STAYER WELDING PLASMA Serie Manual De Instrucciones página 23

Introduction
The present product is an equipment for cutting metal manually
by plasma produced by an electric arc and pressurized air.
The equipment applies high-frequency energy transfer by
advanced inverter technology for maximum operation quality
and minimum weight. All equipments have components of
industrial category, components sized with overvoltage and
overcurrent resistance reserve and double-shielded EMI filters,
and microprocessor smart controls. Solid construction under
IEC/EN 60974-1 and the RoHS Directive. Maximum quality
components, 600V switches, 450V/1400V capacitors and cutting
edge HF ferrite transformers.
Compared to traditional technology based on transformers
operating at 50/60Hz public mains frequency, the STAYER
WELDING Inverter technology has a higher power density
per weight unit, is more economical and has the possibility of
accurate, instantaneous and automatic control of all welding
parameters.
As a result, you will produce a better cut with greater facility
with an equipment which is less consuming and lower weight
compared to traditional equivalent equipments.
The whole product range is controlled by microprocessor for
maximum safety, performance and easiness of use (smart
equipments).
The whole product range is adapted for use with stabilized
motor-generators.

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
injury. Possible hazards are shown in the attached
symbols or explained in the text.

avoided, will lead to death or serious injury. Possible
hazards are explained in the text.
2.2. Arc-welding hazards.
Only qualified persons may install, operate,
maintain 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 insulating 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 current in humid areas, when your
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, on metal
structures such as floors, grates or scaffolds; when you are in
a tight position such as seated, kneeling, lying down or when
there is a high risk of having unavoidable or accidental contact
with the workpiece or ground.
• Disconnect power input or stop the motor before installing or
servicing this equipment.
