company’s first engine-driven welder from Lincoln Electric to incorporate these tech- nologies.
As a generator, the unit produces clean AC-generator power that allows operators to use power tools, laptops and other per- sonal tech., as well as appliances sensitive to current fluctuations.

Flap Discs With Poly- Cotton Backing, Ceramic Grain Promise Strength
Weldcote Metals has introduced C- Prime and C-Prime Plus ceramic flap discs for grinding. The C-Prime discs feature strong polyester backing for aggressive grinding applications not requiring exces- sive flexibility. The C-Prime Plus discs offer a reported industry first, poly-cotton backing, along with high-quality ceramic grain. Together, these features provides excellent stretch and flexibility, according to company officials, while adding enough strength to maximize the aggressive cutting points of ceramic grain.
The ceramic grains in Weldcote’s line of flap discs contain a grinding aid for cooler running temperatures, which report- edly reduces the risk of discoloration and heat-induced deformations of the final workpiece. These ceramic grains also are self-sharpening, allowing for longer use,
according to company officials. Sizes for the C-Prime flap discs: 4.5 and 7 in.; for the C-Prime Plus discs: 4.5, 5 and 6 in. Weldcote Metals: www.weldcotemetals.com
Long-Lasting Saw Blades for Cutting Ferrous, Nonferrous Metal Alloys
Versatix MP bi-metal band saw blades from L.S. Starrett Co., for cutting ferrous and nonferrous metal alloys, feature triple- tempered, high-speed M-42 cobalt-steel teeth with a steel-alloy steel backing strip. The blade’s patented tooth design dissi- pates stress during cutting, resulting in
less tooth breakage and longer blade life than with other tooth designs, according to company officials. And, the tooth design’s special set minimizes pinching when cutting structurals and bundles.
The saw blades include Starret’s Bi- Metal Unique technology, which joins two strips of high-speed-steel wires to the back- ing steel using solid-state diffusion bonding. Instead of a single wire welded to the outside of a steel backer, explain company officials, this process bonds two strips of high-speed steel to each side of the top edge of the steel backer using intense heat and pressure. This increases the bonding area between the backer and the high-speed steel by more than 170 percent as compared to conventional electron beam or laser welding. This process reportedly creates a stronger, longer-lasting blade. L.S. Starrett Co.: www.starrett.com
