* Safety is key when operating a skid steer with any attachment. A Machinery Talker says, "The very best attachment is a good operator."AnBoThis hydraulic grapple rake sports 3,000-PSI welded cylinders and steel teeth that curve to allow material to roll in front of the rake. Several models are available, ranging from 3'' to 9'' wide. Driven by the skid steer''s hydraulics, this standard high-flow chipper offers an infinite number of speeds. 5"-capacity model continuously chips limbs up to 3" in diameter; 8", high-flow model tackles 5" limbs. Detach, park, and fill the Dumping Hopper, then reattach and drive to the dump site, where it tips forward and empties itself. Model 10 has a heaped capacity of 29.7 cubic feet, and Model 25 can haul 87.9 cubic feet of material.

For special applications, manufacturers offer metal-cored wires for GMAW. These are composite electrodes comprised of a metal sheath with a powder-metal core. They are often confused with flux-cored wires, which form a slag that completely covers the weld bead face; metal-cored wires produce very little slag. A major advantage of metal-cored wires is the ability to manufacture specialized alloy compositions not easily available or producible in solid wire fore1. Modifying the composition of the powder-alloy core allows the wire manufacturer to customize wire formulations to metallurgical, compositional, or physical properties per customer demand. Horizontal-fillet welds made with metal-cored GMAW can deposit weld metal at rates up to 20 percent higher than with solid wire. Alloying elements, such as silicon, in the powder-metal core improve sidewall wetting and reduce weld-bead convexity by reducing surface tension of the molten weld pool. For this reason, flat and horizontal welds deposited with metal-cored wires have better appearance than weld metal deposited with flux cored and solid wires. Compared to solid wires, metal-cored wires also result in higher current density, for increased penetration; a wider operating window with respect to welding-process variables: better sidewall melting; and less lack of fusion.
