Welding systems with remote control of power source
- May 12, 2015
The new multiprocess XMT ArcReach systems from Miller Electric Mfg. Co. have been designed to reduce downtime, costs and exposure to safety hazards by allowing welding operators to set voltage at the weld joint without the use of control cables.
This capability minimizes unnecessary trips to the power source, allowing for more arc-on time and greater productivity. By providing control of voltage at the weld joint, the new systems also reduce the opportunity for trips, slips or falls on the jobsite; encourage best-practice weld settings and weld techniques; and lessen operator fatigue associated with excessive walking to and from the power source.
The XMT 350 VS ArcReach (for 3- or 1-phase power) and XMT 450 VS ArcReach (for 3-phase power) are both ideal for industries such as shipbuilding and construction, where welding operators work at significant distances from the power source. Both systems are compatible with Miller SuitCase® X-TREME™ 12 VS or 8 VS ArcReach feeders, and provide multiprocess welding capabilities, including MIG (GMAW), Stick (SMAW), TIG (GMAW) and Flux-Cored (FCAW), and Air Carbon Arc Gouging (CAC-A).
Greater productivity, reduced costs
In addition to generating more arc-on time by reducing trips to the power source, the XMT ArcReach systems help reduce downtime to address operator fatigue so welding operators are able to spend more time welding — enhancing productivity. The XMT ArcReach systems also reduce downtime for troubleshooting welding system problems resulting from damaged control cables, as well as the expense of purchasing, maintaining, repairing and replacing control cables.
The XMT ArcReach systems save time by eliminating the need to access and reconfigure power source settings after use. When a welding operator connects the ArcReach-equipped feeder to the XMT power source, the panel setting automatically converts to MIG/FCAW (with gas) if it detects an electrode positive connection or FCAW (no gas) if it detects an electrode negative connection. Disconnecting the feeder restores the power source’s original panel settings, making it easy for the welding operator to switch processes right at the weld joint.
The ArcReach systems provide remote override of weld process and arc voltage at the power supply, which prevents other welding operators from making setting changes. The welding operator can precisely set arc voltage at the feeder and monitor the actual arc voltage and current delivered to the weld using the digital meters on the feeder. Having this control at the weld joint makes it easier to adhere to weld procedures and prevents welding operators from settling for less than optimal settings, resulting in more consistent and higher weld quality.
