All installation, operation, and maintenance procedures are to be
performed only by qualified individuals
ELECTRIC SHOCK CAN KILL.
The input circuits are live and hot when the power is on
Do not touch live electrical parts
Wear dry, hole free insulated work gloves and body protection when operating
Do not touch torch components if in contact with the work piece or ground
Always turn off power before cleaning, checking, or changing parts
Properly ground this piece of equipment per state and federal requirements
Inspect and replace any worn or damaged torch cables or leads
Keep all panels and covers securely in place
Keep away from the torch tip and weld arc when trigger is pressed
Ground the metal or work piece to the ground cable (Earth Clamp)
Never dip the tip into water to cool or attempt to use welder in or under water
This DC equipment holds a lot of power in the off position, before touching, make sure voltage is
near zero on input capacitors before touching any parts.
ARC RAYS CAN BURN SKIN AND EYES
Arc rays when welding produce intense ultraviolet and infrared rays that can burn skin and eyes
Wear face protection, either helmet or shield, when operating. ANSI Z49.1 approved shade #9
recommended for all cutting currents less than 300 amperes. The lens should conform to ANSI
Z87.1 standards for testing.
Wear approved safety glasses with side shields under the face protection
Warn others not to stare at the arc as it can cause damage to the eyes. Provide barriers to protect
other workers in the area from the arc while operating
Wear flame resistant gloves, clothing, and shoes when operating
FUMES AND GASES CAN BE HAZARDOUS
Arc welding produces fumes and gases and breathing these gases is hazardous to your health
Keep your head out of the fumes and do not breath the fumes while welding
Work only in a confined area if it has sufficient ventilation, or while wearing an air supplied
respirator. Fumes from welding deplete the oxygen supply and can be harmful. Always be sure
there is ample breathing air
Read the MSDS sheets and the instructions from manufacturers for metals to be welded, coatings,
and cleaners
Do not use the welder near hydrocarbon vapors coming from degreasing, cleaning, or spraying
operations. The heat and rays can react with solvent vapors to create the gas phosgene, a very toxic
gas and other irritating gases
Do not weld coated metals, such as galvanized, lead, or cadmium plated steel. Before welding, all
plating must be removed. The area must be well ventilated or an air supplied hood must be used.
The coatings and chemicals when burned cause highly irritating and toxic fumes.
Do not weld containers with toxic, flammable, or reactive elements stored in them. They must be
emptied and properly prepared before welding.

WELDING SPARKS CAN CAUSE INJURY, FIRE, OR EXPLOSION
Remove all flammable materials from the welding area
Always have a charged fire extinguisher available in the welding area
When not welding make sure the welding tip is not grounded, this causes a heat build up and
possible fire
Avoid welding near hydraulic lines, fuel lines, electrical cords, air hoses, or welding guns and
cables
Sparks and hot metal fly out from the work area when welding, wear approved safety glasses with
side shields under approved helmets, wear proper body and hand protection, and wear flame
resistant ear plugs to keep sparks from entering the ears
CYLINDERS CAN EXPLODE IF DAMAGED
Gas cylinders contain gas under very high pressure. If damaged they can result in that cylinder ex-
ploding. Gas cylinders are a major part of metalworking and must be treated with care.
Protect gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs
Always keep cylinders in an upright position securely fastened to a fixed support
Valve protection caps should always be in place and hand tight except when the cylinder is in use
Keep all cylinders away from any welding or electrical circuits
Never allow the arc from a welder to contact a cylinder
Never cut any type of pressurized cylinder, an explosion could result
Always turn your face away from the valve when opening the cylinder
Read and follow all instructions on compressed gas cylinders, associated equipment, and CGA pub-
lication P-1 listed in the Safety Standards before using
ELECTRIC AND MAGNETIC FIELDS MAY BE DANGEROUS
Electric current used in arc welding can create Electro-Magnetic Fields (EMF)
Magnetic fields can affect pacemakers and wearers should avoid proximity to EMF. Wearers need
to contact their doctors before operating this type of equipment
Exposure to EMF during operation of this equipment may have other health effects which are not
yet known
Route the work and torch cables together and not around your body
Do not place your body between the torch cable and the ground cable. They both need to be on the
same side of your body when operating
Do not work next to the welding machine
ELECTRICALLY POWERED EQUIPMENT
Disconnect power source or turn off circuit breaker at the power panel before working on any
equipment
Only install equipment using the US National Electrical Code, all local codes, and the man-
ufacturer’s recommendations

HOT PARTS CAN CAUSE SERIOUS BURNS
Do not touch hot parts without wearing protection.
Allow the torch to cool sufficiently before working with parts that could potentially be hot.
NOISE CAN DAMAGE HEARING
Prolonged noise exposure from welding equipment can cause damage if levels of noise exceed the
OSHA standards
Wear approved hearing protectors
Warn other workers nearby of the high noise level and hazard
CALIFORNIA PROPOSITION 65 WARNINGS
Welding or cutting equipment produces fumes or gases which contain chemicals known to the State of California to cause
birth defects, and in some cases, cancer. (California Health and Safety Code Section 25249.5 et seq.)

Warning
Gas Hook Up
When using the GMAW process, a cylinder of shielding gas must be used. Shielding gas cylinders and gas can
be obtained at a local gas supply company or some farm supply stores. The recommended gases for the Hot
Max 175WFG welder is either Welding grade CO2 or a Argon/CO2 blend with 75-80% Argon and 20-25%
CO2 (see Suggested Settings chart on the welder compartment door).
1. Insure the cylinder is properly secured to a wall or other stationary support to prevent it from falling over
during setup or operation. Be sure the cylinder is insulated from the work circuit and ground.
2. Once the cylinder is properly secured,
remove the cylinder cap. Standing to one
side slowly open the cylinder valve for an
instant to blow away any debris that may
have accumulated in the valve outlet.
3. Attach the flow regulator to the cylinder
valve and tighten with a wrench.
4. Attach one end of the gas hose to the out-
put fitting of the regulator and tighten
securely with a wrench.
5. Test to insure the flow regulator is closed
by opening cylinder valve slightly. If the
regulator is not closed turn the black
knob counter clockwise until the flow of
gas has stopped.
6. Connect the other end of the hose to the
gas inlet fitting on the 175WFG welder
making sure that the hose is not kinked or
twisted.

Input Connections
The 175WFG welder has power input cables located on the rear of the unit. A plug for the cord is not included
and must be purchased separately. Follow the directions provided with the plug for terminating the power
cable located on the back of the machine. Make sure the plug you purchase is rated for 250 Volts and 50
Amps minimum.
Gas Hook Up (cont.)
7. Reopen the regulator valve until the flow indicator shows
15 L/min (initial flow setting). The setting may need to be
adjusted by the operator to compensate for welding condi-
tions.
8. Always close the cylinder valve and open the regulator
valve when not in use.
