Filed:

Apr 24, 1987

Appl. No.:

7/042058

Inventors:

James A. Conley - Meadville PA

International Classification:

B23K 900

US Classification:

21912139

Abstract:

A plasma cutting system comprising a frame, a work support on said frame and a tubular torch support. Gantry apparatus for moving the tubular torch support laterally and longitudinally relative to work on the work support. The torch support is moved a fixed distance from the work and has a ski cup on the lower end of the tubular work support to move over the work. The tube is urged downward by a spring so that as the ski cup runs over the work, the tube is lifted and held at a constant distance from the work. A torch support bearing in the lower end of the torch tube freely receives the torch in the tube.

Appl. No.:

6/713045

Inventors:

James A. Conley - Meadville PA

International Classification:

B23K 1500

US Classification:

219121PC

Abstract:

The plasma cutting system of the invention includes a constant height plasma arc cutter, a rolling table and a plasma cutter carrying gantry driven from opposite sides. The rolling table is rolled from a loading position where metal sheets are positioned thereon to a cutting position beneath the plasma arc cutter. The plasma arc cutter is held at a constant height above the rolling table. Each metal sheet loaded onto the rolling table is supported on adjustable pins. The entire cutting area is enclosed and vented. The plasma cutter and the rolling table are supported by the cutting system support. A cutter housing supports a transparent curtain, and the transparent curtain encloses the plasma arc cutter. A gantry is supported by the cutter housing, and the gantry supports the plasma cutter. The rolling table includes a table frame, adjustable pins and table wheels.

Abstract:

A system and method for cutting insulation and metal using a plasma arc is provided. The system includes a plasma arc cutter for cutting sheets of insulation and metal. The plasma arc cutter has a torch adapted to constantly arc. The sheets of insulation and metal are positioned below the torch. The method of cutting insulation and metal uses the plasma arc cutter system to cut sheets of insulation and metal. In accordance with a preferred embodiment of the method of the invention insulation and metal are cut without vertically moving the torch of the plasma arc cutter system. A rolling table of a plasma cutting system is loaded with a sheet of insulation. The table is rolled to move the sheet of insulation into cutting position below the torch. The sheet of insulation is cut and then removed by rolling table out from under the torch, loading a sheet of metal onto the table and rolling it under the torch. The tip of the torch has an electrical ground.
