Plasma Both above water incision and under water incision (Page 14 / 23) XPTHC-100 Plasma Arc-Voltage Controller

Plasma. Both above water incision and under water incision are feasible. Note: You must

satisfy the following requirements when you use multimeter to measure the resistance

quantum of the water.

depth of measure：50mm

space between two pens：10mm

measuring resistance 〉1.5K

The parameter is decided by the examination in the salty water。

6.2、Switch IHS Method of NPN、PNP

All the IHS of Plasma no matter above-water or under-water incision can adopt this IHS

method.

You can check the clamp sketch map in appendix。

Before IHS, Proximity switch is in the situation of approaching, once depart,

the cutting torch will climb immediately。

working process： After the high adjusting machine received the arc signal from CNC

system, the cutting torch descend at once and when it touch the steel plate the Proximity switch

will depart the approaching point then the high adjusting machine receive the signal to make the

cutting torch at a setting certain height. This way is suitable for all the IHS of Plasma.

Proximity switch connect to the Proximity switch through SWITCH-HIS in the high

adjusting machine.

Note: NPN method: Insert the JPT1 slip stitch in the location of NPN, the similar

as PNP insertion for JPT1.
