Arc welding technology to be showcased at FABTECH
Miller Electric Mfg. Co. offers a variety of equipment for arc welding that will be on display at the 2008 FABTECH International & AWS Welding Show.
The PipePro system, suitable for field and shop fabrication, features the company's RMD (Regulated Metal Deposition) process, a precisely controlled short-circuit transfer technology that provides welders with a simplified welding process with good puddle control for the root pass, reports the company. The system also features ProPulse, a pulsed GMAW process with control of the arc and puddle, even in narrow joints.
The ProHeat 35 system induces heat electromagnetically to bring a part to temperature in a fraction of the time of flame or resistance-heating methods, the company states. One or two joints can be uniformly heated for preheat or stress relief with minimal setup and instruction time.
The Millermatic 350/XR combines the Millermatic 350P all-in-one GMAW/pulsed GMAW machine with the XR-Aluma-Pro push-pull gun 4000- and 5000-series aluminum feeding and welding. The 350P includes pulsed GMAW programming and is designed to provide a more forgiving arc and increased consumable life, says the manufacturer.
The Millermatic Passport Plus all-in-one GMAW machine helps provide a good arc on mild and stainless steel. When combined with the new direct-connect Spoolmate 100 Series spool gun, the 45-lb. machine welds 18-ga. through 1/4-in. aluminum. A three-position material selection switch sets optimal arc characteristics for steel, stainless steel, and aluminum.
The company has designed the Maxstar 150 DC SMAW/GTAW machine for mechanical contractors, fabricators, and maintenance personnel who work in the field and require a full-featured power source. The machine weighs 13.7 lbs., has a 5- to 150-amp welding range, features the company's Auto-Line technology for automatic linking to 115 to 230 VAC, and has Line Voltage Compensation (LVC) to keep power output constant regardless of plusmn:10 percent fluctuations in input power.
The Maxstar 200 DC GTAW/SMAW inverter-based power supply features Auto-Line technology, allowing it to accept input power from 115 V to 460 V, single or three phase, 50 or 60 Hz without any manual relinking. This allows the user to plug into any type of primary current and begin welding. The 37-lb. machine has a 1- to 200-amp output and produces code-quality GTAW and SMAW arcs, the company reports.
