applied in large bore boiler pipe repairs, workshop build-up and cladding, as well as in-situ repair welding and replacement welds in power generation boilers and pet- rochemical gasifier plants,” says Pieterse. “Welding parameters can be pro- grammed and stored directly onto the SmartFeeder, or welders can store their own programs and settings on a memory card. These optimised settings are then im- mediately available to the welders as soon as their shift starts, and there is no need to spend valuable production time optimis- ing the settings at the start of each shift,” continuous Dewald Bodenstein. The latest Miller addition to this system is a remote induction-heater system, which offers fast, safe, and precise pre-weld heating of up to 315 °C. The system is powered via the welding cables from the same multi-process welding power source used with the remote, the suitcase feeder or the SmartFeeder. A separate induction power supply is no longer required. Once pre-heating is complete, the welder can immediately start welding, with an abso- lute minimum of setup delay and without the need to move away from their onsite welding station. Miller ArcReach technology, for which Af- rox is the exclusive agency, combined with the GasReach MUPP shielding gas delivery system, offers an ideal Afrox 360° solu- tion. The combination of Miller and Afrox equipment and quality delivers advanced technology, first-class consumables, and high-purity shielding gases directly to where they are used, eliminating the need to return to the power source to make pa- rameter adjustments or to manage numer- ous shielding gas cylinders at the point of work. This provides optimum productivity when welding. ‘Don’t walk, weld’ is the key Miller phrase used to describe the benefits of ArcReach. This highlights the time-saving and safety advantages that result from
The class-leading Afrox Saffire Gas Equipment range and Afrox’s 360° gas safety solution training bring peace of mind to any manager or business owner. eliminating the need for welders to walk to and from the power source and their welding stations. ArcReach systems are powered by the extraordinarily robust XMT 350 FieldPro with Polarity Reversing technology, which includes Auto-Line, which automatically adjusts to any input voltage from 208 V to 565 V. The same power source can be used for all the different ArcReach combinations described above. Initially launched in the early 1990s, the Miller XMT power source technology has undergone continual im- provement and updates, and the power sources are well known for their reliability and robustness. The ArcReach technology can also be used with some of the well- known and reliable Miller engine drives, without losing any of the high-end control capability. “The Afrox MI Team has been using its 360° Application Solutions Programme to solve real customer problems, thereby adding value to their operations over long periods of time. By surveying a customer site, we can extract valuable information to create a value proposition that addresses problems and enhances profitability. Fol- lowing implementation, this is supported with ongoing customer support,” assures Johann Pieterse. “The Miller ArcReach and Afrox Gas- Reach combination offers new and unique opportunities to enhance welding profit- ability and safety across a wide range of industries, elevating modern welding technology to levels and locations previ- ously unimaginable. ”Interested?

Polarity Reversing technology auto- matically changes the polarity from DCEN to DCEP, and the current control is done directly on the remote. Likewise, if the welder needs to switch to GMAW or FCAW, the welding cables can be connected to an ArcReach suitcase feeder, while the multi-process power source re- mains safely out of the way from the work- station. ArcReach suitcase feeders are also available in smaller 8-inch versions, which are ideally suited for use in workspaces with access restrictions. Maximum benefit and cost savings are ultimately realised when the Miller ArcReach SmartFeeder is connected to the power source, as this allows for open root with RMD fill and cap welding to be performed with the same equipment, wire and shielding gas. In addition, RMD eliminates the need for a hot pass, resulting in a process that often replaces the conventional GTAW process for large-bore pipe welding, delivering five times faster weld deposits compared to a traditional GTAW root and hot pass weld sequence. Once the root has been welded, the welder can immediately switch the wire feeder to GMAW-P mode and begin rapidly filling the weld, with capping done using the same mode. The efficient process is ideally suited for welding with solid or metal-cored wire, which eliminates slag formation and slag inclusions. Using metal-cored wires adds even more productivity gains and cost- saving benefits, so it is recommended whenever a suitable consumable is avail- able. Compared to conventional processes, RMD and GMAW technology is at least three times faster than traditional GTAW and SMAW, with productivity savings often exceeding 80% per kilogram of deposited weld metal. “The procedures have been successfully
