MILLER PIPEPRO™ MULTI-PROCESS WELDING SYSTEM IMPROVES PIPE WELDING PRODUCTIVITY BY 25 PERCENT OR MORE
- Offers superior arc performance in all processes
- Enables less-experienced operators to make code-quality welds
- Advanced welding technology also user friendly
PipePro 450 with feeder
APPLETON, Wis., January 9, 2006—Miller Electric Mfg. Co. recently introduced its PipePro™ Multi-Process Welding System designed to improve welding productivity in process piping for offshore piping and on-shore piping and pipe fabrication applications. The system features the PipePro 450 RFC (Root-Fill-Cap) power source, PipePro 12RC SuitCase™ or PipePro bench-style feeders and Bernard® PipeWorx™ Guns.
The PipePro Multi-Process Welding System features the patented advanced welding processes of RMD™ (Regulated Metal Deposition, a modified short circuiting processes) designed for root pass welds, and Pro-Pulse™ (which is easier to use than conventional pulse in out-of-position pipe welding applications). Providing unmatched versatility for field and shop fabrications, the PipePro Welding System offers superior arc performance in all processes: Stick, TIG, MIG, FCAW, Air Carbon Arc Cutting and Gouging. Operators are able to select the welding process best suited for the application.
“The PipePro 450 RFC with RMD and Pro-Pulse makes it easier for less-skilled operators to produce welds that meet API, AWS, ASME and other code requirements,” says Mike Roth, marketing manager GPS group, Miller Electric Mfg. Co.
More user-friendly than competitive systems, operators can become proficient with the RMD Pro process much faster than they can with the TIG or Stick processes. As a result, the PipePro 450 RFC may help alleviate the chronic shortage of qualified welding operators by enabling fabricators to train people in less time. Yet, the PipePro 450 RFC offers superior arc performance in all processes for exception job-site versatility.
In addition, Roth says that, “Substituting RMD Pro for TIG and Stick can conservatively improve productivity by 25 percent or more. Cycle time improvements result from increased travel speed, improved deposition rates, fewer starts and stops and, in the case of Stick welding, significantly less clean-up time. Pipe fabricators facing tight deadlines or cuts in operating costs can’t afford to overlook the long-term value of PipePro 450 RFC.”
The PipePro 450 has an output of 450 amps/44 volts at 100 percent duty cycle. It measures 22 x 15.5 W x 41 H (inches), weighs 163 lbs. and features Miller’s exclusive Auto-Line™ primary power management technology.
Auto-Line provides the flexibility to accept any type of primary power (190 to 630 volt, single- or three-phase, 50 or 60 Hz) without any physical linking mechanisms. As a result, global companies can standardize on a single system to simplify inventory. Auto-Line also enhances weld quality and may reduce rework in fluctuating power environments because it maintains a rock-steady arc despite primary power variations within a 190 to 630 volt range.
Revolutionary Concept
The PipePro RFC provides the benefits of advanced welding processes without a complex operator interface and extensive set-up. To begin welding with RMD Pro or Pro-Pulse, operators enter the wire type, wire diameter, gas combination and process desired. The PipePro 450 RFC then selects the optimum welding parameters from its vast library of application programs. After that, the operator sets the desired wire feed speed to match the application and begins welding. The system automatically maintains all other variables.
The PipePro RFC is managed through the PipePro System Manager Package, which features Miller Program Manager Palm™ OS-based software that turns the Palm PDA into a storage device and remote pendant control for all PipePro systems. Program and configuration files can easily be transferred from machine to machine, or machine to computer. The powerful, intuitive interface even includes a password protection lockout feature to protect programs from changes by unauthorized personnel.
RMD Pro and Pro-Pulse
The RMD Pro and Pro-Pulse processes solve many pipe welding problems and productivity limitations (see below).

RMD™ Pro is a modified short circuit transfer MIG process (GMAW) that precisely controls the electrode current during all phases of the droplet transfer. RMD Pro provides a more stable puddle that produces excellent side wall fusion and tie-ins, makes it easier for the welder to produce high quality root passes on pipe and accommodates poor fit-ups without difficulty. Miller designed the Pipe Pro’s RMD Pro programs specifically for open-root pipe joints in carbon steel, chrome-moly steel and stainless steel using solid and metal cored wires.
Compared to traditional and competitive pulsed MIG processes, Pro-Pulse provides shorter arc lengths along with a more focused arc column, which in turn provides significantly improved puddle control and arc stability for out-of-position pipe welding. The more focused arc column also improves welding in narrow joints without arc wandering, making it ideal for fill and cap applications.
The PipePro 12RC SuitCase feeder provides a durable solution for field welding, weighs 25.5 lbs. (empty) and offers remote amperage and voltage control and a digital meter to precisely set welding parameters. For shop welding, the PipePro single and dual feeders are specifically designed to optimize welding performance with the PipePro 450 RFC. Both feeders are paired with the Bernard PipeWorx and Centerfire™ consumables. Its combination of tapered tips and nozzles and 60-degree neck enables operators to see the weld puddle more easily on root passes in pipe joints.
