For utilization and geographic location, in its October Offshore Rig Locator, Offshore Data Services shows 290 jackups working, out chipper of a total worldwide fleet of 387 rigs, for 75% utilization, down 5% from last shredder year''s 79%. The U.S. Gulf of Mexico had 108 jackups tractor working, of a total 139 available, chipper for shredder 78% utilization. The second most active area was the Persian Gulf, with 32 of its 46 rigs active. Asia accounted for 66 rigs--in India, 22 units were all active; SE Asia tractor and chipper had 18 of its 26 shredder rigs working, and the Far East area had 16 of 18 jackups contracted. West Africa had only 12 of its 26 rigs working. Other active areas were: tractor Mediterranean/Black Sea, 12; the Caspian, chipper 7; Mexico, shredder 6; Venezuela, 6; the Red Sea, 7; and Brazil, 5.

Under-hood generators typically tractor are rated from 5kw chipper to 10kw. The generator is located in the engine compartment and belt-driven from the engine. Power can be used while shredder driving or stationary. The only other component to the belt-driven generator is a control box, about the size of a computer tower that needs tractor to be located in a compartment.The PTO generator can be installed on a two-wheel drive light-duty rig if it''s equipped with a PTO opening on the transmission. This typically is offered as a chipper manufacturer option, but it needs to be added when shredder and tractor the vehicle is ordered. A PTO generator can''t be used on a four-wheel drive unit because chipper of the location shredder of the transfer case in relation to the PTO opening on the transmission.

GTAW torches come air-cooled and water-cooled. Their heads tractor align in-line with the body or at 90, 120, or 135 degrees to it. Nozzles, specified by inside diameters, run 1/4 to 5/8 in. Vendors offer special designs: longer to give chipper improved accessibility to the weld joint, or wider to extend shielding gas coverage.Saw guns come in three-types-side, concentric, shredder and deep-groove flux delivery.In oxyfuel welding (ofw), heat comes from burning gases, rather tractor than arcs, Torches hold separate tubes for fuel gas and oxygen, blended in a mixer assembly. A torch assembly comprises a handle (aluminum, stainless steel, or brass); a mixing chamber; and a brass welding tip or cutting head. Light-duty torches weld sheer metal to 3/16, in. thick; medium, to 1/2 in.; heavy, 1/2 in. and up.
