The impact-resistant case design protects the wire and drive mechanism from moisture, dust and contamination. with DX Feeders The PipePro 450 RFC power source can be combined with either the PipePro SuitCase™ or PipePro DX Bench Feeders and Bernard PipeWorx™ Guns to offer a total solution for pipe welding applications in the shop or field. ™ PipePro DX Bench Feeder Provides a reliable wire feeder solution for shop applications. The dual-feeder version allows the operator to easily switch from one process/wire for root pass welding to another process/wire for fill and cap welding. IMPROVED WELD PERFORMANCE Regulated Metal Deposition (RMD™ Pro) Precisely controlled short-circuit transfer technology provides welders with an easy to use welding process with excellent puddle control for the root pass. Calm, stable arc/puddle reduces weld training and improves quality. PipePro 450 RFC Provides one versatile power source to produce pipe welds using conventional and advanced processes in shop and field applications. Pro-Pulse™ This method of pulse welding is easier to use than conventional pulse in out-of-position pipe welding applications. This is accomplished through precise control of the arc and puddle even in narrow joints, which provides optimum molten puddle control for out-of-position welding. Precise control of puddle produces excellent side wall fusion on all pipe joint designs. Bernard PipeWorx 250-15 Provides an ergonomic solution to producing root passes on pipe and other medium-duty applications. Designed by welders to reduce fatigue and improve visibility of the puddle on the root pass. Bernard PipeWorx 300-15 or 400-15 Provides a heavy-duty solution to producing root, fill and cap welds on pipe. Power source is warranted for 3 years, parts and labor. Miller Electric Mfg. Co.

The PipePro 450 Welding System provides one versatile solution for pipe welding in a package for both field and shop fabrication. Standard welding processes include new patented RMD™ Pro and Pro-Pulse™, conventional MIG, GMAW-P, FCAW, Stick, TIG, and Air Carbon Arc Cutting. The RMD Pro and Pro-Pulse welding processes are optimized for steel and stainless steel pipe. Programs are provided for the most common gases, wire types and wire diameters used in the pipe welding industry. Contact Miller for more information on less common materials and gas combinations. PipePro™ 450 RFC Features Auto-Line™ Allows for any input voltage hook-up (190 – 630 V, 50/60 Hz) with no manual linking. Compensates for voltage spikes and drops within the entire range. 1/4-turn connectors Allow for faster installation of system and reduces thread stripping. Multiprocess Select from Stick, TIG, MIG, GMAW-P, RMD Pro, Pro-Pulse MIG, FCAW and Air Carbon Arc. Wind Tunnel Technology Circulates air over components that require cooling, not over electronic circuitry, which reduces contaminants and improves reliability. Field or Shop Can be used with either a SuitCase feeder for field construction, or a single or dual bench-style feeder for shop fabrication. Fan-On-Demand™ Cooling system operates only when needed. Reduces amount of airborne contaminants pulled through the machine. Easy to operate Simple front panel layout makes it easy to select programs. ™ Specifications (Subject to change without notice.)

Wirefeed Connector Welding Process Capabilities RMD™ (Regulated Metal Deposition) Pro RMD Ball Transfer A precisely controlled short-circuit metal transfer that provides a calm, stable arc and weld puddle. This provides less chance of cold lap or lack of fusion, less spatter and a higher quality root pass on pipe. The stability of the weld process lessens the puddle manipulation required by the welder and is more tolerant to hi-lo conditions, reducing training requirements. Weld bead profiles are thicker than conventional root pass welds which can eliminate the need for a hot pass, improving weld productivity. In some stainless steel applications, it may be possible to eliminate the backing (purge) gas to further improve productivity and reduce welding costs. Current Wave Form <- Wet -> Pinch Clear Blink Ball Background Pre-short Ideally suited to root pass welding Tolerant to hi-lo fit-up conditions Thicker root passes can eliminate hot pass Consistent side wall fusion More tolerant of tip to work distance Eliminate backing gas on some stainless steel applications Less weld spatter Less welder training time Pro-Pulse ™ This method of pulse welding provides a shorter arc length, narrower arc cone and less heat input than with traditional spray pulse transfer. Since the process is synergic, arc wandering and variations in tip-to-work distances are virtually eliminated. This provides easier puddle control for both in-position and out-of position welding, reducing welder training time. The process also improves fusion and fill at the toe of the weld, permitting higher travel speeds and higher deposition. This process coupled with RMD Pro for root pass welding permits welding procedures with one wire and one gas to eliminate process switch-over time. Ideally suited to fill and cap pass welding Shorter arc lengths and narrow arc cone for out-of-position welding Less heat input reduces interpass cooling time and improves weld cycle time Easier puddle control than conventional spray pulse More tolerant of tip to work variation Enables one-wire with one-gas weld procedures Improve fusion and fill at toe of weld PipePro™ Welding Programs RMD Pro programs designed for root pass welding on deep groove welds in all positions.

Also aids in feeding difficult wires. PipePro DX Dual Feeder Dual tension control adds flexibility for the operator to fine-tune the pressure on the wire independently when feeding a variety of wires. Trigger Receptacle Oriented in a downward position to reduce potential damage. Trigger Hold Reduces operator fatigue by allowing the operator to make long welds without having to hold the trigger continuously. Posifeed Wire Drive Assembly • Quick-change drive rolls • Quick-release, calibrated drive-roll pressure adjustment arm allows drive roll change without losing spring preload setting • Floating positive drive systems provide trouble-free feeding on a variety of wires Stored Programs Allows the operator to select weld programs from the feeder (8 on a single feeder or 4 on each of the feeders of the dual) to improve cycle time from root to fill and cap. Remote Trigger Select Allows operator to change programs (weld process and stored parameters) without returning to the feeder. Dual Schedule Allows the operator to switch between two sets of parameters to provide consistent penetration and improve pipe weld quality in fixed position. Weld Sequence Control Provides gas preflow and postflow for welding of stainless steel and high alloy pipe materials. Improves start and stop conditions by providing run-in, crater and burn-back controls. Range Locks Allows weld parameters to be adjusted within a specified range of set-point to ensure welding procedures are maintained on the shop floor. ™ Specifications (Subject to change without notice.)

The PipeWorx 300-15 or 400-15 are recommended for fill and cap pass welding with Flux Cored arc or pulsed MIG welding processes. In roll welding applications where one gas and one wire are used to make the weld, the PipeWorx 400 can be used to deposit the root pass. (A smaller nozzle diameter should be considered for improved puddle visibility and should be used for stainless steel root pass welding without purge gas.) Specifications Versatility Can be used for MIG (solid and metal cored wires), pulsed MIG, and Flux Cored (shielded and self-shielded wires). Ergonomics Compact, lightweight gun with high-amperage capability reduces operator fatigue. improving productivity. Visibility The combination of tapered tips and nozzles and 60˚ neck provides excellent visibility on root passes in pipe joints. Centerfire™ Tip Provides “drop-in” tip with no threads providing quick changeover. No tools are required. (Subject to change without notice.)
