1.03 Applications
The industry has enthusiastically adopted air carbon-arc gouging and found many
uses for the process in metal fabrication and casting finishing, chemical and petroleum
technology, construction, mining, general repair, and maintenance.
Victor ® Arcair ® Torches and Electrodes are used throughout the world, anywhere
metal is gouged, grooved, severed, or removed from a surface.
The air carbon-arc process is flexible, efficient, and cost effective on practically any
metal: carbon steel, stainless steel and other ferrous alloys; gray, malleable and ductile
iron; aluminum; nickel; copper alloys and other nonferrous metals.
1.04 The "BEST" Just Got Better...
Victor ® Arcair ® is changing the game when it comes to the power and air connection
design on their K-Series torch cable assemblies.
Since the invention of the air carbon-arc process in 1949, the torch and cable have
always used a molded rubber "boot" to provide electrical protection for the power
connection by preventing arcing against a grounded work surface. This boot design
incorporates a large open rectangular end that allows the power cable and air hose
space to connect to the torch cable. However, the boot can expose the power
connection to the grounded work surface if it is not properly installed and kept in place
over the connection.
Now, the improved boot design encapsulates the power/air connection, eliminating
the chance of accidental arcing. It can accept one 4/0 welding cable from the power
supply and one ¾” diameter air hose assembly that provides current and compressed
air.
This new boot design is molded from a hard nylon reinforced fiber material that can
withstand the abuse of everyday use in a fabrication shop.
