When it comes to pipeline construction and maintenance, you deal with more unpredictable variables than you’d care to count. Adverse weather, natural terrain and regulatory requirements are just a few. Given the natural and man-made uncertainties often associated with your business, you need equipment you can count on to maximize quality and efficiency, minimize repair time and control costs.
DC from the Start
The SAE-300 MP is powered by a hand-built pure DC generator from the only welding manufacturer providing this proven technology to the market. The all-copper windings and flat DC output ensure a smooth, stable arc that enhances arc control, helping operators keep defects to a minimum to avoid cutouts and costly repairs.
Dual Current Control
No two pipe joints are the same – hi-lo fit-up, out-of-round pipe and gap variations can challenge any bead hand to lay in a defect-free weld subject to 100% x-ray inspection. Getting those results requires tremendous control over the arc. The SAE-300 MP is equipped with dual continuous current control – use the coarse control to set a digging, penetrating arc for root beads or a soft, buttery arc for stacking iron on the fill and cap passes. Then you, or your helper using a remote control, can dial in the fine control to adjust heat input, or arc sensitivity, in response to fit-up and orientation of the weld puddle on the pipe.
Built for the Long Shift
Pipelines are all about mileage – and in many cases, a lot of it – so you need an engine-driven welder that will go farther without having to stop for refueling. Our 16 gallon (60.6 L) tank is almost 50% larger than the competitor’s 11 gallon (41.6 L) counterpart, which translates to longer run times, improved efficiency and greater cost savings. The new heavy-duty stainless steel case and rugged wired or wireless remotes add to the durability and utility of these welders.
Day after day, year after year and decade after decade, pure DC generator machines like the SAE-300 MP have been proven to take the abuse of field welding with the lowest maintenance costs and best resale value among diesel-driven welders.
