Figure 4-1. ESP-101 Controls

CAUTION

Position the ESP-101 at least 10 feet (3 meters) from the cutting area.

Sparks and hot slag from the cutting operation can damage the

unit.

4.1 ESP-101 Controls

A. Power Switch (ON-OFF)/(I-O). Turn knob clockwise to "ON" ("I") position for normal operation. Turn knob counter-

clockwise to switch "OFF" ("O").

Note that with the switch in the "ON" ("I") position, power is provided to the main transformer and the low voltage

control circuitry. In the "OFF" ("O") position, the unit is shut down; however, power is still present in the unit. To remove

power from the power source, power must be disconnected at the line disconnect switch or the fuse box.

B. Pressure Regulator. Regulates cut gas pressure. Rotate clockwise to increase and counterclockwise to decrease. Pressure

reading is indicated on the lower display screen. Pressure unit of measure is indicated on the upper display screen.

DANGER

Note:

The unit is shipped from the factory with the regulator adjusted to deliver 80 psig (5.5 bar) to the torch from a 95 psig

(6.5 bar) supply. If supply pressure to the machine is greater than 95 psig (6.5 bar) up to the maximum recommended

150 psig (10.3 bar), rotate pressure regulator knob counterclockwise to reduce the pressure delivered to the torch

back to 80 psig (5.5 bar). Follow GAS TEST instructions, see D.2.

Note:

With or without Junction Box installed: When using 4.5' (1.4 m) or 17' (5.2 m) torch assemblies, plasma gas settings

should be reduced 5 - 10 psi (.35 - .69 bar) for optimum performance.
