Solid Welding Wire Reduces Rework
ESAB Welding and Cutting Products debuted Purus 42, a solid wire available in diameters from 0.030 to 0.062 in. The wire can reduce post-weld cleaning time and unplanned downtime associated with spatter, reduce or eliminate down-
time for removing silica islands in multi-pass welding, and reduce or eliminate paint-related quality issues. New metallurgy enables Purus, clas- sified as an AWS ER70S-6 EN/ISO G3Si1 wire, to reduce formation of silica islands so that slag self-releases or easily brushes off. The wire is available as a bare wire or with a
copper coating.
Purus reportedly is ideal for high-
volume semiautomatic and robotic applica- tions, with Esab officials noting that one manufacturer of construction equipment reduced arc-ignition errors by 66 percent in multipass applications when using the wire. Pre- viously, according to a company official, excess silica islands prevented positive arc ignition, and when this occurred, the manufacturer needed to shut down the robotic-welding station, spending an average of 3 min. to clean the silica islands. Given the station’s hourly rate of $280, each stop cost $14.
Purus meets all the technical requirements for an S-6 wire, enabling users to change wires without requalification, and offers batch-to-batch consistency due to tight control of element ingredients. The wire also provides good wetting so that the weld puddle flows well and with a smooth tran- sition at the weld toe. And, by creating a good bead profile and surface appearance, it can reduce or eliminate the need for gas-tungsten-arc dressing or grinding to remove stress concentrations.

Automation Module Fits
Small Press Brake Like a Glove
Bystronic introduced a mobile automation module for its Xpert 40 press brake. The result is a compact solution for automated as well as manual bending. Users can process
large lots with the automated bending cell, and also bend small lots or indi- vidual parts manually when necessary. Just plug in and start bend- ing. Setup of the robotic system takes just a few
minutes. Also intro-
duced at FABTECH were two new options for the Xpert 40 (shown): a bending- line laser, which enables part bending without using the
backgauge, ideal for conical parts and others that do not provide a stop position; and an optical
footswitch control to optimize versatility and ergonomics.

Cutting Wheels Prevent Loading When Finishing Aluminum
Weiler Abrasives Group introduced the newest addition to its lineup of Tiger aluminum cutting, grinding and combo wheels. The new offering features a nonloading formula that keeps the wheels from gumming up, allowing operators to get more work done in less time. Further, their extended

wheel life reduces changeovers and lowers cost-of-use to improve productivity and the bottom line.
“Fabricators know aluminum can be challenging to work with because of its low melting temperature and tendency to load and stop cutting,” says Rick Hopkins, Weiler’s senior product manager—metal fabrication. “We designed this new line of cutting and grinding wheels to help address those challenges.”
The new wheels complement the company’s Tiger Alu- minum resin fiber discs, Tiger Ceramic Saber Tooth flap discs, nonwoven products and power brushes.
