EXCELLENT FOR PIPELINES, CONSTRUCTION AND MAINTENANCE

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.

The Classic® 300 MP multi-process engine-driven welder responds to the numerous challenges that are a fact of life in pipe welding operations. For example, the welder features Temperature Stabilization™, enabling you to “set it and forget it” by eliminating any need for adjustments based on ambient conditions or warm-up period.

With a standard built-in CV output contactor, this engine-driven welder eliminates the need for a separate wire feeder module and the downtime associated with installing it. Additionally, the OCV Boost function can be used to aid starting and low amperage welding. And, a standard on-board block heater is ready to pre-heat the engine for use in cold environments.

Some variables will always be beyond your control, but quality, efficiency and performance should always be within reach – no matter how long the pipeline or how challenging the job. Eliminate the unpredictable with an engine-driven welder that gives you consistent power and maximum control.

 

DC From the Start

The Classic 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 cut-outs and costly repairs.

 

5 Step 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 Classic 300 MP is equipped with a 5 step current control that used in conjunction with a fine tuning control allows for precise setting of Amps, Volts, and Slope for 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.

Day after day, year after year and decade after decade, pure DC generator machines like the Classic 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.

That’s what you call a true workhorse.
