Introduction; Safety Warning; Features; Method Of Operation - Helvi MIRAGE 11 Manual De Instrucciones

INTRODUCTION

Your welding helmet MIRAGE has been designed to
be widely used for various welding applications, MIG,
MAG, TIG, SMAW, CAW (carbon arc welding) and
PAW (plasma arc welding).
It can efficiently protect operator's eyes from injuries
caused by arc, but also can make both hands free and
strike arc accurately. Therefore, the quality of products
and work efficiency may be raised considerably.

SAFETY WARNING

Read and understand all instructions before using.
• Be sure that the dark shade provided by your welding
helmet is suitable for your application.
• This helmet is not suitable for "overhead" welding
application, laser welding or laser cutting applications.
• This welding helmet is designed to protect eyes and
face from sparks, spatters and harmful radiations un-
der normal welding conditions. It will not protect against
severe impact hazards.
• This welding helmet will not protect against explosi-
ve devices or corrosive liquids. Machine guards or eye
splash protection must be used when these hazards
are present.
• Impact resistant, primary eye protection, spectacles
or goggles that meet current ANSI specifications, must
be worn at all times when using this welding helmet.
• Avoid work positions that could expose unprotected
areas of your body to sparks, spatters, direct and/or re-
flected radiations. Use adequate protection if exposure
cannot be avoided.
• Avoid hard blows that may damage the filter.
• Check for light tightness before each use. Before
each use, check that the protection plates are clean.
• Inspect all operating parts before each use for signs
of wear or damage. Any scratched, cracked, or pitted
parts should be replaced immediately.
• Do not make any modifications to either the welding
lens or helmet, other than those specified in this ma-
nual.
• Do not use any replacement parts either than those
specified in this manual. Unauthorized modifications
and replacement parts will void the warranty and expo-
se you to the risk of personal injury.
• Do not immerse this lens in water and keep it away
from dust.
• Do not use solvents on any lens or helmet's com-
ponents.
• The recommended operating temperature is -5°C
e 55°C (23°F-131°F). Do not use this device beyond
these temperature limits.
• Failure to follow these warnings and/or failure to
follow all of the operating instructions could result in
severe personal injury.

FEATURES

Your welding helmet is equipped with a filter DIN11. In
addition, the helmet is also provided with three extra
protection lens made of high polymer materials.
The plate is wear-resistant, thermostable, and has no
dregs-stricking, thus a very long service life.

METHOD OF OPERATION

Assembly

• Assemble the headband to the helmet as shown in
the assembly drawing.

Operation

• Your mask has a fixed DIN 11 protection. Set the
correct welding current according to the welding pro-
cess. Refer to the reference table below.
• Inspect the filter and protective lenses. Remove the
protective film from the protective lenses if they are
new, clean them or replace them if they are dirty or
damaged.

Helmet adjustment (Fig. 1)

• Because the shapes of men's heads vary from per-
son to person, the work position and the observing an-
gle is different and welding helmet needs to be adju-
sted properly.
• Adjust the headband cir-
cumference by pushing and
rotating the knob on the
back of the headband (Fig.
1-1). Turn left to enlarge,
right to tighten. This can be
done while wearing the hel-
met to allow the right tension
to be set to keep the helmet
firmly on the head without it
being too tight.
• Adjust the top strap of
the headband (Fig. 1-2) so
that the helmet gets placed
at the right height on your head.
• Test the fit of the headband, by lifting up and getting
down the helmet a few times while wearing it. If the
headband moves, adjust it again.
• Unscrew the side locking knobs (Fig. 1-3) and free
the locking nuts (Fig. 1-4) on both sides. Slide the hel-
met close to or far from your face to adjust the distance
from your eyes to the filter. It's important yours eyes
are both at the same distance from the lenses.
• Adjust the view angle by moving the adjustment wa-
shers to the desired position.
• Screw the side locking knobs.
