TIG torch
Weldcraft recently introduced the Super Cool 18 TIG torch to eliminate overheating on higher amperage, water-cooled applications. Super Cool 18 operates up to 400 amps and features a patented water-cooling chamber, which is designed to limit downtime associated with overheated torch components.
The chamber allows water to flow down, around and up the entire length of the torch head to cool and eliminate collet overheating, softening and twisting.
A stubby collet body adjacent to the water chamber enhances the cooling ability of the torch, while allowing for an optional gas lens to improve gas coverage. The heavy copper components improve cooling efficiency and maximize current capacity.

Nytro Ag Corp and Green Lightning recieved an innovation award at Ag in Motion 2025 for the Green Lightning Nitrogen Machine, which converts atmospheric nitrogen into a plant-usable form.
“The Super Cool 18 saves time and money because the greater cooling capacity reduces weld discontinuities and rework associated with overheating. You can run 400 amps for longer and get the job done quicker,” said Mike Sammons, Weldcraft business development manager.
Super Cool is available with standard WP-18 long or short back caps, uses standard gas lens alumina nozzles, hoses, power cables, and collets with heavy-duty 1/8 -, 5/32- and 3/16-inch models. It accommodates tungsten ranging from 0.020- to 3/16 -inches.

Cummins engines
The next generation of Cummins QSB engines is available for the agricultural market. The engines feature advanced electronics, new sculpted blocks, increased displacement, rear gear drive, high-pressure common-rail fuel system and other features designed to improve durability and reduce noise. These engines meet the EPA Tier 3 emissions requirements and are capable of moving forward to the future Tier 4 requirements.
They are available in both four cylinder and six cylinder. The 6.7-litre QSB is rated at 135-275 hp. The 4.5-litre QSB is rated at 110-170 hp.
Both versions feature an overall 55 percent reduction in sound pressure for quieter operation.
In-cylinder emissions engineering has enabled better performance while meeting regulations without the use of a turbocharger or external hardware.
“Thanks to the rear gear drive and other features, the level of noise and vibration is dramatically reduced,” said Marco Rangel, director of Cummins agricultural engines.
“By closely evaluating tractor duty cycles we were able to precisely shape torque characteristics to achieve the best performance and fuel efficiency across the r.p.m. range.”
The high-pressure common-rail fuel system generates up to 1,600 bar injection pressure that translates to rapid power delivery, reduced noise and better cold starts.
The electronics enable the engine to switch to a higher torque value for dealing with exceptionally high engine loads, such as combine grain tank emptying or when the tractor hits tough plowing ground.
