When this style is adopted, the client should design the tongs
according the IHS cutting torch tongs sketch map which is provided
by our company. All the plasma IHS, whatever over-water cutting
and under-water cutting, can adopt this IHS style. Please adopt the
approach switch IHS style if you use the high frequency input arc
plasma and under-water cutting.
The tongs sketch map: Please see the appendix
Before IHS, the approach switch is on approaching status. The
cutting torch will rise once the switch is broken away.
Working process: After the height controller receives the arc-on
signal which is sent out from NC system, the cutting torch will fall
down immediately. When the cutting torch gets to the material, the
approach switch will break away from the approaching spot. The
height controller receives this signal, and then controls the cutting
torch to rise to the given Height of IHS (the approach switch will
reposition automatically during the rising). The height controller will
control the plasma to arc on automatically after IHS. This IHS style
is suitable for all plasma IHS.
