INSTRUCTION MANUAL FOR PLASMA ARC CUTTING DEVICE
Read this manual carefully before using the machine.
Failure to respect the rules described herein shall ex-
empt the manufacturer from any liability.
The machine has been designed, built and protected (per
standards: IEC 974.1 - EN 60974.1) for the functions described
below. Any other use not explicitly included shall be considered
FORBIDDEN.
The machine must be used in sufficiently ventilated rooms, in the
absence of dust and moisture; in any case, where there is no risk
of fire, explosion, or flooding.
The machine must be started, used and serviced by qualified
personnel. Always follow current safety regulations.
The manufacturer shall not be held responsible for any damage
caused by incorrect use of the machine.
INTRODUCTION
This device must be used exclusively for cutting on any
electrically conductive material (metals and alloys).
PLASMA cutting takes place due to the high temperature
generated by a concentrated electric arc, and thus highly
dangerous situations may arise; it is therefore essential to pay
the utmost attention to the chapter entitled SAFETY PRECAU-
TIONS.
The symbols next to certain paragraphs indicate points requiring
extra attention, practical advice or simple information.
This manual must be kept carefully in a place familiar to
everyone involved in using the machine. It must be consulted
whenever doubts arise and be kept for the entire life-span of the
machine; it will also be used for ordering replacement parts.

1 INSTALLATION

1.1 UNPACKING AND ASSEMBLY
Open the upper portion of the packing. Remove the torch,
supplied separate from the machine. Remove the two eyebolts
from the accessories box and screw them onto the machine
using the two Belleville washers. Use a lift to remove the device
from the packing. Mount the two casters on the front and the two
wheels on the back. Mount the handle, following the drawing in
Fig. 1.This handle shall not be used to lift the machine.
Place the device in an adequately ventilated room, taking care
10
not to block the air circulation through the cooling slots.
1.2 TORCH ASSEMBLY
This system is suitable for use only with CEBORA P70 and
P150 torches, both manual and automatic.
After inserting the torch fitting Q into the guard G, insert the torch
into the fixed connector P, screwing the ring-nut of the fitting Q
all the way down to avoid any air leaks, which could damage or
interfere with smooth operation of the torch.
Do not dent the terminal pin or bend the pegs in the torch fitting
Q. A dented pin cannot be connected, while a bent peg
does not allow the fitting Q to be fitted firmly into the fixed
connector P, preventing the machine from operating.
Screw the guard G onto the panel.
