www.engineeringnews.co.nz 35 HEAVY DUTY welding inverter for industrial applications QUALITY WELDING PRODUCTS 0800 145 146 The HELVI Maxitech 380/500 is an incredibly robust and versatile welding inverter that is ideal for heavier industrial applications. It is a high end, powerful machine that utilises the best of European engineering and technology. Previously known as Steady Mig, this range has now fully reverted to the HELVI brand and is handled exclusively in New Zealand by Multi-Mig (NZ). The HELVI Maxitech 380/500 is a microprocessor-controlled, multi-process welding inverter with separate wire feeder suitable for MIG/MAG (manual, synergic), TIG-DC (continuous) and MMA welding. The large 3.3” display shows all the welding parameters, and makes their setting easy and intuitive. In synergic MIG/MAG welding, the microprocessor ensures easy and quick setting of the programs thus always guaranteeing optimal arc stability and high welding quality. MIG-MAG features: continuous – preset synergic curves – storage of custom welding settings – 2T/4T, spot function selection – pre-post gas time regulation – electronic reactance, soft start, burn time, hot start, slope down, crater filler. TIG DC features: lift arc – continuous welding – 2T/4T – Current, final current up/down slope regulation. MMA features – anti-sticking – adjustable hot start and arc force. All parameters can be set both on the generator and on the wire feeder. Options in MIG mode include: root welding, single pulse function, double pulse function, push/pull and spool gun compatibility.

We need to have these roles inside the integrated operations systems, yet others may actually perform them in a secure and controlled way. Through well designed IoT infrastructure, the ability for remote experts to analyse information and real time systems securely from a plant and interact with local staff can be achieved,” he says. The IoT is taking the world by storm and opening new and exciting possibilities to businesses, government and industries. The mining sector also has much to gain from the benefits that IoT can provide, particularly in light of the current market challenges. Through IoT, mining operations can save energy, downtime and costs associated with production and transportation of resources. Remote operations remove people from potentially hazardous situations, improving safety and productivity. The IoT provides the platform for the integration and optimisation of the entire mining supply chain. “On a national scale, for Australia, the benefits that the IoT can deliver are most important because as a country we are not going to win on efficiency gains based on cheaper labour to drive down costs. We are going to use our expertise and knowledge of mining and automation systems to continually improve the most efficient and cost effective mining capability in the world,” says Boland. Together, Rockwell Automation and Cisco have developed a unique value proposition for mining customers to help bridge the gap between mining operations and business systems through network and security products, Converged Plantwide Ethernet (CPwE) reference architectures, training courses, services and solutions. “By developing reference architectures for mining we are reducing risk for our customers. We are developing full guides on how to facilitate convergence of information technology and operational technology so that our customers do not have to do all the heavy lifting and have all the expertise themselves, yet still inherit the capabilities for safe, compliant and sustainable operations and performance,” says Boland. “We are unique in that we develop solutions that leverage our expertise in operational technology, through the Rockwell Automation offering, and then combine this with the deep networking, datacentre and security capabilities of Cisco,” he says. A mine in Canada has established a new technology benchmark for future mines by applying IoT technologies throughout the site. A detailed evaluation process recognised that the Rockwell Automation and Cisco offering was capable of delivering the complete integrated solution. The central operations centre utilises IoT technologies and combines systems monitoring and control with remote equipment control and tracking. The mine deployed the latest advances in controls and communications, including comprehensive Wi-Fi communications for surface and underground phone, data, asset and personnel tracking; and a Radio Frequency Identification-based wireless tracking system, used to create ‘ventilation-on-demand’ underground. Combining operational technology with networking and security capabilities provided the inherent flexibility for the mine to adapt to changing requirements in real time for enhanced optimisation and efficiency. According to Geoff Irvine, mining industry manager at Rockwell Automation, “Using standard Ethernet components really adds significant value in being able to combine control, safety, voice over IP, video, people tracking and also applications such as ventilation on demand.” IoT technologies provide the capability to integrate and analyse data from various processes such as remote sensing of objects and the environment, images from cameras deployed for monitoring and maintenance, scheduling preventative maintenance procedures and monitoring power usage. “Together with Cisco we help customers leverage technology to better gather and analyse data, and transform it into actionable, real time insightful information. By converging information technology (IT) with operational technology (OT) into a single unified architecture, mines can benefit from establishing a ‘Connected Enterprise’ and leveraging the power of this information to optimise operations and take their productivity to the next level,” says Irvine.
