DC generator welder for control, stability
- October 18, 2015
Field applications, such as pipeline construction or general construction require reliable, rugged equipment that stands up to rough conditions on the job site. The recently launched SAE-300 MP Pure DC generator welder, the latest engine-driven welder from Lincoln Electric, responds to these challenges, delivering consistent power and maximum control no matter how hot or cold, how long the pipeline or how tough the job, says Lincoln.
This new engine-driven welder features Temperature Stabilization, which enables operators to “set it and forget it,” eliminating any need for adjustments based on ambient conditions or a warm-up period.
Its standard, built-in CV output contactor supports all wire-welding processes and eliminates the need for a separate wire feeder module and the downtime associated with installing it. An OCV Boost function can be used to aid starting and low-amperage welding, while a standard, on-board block heater pre-heats the engine for use in cold environments.
The SAE-300 MP features a 24.7 HP Perkins water-cooled, turbo-charged engine. The machine produces 300 amps DC/32 volts at 60 percent duty cycle and 250 amps DC/30 volts at 100 percent duty cycle. It also provides 3,000 watts of AC generator power. All-copper windings and flat DC output ensure a smooth, stable arc that enhances arc control to help operators keep defects to a minimum, avoiding cutouts and costly repairs.
With the SAE-300 MP’s dual, continuous current control, operators can use the coarse control to set a digging penetrating arc for root beads or a softer arc for stacking iron on the fill and cap passes. Remote control allows operators to dial in the fine control to adjust heat input or arc sensitivity in response to the weld puddle’s fit-up and orientation.
The SAE-300 MP’s larger fuel tank keeps refueling at a minimum. The 16-gal tank is almost 50 per cent larger than the competitor’s 11-gal one, translating into longer run times, improved efficiency and greater cost savings, according to the company.
