7 Questions and Answers Q. Why should I sell/buy Miller Electric Submerged Arc welding equipment? Miller has taken what they have done for the GMAW and GTAW processes and developed a power source, controllers and wire drive assembly combination that is specific to the SAW (Submerged Arc welding) process. In the past, standard multi-process equipment was used to accommodate this process. Through our research and development it was discovered that these power sources, although able to weld the SAW process, were not optimized to run as good as our competition. Much work has been done with arc development to assure our customers will be getting the performance they demand with the SAW process. There is now an alternative to the old standbys when it comes to the SAW process. Q. Does Miller have a full offering for the Submerged Arc process? Miller offers weld controllers, wire drive assembly, power sources, flux hoppers and torches all developed together to offer you the best performance from a system approach. When used in conjunction with each other Miller can assure you that these items have been tested together to optimize their performance. Q. Can Miller Submerged Arc equipment be used with equipment other then Miller? No: Because of the optimized performance that a Miller system offers we do not recommend mixing other manufacturers power sources, controllers or wire drive assemblies. Q. Why do I need to use sense leads? Sense leads are critical to obtaining correct arc voltage to optimize the system. When sense leads are not used the system supplies the pre-set voltage at the studs of the power source, not at the arc. Voltage drop in the work piece and cables is not accounted for and therefore a lower voltage than what is preset will be delivered to the arc and can cause poor arc performance. Q. Does it really matter where I hook the sense leads up? Yes: The proper placement of sense leads is as important as using them. The proper placement is covered in the owner s manuals of the power sources and controllers. Q. Why is the sense lead connection only on the power source now? This allows the communication between the power source and control to be faster and more accurate. This also promotes good starts. Q. What power sources are recommended to go along with the Miller controls? DC Power Sources Part Number Sub Arc DC #9 8 Sub Arc DC 8 #9 Sub Arc DC #9 Sub Arc DC #9 with CE AC/DC Power Sources Summit Arc #9 Summit Arc #9 (/ Hz, V) Q. Why are the Deltaweld and Invision no longer recommended? They do not have the capability to hook up sense leads externally for accurate arc voltage. The power sources mentioned above have a terminal strip to accommodate this sense lead hookup. Q. When should the Summit Arc / be recommended? The Summit Arc / can be used for a trail arc in a standard tandem setup. The Summit Arc is also an AC/DC, CC/CV power source with many advantages over a standard DC power source. Please call Miller Electric at and ask for a Submerged Arc specialist to help you with your decision. Q. What is a RAD- and RAD-8? The RAD stands for right angle drive and it is Miller s wire drive assembly for wire diameters from 1/1 1/ in. The and 8 represent the highest wire feed speed of each motor. The RAD- is recommended for most sub arc applications using wires larger than / in ( mm). Q. Does Miller Electric have fluxes and wire for Submerged Arc welding? No they do not. Q. What fluxes will work with the Miller Submerged Arc equipment then? If a flux and wire combination is being used with current equipment, that same combination can be used with the Miller Electric equipment. If you are looking for a new flux and wire, or increased deposition is a consideration, then the Hobart/Tri-Mark consumables should be considered. Please contact them through your local distributor or call Hobart at 9--1 and ask for their recommendations. Q. Can I use the Miller flux hopper with preheated flux? Yes. We have improved the design of the flux hopper to be able to accommodate hot flux whether preheated or reclaiming directly after the weld. The hopper also comes standard with an electric valve that can be controlled manually or from the controller.
