 400Aand 500Amodels as well as the new Taurus Steel 355 with 350 A output. The 350 and 500 variants boast a duty cycle of 60 per cent at maximum current, while the 400 variant offers a 100 per cent duty cycle for easy welding with full penetration.

EWM already meets the requirements of the new EU Ecodesign Directive and from 1 January 2021, the Directive will ensure that consumers can more easily repair large electrical equipment. From 2023, welding machines in open circuit and during the welding process must not use more than 50kWh each. The aim is to save 167 terawatt hours (TWh) of energy per year by 2030 – as much as is currently consumed by the entire country of Denmark in one year.

New high-frequency tube welder installed and running in ‘record time’ at US company

remained on-site until the tube mill line was running smoothly.

“Universal’s team came through for us at LP Tube. From its engineering team, in-stock replacement parts, to around the clock technical support, Universal is a company we can depend on,” said Scot Edwards of LP Tube Industries. Universal handles US sales and support for ERWTech machinery and carries in-stock high-frequency welders, cold saws and standard replacement parts for customer inspection or immediate purchase.

UNIVERSAL Controls Group and Universal Tube and Rollform recently installed a new ERWTech high- frequency solid-state welder in less than one week from the time of purchase. The new welder was purchased by LP Tube Industries, in Arizona, US to replace a welder on one of its tube mill lines. It was loaded on to a truck the day of purchase and Universal’s team of engineers and field installers went to meet it there shortly after it arrived. When the welder arrived, Universal’s team finished the install promptly and
