摘要： A plasma arc torch is provided that includes a tip having an improved life. The tip defines a first set of fluid passageways, a second set of fluid passageways and an internal cavity in fluid communication with the first and second fluid passageways. The internal cavity includes a base portion disposed proximate and surrounding a central orifice of the tip. A first set of fluid passageways allow for entry of a cooling fluid into the tip and a second set of fluid passageways allow for exit of the cooling fluid from the tip.

摘要： A method of starting a multi-gas plasma arc torch for cutting a workpiece is provided that includes directing a pre-flow gas within the plasma arc torch and switching the pre-flow gas to a plasma gas before a pilot arc is transferred to the workpiece. The plasma gas is supplied initially at a first gas pressure when the pre-flow gas is switched to the plasma gas. The gas pressure is switched to a second gas pressure that is different than the first gas pressure after the pilot arc is transferred. The method provides a smooth transition from the pre-flow gas to the plasma gas and reduces the time delay in replacing the pre-flow gas with the plasma gas in the plasma arc torch, thereby improving cut or marking quality.

摘要： A machine tool or die that is fabricated from thermally spray-formed steel is repaired on the factory floor by first cleaning the area to be repaired to removed all dirt and impurities. Next the surface is prepared by means of preheating the surface with propane torches at a rate not exceeding 50° Centigrade per hour to boil off the moisture in the tool. The weldment is formed by the TIG welding process and then finished by conventional machining, grinding and polishing.
