RER Spotlights: Generators/Welders

Doosan Portable Power

Doosan Portable Power offers four new models in its mobile generator line that are designed to meet Tier 4i emission standards — the G150, G190, G240 and G325 (pictured). The new analog control panel is enhanced with large, brightly lit meters for at-a-glance monitoring. The onboard engine diagnostic display panel now includes the controls and indicators required to operate and maintain the after-treatment regeneration system. A run/idle switch on the control unit ensures reduced engine wear during startup in extreme cold temperatures. All four models feature a Voltage Selector Switch for quick configuration for most common voltages. In addition, all new models have 500-hour service intervals.

Victor Technologies

The Fabricator 211i welder from Victor Technologies is a fully integrated MIG-Stick-TIG inverter welding system that weighs 57.3 pounds and offers the flexibility of using either 115 or 208/230 VAC single-phase primary power, 50 or 60 hertz. It delivers a welding range of 5 to 150 amps on 115 VAC and 5 to 210 amps on 230 VAC. To switch voltages, the user must connect the 115V/20A power adapter “pigtail” supplied with the system.

Miller Electric

Designed for use in construction, maintenance, pipe welding and general fabrication, the Big Blue 450 Duo CST is a dual-operator, diesel engine-driven welding generator that features two CST 280 Stick/TIG inverters and 12,000 watts of continuous three-phase power in a single unit. Powered by Mitsubishi's S4L2 4-cylinder diesel engine, the Big Blue 450 Duo CST provides increased productivity by allowing two welders to work off the same machine with two separate welding outputs. The Tier 4i-compliant machine operates at a low 1,800 rpm, which reduces fuel use and keeps noise levels up to 10dBa quieter than other models.

The new MQ Power Tier 4i generators are equipped with a diesel particulate filter to trap particulate matter, or soot, from the diesel engine exhaust, making them emissions compliant. The self-cleaning design uses a regeneration process, manual or automatic, to burn off accumulated soot once it reaches its factory-set limit. The manual option allows the operator to select the best time to begin regeneration. Visual indicators and diagnostic troubleshooting are provided in the control panel to alert the operator. The control panel is equipped with both analog and digital controls. Analog displays provide quick readings of key performance areas such as oil pressure, water temperature, battery charging, fuel level and engine rpm, while digital displays provide clear readouts of engine and DPF performance.
