Safety Precautions
SECTION 1:
SAFETY PRECAUTIONS
WARNING
SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not properly
installed, used, and maintained. Misuse of this equipment and other unsafe practices
can be hazardous. The operator, supervisor, and helper must read and understand the
following safety warnings and instructions before installing or using any welding or cutting
equipment, and be aware of the dangers of the welding or cutting process. Training
and proper supervision are important for a safe work place. Keep these instructions for
future use. Additional recommended safety and operating information is referenced in
each section.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH
Install and maintain equipment in accordance with the National Electrical Code (NFPA
70) and local codes. Do not service or repair equipment with power on. Do not operate
equipment with protective insulators or covers removed. Service or repair to equipment
must be done by qualifi ed and/or trained personnel only.
Do not contact electrically live parts. Always wear dry welding gloves that are in good condition.
Aluminized, protective clothing can become part of the electrical path. Keep oxygen cylinders, chains,
wires, ropes, cranes, and hoists away from any part of the electrical path. All ground connections must
be checked periodically to determine if they are mechanically strong, and electrically adequate for the
required current. When engaged in AC welding/cutting under wet conditions or where perspiration is a
factor, the use of automatic controls for reducing the no load voltage is recommended to reduce shock
hazards. Accidental contact must be prevented when using open circuit voltage exceeding 80 volts AC,
or 100 volts DC by adequate insulation or other means. When welding is to be suspended for any length
of time, such as during lunch or overnight, all electrode holders and electrodes should be removed from
the electrode holder and the power supply should be turned OFF to prevent accidental contact. Keep
MIG-Guns, electrode holders, TIG torches, Plasma torches, and electrodes away from moisture and
water. See safety and operating references 1, 2, and 8.
SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH
Ventilation must be adequate to remove smoke, fumes, and gases during operation to
protect operators and others in the area. Vapors of chlorinated solvents can form the
toxic gas “Phosgene” when exposed to ultraviolet radiation from an electric arc. All
solvents, degreasers, and potential sources of these vapors must be removed from the
operating area. Use air-supplied respirators if ventilation is not adequate to remove all
fumes and gases. Oxygen supports, and vigorously accelerates fi re and should never be used for
ventilation. See safety and operating references 1, 2, 3, and 4.

SET-UP AND SAFE OPERATING PROCEDURES
89210002Safety Precautions
ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN
Welding and cutting processes produce extreme localized heat and strong ultraviolet
rays. Never attempt to weld/cut without a federally compliant welding helmet with the
proper lens. A number 12 to 14 shade fi lter lens provides the best protection against
arc radiation. When in a confi ned area, prevent the refl ected arc rays from entering
around the helmet. Approved shielding curtains and appropriate goggles should be used
to provide protection to others in the surrounding area. Skin should be protected from arc rays, heat,
and molten metal. Always wear protective gloves and clothing. All pockets should be closed and cuffs
sewn shut. Leather aprons, sleeves, leggings, etc. should be worn for out-of-position welding and cutting,
or for heavy operations using large electrodes. Hightop work shoes provide adequate protection from
foot burns. For added protection, use leather spats. Flammable hair preparations should not be used
when welding/cutting. Wear ear plugs to protect ears from sparks. Where work permits, the operator
should be enclosed in an individual booth painted with a low refl ective material such as zinc oxide. See
safety and operating references 1, 2, and 3.
WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS
Combustibles reached by the arc, ame, ying sparks, hot slag, and heated materials
can cause fi re and explosions. Remove combustibles from the work area and/or provide
a fi re watch. Avoid oily or greasy clothing as a spark may ignite them. Have a fi re
extinguisher nearby, and know how to use it. If welding/cutting is to be done on a metal
wall, partition, ceiling, or roof, precautions must be taken to prevent ignition of nearby
combustibles on the other side. Do not weld/cut containers that have held combustibles.
All hollow spaces, cavities, and containers should be vented prior to welding/cutting to permit the escape
of air or gases. Purging with inert gas is recommended. Never use oxygen in a welding torch. Use only
inert gases or inert gas mixes as required by the process. Use of combustible compressed gases can
cause explosions resulting in personal injury or death. Arcing against any compressed gas cylinder can
cause cylinder damage or explosion. See safety and operating references 1, 2, 5, 7, and 8.
NOISE CAN DAMAGE HEARING
Noise from the air carbon-arc process can damage your hearing. Wear protective hearing
devices to ensure protection when noise levels exceed OHSA standards. Adequate hearing
protection devices must be worn by operators and surrounding personnel to ensure personal
protection against noise. See safety and operating references 1, 2, and 6.
WARNING
This product contains chemicals, including lead, or otherwise produces chemicals
known to the State of California to cause cancer, birth defects and other reproductive
harm. Wash hands after handling.

3.04 WIRE FEED SPEED CALIBRATION
NOTE
The Thermal Arc 252i machine must be calibrated to the spool gun before operating to
ensure optimum welding characteristics.
Wire Feed Speed Calibration
Procedure
WARNING
DO NOT TOUCH the electrode wire
while it is being fed through the
system. The electrode wire will be
at welding voltage potential.
Required Equipment/Tools:
Appropriate personal protective gear:
gloves, safety glasses, etc.
• Tape measure
Spool of desired fi ller metal
• Spool Gun
T15 (Torx) driver (supplied)
NOTE
To perform the wire feed speed
calibration procedure the end of
the Spool wire needs to be trimmed
back to the contact tip of the Spool
Gun before and after feeding wire
out for measurement.
NOTE
This calibration procedure does
not affect the calibration of the
wirefeeder inside the 252i. To re-
calibrate the wirefeeder inside the
252i all remote devices must be
disconnected from it.

NOTE
The power supply requires two
values to properly calibrate wire
feed speed. A low feed speed
value and a high feed speed value.
Default speeds span the most
typical jobs. You may choose
alternates that better represent
your work. The closer an upper
or lower speed is to an actual
procedure, the better the accuracy.
NOTE
To perform the wire feed speed
calibration procedure the end of
the Spool wire needs to be trimmed
back to the contact tip of the Spool
Gun before and after feeding wire
out for measurement.
