Description Of The Equipment; Explanation Of Regulatory Markings; Safety Instructions; Symbols Used - STAYER WELDING TIG AC/DC 190HF PULSED Mode D'emploi

DESCRIPTION OF THE EQUIPMENT

This product is an equipment for manually welding metals by
means of heat generated by an electric arch.
Technologically, the Stayer Welding equipment is an electric
power supply source for high-frequency power transfer managed
by intelligent control logics.
In contrast to traditional technology which is based on
transformers operating at 50 Hz public grid frequency, Stayer
Welding has a larger power density per weight unit, is more
economizing and has the possibility of accurate, instantaneous
and automatic control of all welding parameters.
As a result, you will more easily produce improved welding with
equipments that consume less and have a lower mass than
equivalent traditional equipments based on heavy transformers.
All Stayer Welding equipments of the TIG series are capable of
shielded electrode welding and tungsten electrode torch welding
with inert gas protection.

2.- Safety instructions

READ THE INSTRUCTIONS.
• Read the User Manual completely and understand it before
using or giving service to the unit.
• Only use genuine manufacturer's parts.

2.1.- Symbols used

DANGER! - Indicates a dangerous situation which,
when not avoided, will lead to death or serious in-
jury. Possible hazards are shown in the attached
symbols or explained in the text.
Indicates a dangerous situation which, when not

2.2.- Arc-welding hazards
Only qualified persons may install, operate, main-
tain and repair this machine.
During its operation, keep anyone away, especially
children.
ELECTRIC shock may kill you.
Touching live current carrying parts may cause fatal electric
shock or serious burns. The working and electrode circuit is
always electrically live when the machine output is on. The input
circuit and the inner circuits of the machine are also electrically
live when the machine is on. When welding with automatic or
semiautomatic equipment, the wire, the reel, the frame containing
the supply rolls and all metal parts touching the welding wire are
electrically live. Incorrectly-installed or not-earthed equipment is
a very serious danger.
• Do not touch electrically live parts.
• Use dry isolating gloves without openings, and protection on
your body.
• Isolate yourself from the work and from the ground by using
carpets or covers that are sufficiently large to prevent any
physical contact with the work or ground.
• Do not use the AC output in humid areas, when movement is
restricted or when in risk of falling down.
• Use an AC output ONLY when required by the welding process.
• When an AC output is required, use a remote control if there is
one present in the unit.
• Additional safety precautions are required when any of the
following dangerous electric conditions is present in humid
rooms or while you are wearing humid clothing, when working
on metal structures such as floors, grates or scaffolds; when you
are in a tight position such as seated, kneeling, laying down or
