Pipeliners will find that the most efficient welds begin with precise weld preps. E.H. Wachs manufactures precision, portable weld-prep equipment for pipeline maintenance including its Low Clearance Split Frame (LCSF) and Heavy Duty Split Frame (HDSF) for larger diameters pipes. Newly available for the LCSF is a Deep Counterboring Module, ideal for matching dissimilar pipeline wall schedules, for example where mainline thinner wall pipe joins heavy wall pipe used under roadbeds.
The LCSF is a part of a complete in-situ machining system, designed for cutting, beveling, facing and counterboring carbon and high yield pipe from 2- to 48-in. outer dimater (DN50-1200). Where a typical counterbore might be 1 in. (25.4 mm), the Deep Counterbore can go as deep as 6 in. (152.4 mm), using an Acme type feed screw for fast material removal, making these connections quick and easy. The LCSFis available in pneumatic, hydraulic and electric
Wachs HDSF series of split frames are built for larger pipelines ranging from 12- to 84-in. outer diameter (DN 300-2100) and offers similar capabilities as the LCSF and features rugged, all steel construction.

The new Big Blue 800 Duo Air Pak and Big Blue 800 Duo Pro diesel-engine welder/generators from Miller deliver more power, flexibility, improved weld control and dual operation capabilities. Users will get estimated fuel savings of 34 percent with the dual-operator machines, when compared to two single-operator units. The revamped Big Blue machines offer multi-operator flexibility, perfect for construction jobsites with limited space.
A 33 percent increase in rated power output results in 27,000 watts of generator power and up to 800 amps of weld power for a single operator or 400 amps each for two weld operators. Additional inverters can be plugged into the machines to create a multi-operator work platform, with operators able to weld and get three-phase power at the same time.
The multi-process machines provide improved weld control that increases arc quality and optimizes welding output, resulting in better welds on thicker material. The new engines, compliant with Tier 4 Final emission regulations from the U.S. Environmental Protection Agency, offer reliability, optimized performance, fewer emissions and reduced maintenance.
In addition to fuel savings on a per-arc basis, the dual-operator feature also saves space on the work truck and jobsite, with lower maintenance costs compared to two separate machines.
The Air Pak model adds an Ingersoll Rand screw-type air compressor with 30,000-hour life expectancy for gouging in heavy equipment repairs and maintenance. It also can operate a full range of pneumatic tools, supplying up to 60 cfm of air at 100 psi with a 100 percent duty cycle.
