SR6_1/00
1-1. Symbol Usage
Means Warning! Watch Out! There are possible hazards with this
procedure! The possible hazards are shown in the adjoining symbols.
This group of symbols means Warning! Watch Out! Possible ELECTRIC SHOCK and HOT PARTS hazards.
Consult symbols and related instructions below for necessary actions to avoid the hazards.
1-2. GTAW Torch Hazards
GTAW WELDING can be hazardous.
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN
AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR.
In welding, as in most jobs, exposure to certain hazards occurs. Welding is safe when precautions are taken. The
safety information given below is only a summary of the more complete safety information found in the welding
power source Owner’s Manual. Read and follow all safety precautions.
HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY
QUALIFIED PEOPLE.
Marks a special safety message.
Means NOTE; not safety related.
ENGLISH
ELECTRIC SHOCK can kill.
1. Always wear dry insulating gloves.
2. Insulate yourself from work and ground.
3. Do not touch live electrode or electrical parts.
4. Repair or replace worn, damaged, or cracked
torch or cable insulation.
5. Turn off welding power source before changing
tungsten electrode or torch parts.
6. Keep all covers and handle securely in place.
ARC RAYS can burn eyes and skin.
1. Wear welding helmet with correct shade of filter.
2. Wear correct eye and body protection.
3. Cover exposed skin.
FUMES AND GASES can be hazardous
to your health.
1. Keep your head out of the fumes.
2. Ventilate area, or use breathing device.
3. Read Material Safety Data Sheets (MSDSs) and
manufacturer’s instructions for material used.
BUILD UP OF GAS can injure or
kill
1. Shut of f shielding gas supply when not in
use.
2. Always ventilate confined spaces or use
approved air-supplied respirator.
WELDING can cause fire or explosion.
1. Do not weld near flammable material.
2. Do not weld on closed containers.
3. Watch for fire; keep extinguisher nearby.
HOT SURFACES can burn skin.
1. Allow torch to cool before touching.
2. Do not touch hot metal.
3. Protect hot metal from contact by others.
NOISE can damage hearing; SOME
APPLICATIONS, SUCH AS PULSING,
are noisy.
1. Check for noise level limits exceeding those
specified by OSHA.
2. Use approved ear plugs or ear muffs if noise level
is high.
3. Warn others nearby about noise hazard.

EMF INFORMATION

Considerations About Welding And The Effects Of Low Frequency
Electric And Ma g netic Fields
Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from operator as practical.
5. Connect work clamp to workpiece as close to the weld as
possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doc
tor, then following the above procedures is recommended.

5-2. Preparing Tungsten Electrode For Welding
Grinding the tungsten electrode produces dust and flying sparks which can cause injury and start fires. Use
local exhaust (forced ventilation) at the grinder or wear an approved respirator. Read MSDS for safety information. Consider using tungsten containing ceria, lanthana, or yttria instead of thoria. Grinding dust from
thoriated electrodes contains low-level radioactive material. Properly dispose of grinder dust in an environmentally safe way. Wear proper face, hand, and body protection. Keep flammables away.

Select and prepare tungsten according to Sections 5-1 and 5-2.
Guidelines:
The inside diameter of the gas cup should be at least three times the
tungsten diameter to provide adequate shielding gas coverage. (For
example, i f tungsten is 1/16 in diameter, gas cup should be a minimum of
3/16 in diameter.
Tungsten extension is the distance the tungsten extends out gas cup of
torch.
The tungsten extension should be no greater than the inside diameter of
the gas cup.
Arc length is the distance from the tungsten to the workpiece.

MILLER PRODUCTS ARE INTENDED FOR PURCHASE AND
USE BY COMMERCIAL/INDUSTRIAL USERS AND

In the event of a warranty claim covered by this warranty, the

Miller. Therefore no compensation or reimbursement for
transportation costs of any kind will be allowed.
TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE FOR
DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR

ANY OTHER LEGAL THEORY.
ANY EXPRESS WARRANTY NOT PROVIDED HEREIN AND
ANY IMPLIED WARRANTY, GUARANTY OR

OF LAW, CUSTOM OF TRADE OR COURSE OF DEALING,
INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR
PURPOSE, WITH RESPECT TO ANY AND ALL EQUIPMENT
FURNISHED BY MILLER IS EXCLUDED AND DISCLAIMED
BY MILLER.
Some states in the U.S.A. do not allow limitations of how long an
implied warranty lasts, or the exclusion of incidental, indirect,
special or consequential damages, so the above limitation or
exclusion may not apply to you. This warranty provides specific
legal rights, and other rights may be available, but may vary
from state to state.
In Canada, legislation in some provinces provides for certain
additional warranties or remedies other than as stated herein,
and to the extent that they may not be waived, the limitations
and exclusions set out above may not apply. This Limited
Warranty provides specific legal rights, and other rights may be
available, but may vary from province to province.
