1.0 INTRODUCTION

1.1 EQUIPMENT IDENTIFICATION

The unit's identification number (specification
or part number) model, and serial number
usually appear on a nameplate attached to
the rear panel. Equipment which does not
have a control panel such as gun and cable
assemblies is identified only by the specifica-
tion or part number printed on the shipping
container. Record these numbers for future
reference.
1.2 RECEIPT OF EQUIPMENT
When you receive the equipment, compare
it with the invoice to make sure it is complete
and inspect the equipment for possible dama-
ge due to shipping. All machines dispatched
have been scrupulously checked. However,
should your machine not work properly, con-
sult the section on TROUBLE SHOOTING in
this manual. If the fault persists, consult your
authorized dealer.

2.0 SAFETY WARNING

2.1 GENERAL INSTRUCTIONS

This manual contains all the necessary in-
structions for:
- the installation of the equipment;
- a correct operating procedure;
- an adequate maintenance of the equipment.
Therefore, be sure this manual is carefully
read and understood by the maintenance
and technical operators.
2.2 LOCATION
Welding processes of any kind can be dange-
rous not only to the operator but to any person
situated near the equipment if safety and opera-
ting rules are not strictly observed.
Therefore the owner and the operator must
be aware of all possible risks so that they
may take the necessary safety precautions to
avoid any kind of accident at work.
The main precautions to be observed are:
- Operators should protect their body by
wearing non flam-
mable, close fitting
protective clothing,
without pockets or
turned-up trousers.
Oil or grease should
be carefully removed
from all articles, be-
fore wearing. Ope-
rators should also
wear closed safety
boots with steel toe
caps and with rubber
soles ( Fig. 1).
1. Leather gloves
2. Leather aprons
3. Shoes Cover
4. Security shoes
5. Face mask
- Operators should wear a non- flammable
welding helmet or face shield designed so as
to shield the neck and the face, also on the
sides. The helmet or the face shield should
be fitted with protective glasses adequate to
the welding process and current used. Glass
screens must always be kept clean, and im-
mediately replaced if they are broken or cra-
cked (Fig.2). It is good practice to install a
pane of transparent glass on top of the adiac-
tinic glass, between it and the welding area.
