 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

Warning
Gas Hook Up
When using the MIG or TIG welding 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 gas-
es for MIG welding are either welding grade CO2 or a Argon/CO2 blend
with 75-80% Argon and 20-25% CO2. For TIG welding pure Argon must
be used.
1. Insure the cylinder is properly secured to the welder, a wall or other
stationary support to prevent it from falling over during setup or oper-
ation. 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 output 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 appropriate gas inlet fitting
on the welder making sure that the hose is not kinked or twisted.

Loading & Feeding Wire—MIG
Note: Always turn power off when wor king inside
the welder enclosure.
Note: It is a good idea to take the contact tip off of
the gun prior to feeding the wire.
8” or 12” Diameter Spool
1. Remove the plastic tensioning cover (1), load
spool with wire coming from under the spool (for
8” spool put spool spacer on first). Replace plastic
tensioning cover (tighten enough so the spool does
not turn freely).
2. Flip down the wire tensioning arm (2) and flip up
the left and right idle arms (5). Make sure the
grove size on the drive roll (5) is in the feeding
position that matches the wire size being used.
3. Feed the wire through the input wire guide (3),
across the left side wire guide roller, through the
center wire guide, over the right side wire guide
roller and in to the output wire guide.
Note: In order to pr event the spool fr om un-
winding; it is important to keep tension on the wire
until after the idle arm and tension arm are back in
place.
4. Flip down the left and right idle arms and flip up
the wire tensioning arm.
5. Turn the welder on, press the Quick Feed Button
to advance the wire quickly through the gun hose.
Note: If feeding problem occur because the wire
is excessively flattened, turn the wing nut on the
spring loaded tension arm (1) counter clockwise to
reduce the pressure. If the drive roll (5) is slipping
while feeding the wire; turn the wing nut clock-
wise to create more tension on the wire.

Adjusting Friction Break
While turning the spool with one hand begin tight-
ening the plastic tensioning cover with the other.
Once you start to feel tension; then turn the cover
an additional 1/4 to 1/2 turn.
The intent is for the friction break to produce just
enough friction to prevent the spool from continu-
ing to turn after the drive motor has stopped.

Maintenance
General Maintenance
Power Supply Compartment
The Hot Max 250WFG does not have any serviceable
parts inside the power supply compartment. Do not
attempt to service parts in the power supply compart-
ment. Doing so will void the warranty. Contact
KDAR Company for instructions if you have prob-
lems that can not be corrected by following the trou-
ble shooting instructions.
If you are working in dusty areas, dirt may get into
the air vents and cause the welder to run hot and trip
the thermal overload protection. If this happens, blow
the dirt out with low pressure air regularly.
Wire Feed Compartment
1. Occasionally dirt will accumulate in the wire feed
compartment. When this happens, simply vacuum
the dirt out of the compartment.
2. Each time the wire spool is changed, inspect the
inside diameter of the wire guide tubes. If neces-
sary, clean the inside of the tube.
3. The motor and gearbox needs no lubrication or
maintenance.
Gun Cable
1. To clean the cable liner, remove the gun cable
assembly from the welder and lay it out straight
on the floor.
2. Take the contact tip off of the gun. Blow low
pressure air through the liner from the gun end of
the liner.
Warning
Electrical Shock Can Kill
Disconnect from the input power source prior to working inside the welder.
Allow only qualified personnel to do maintenance and trouble shooting.
Gun Cable (cont.)
3. Flex the cable over its entire length and blow
air through again. Repeat flexing the cable and
blowing air through until no dirt comes out.
Contact Tip & Nozzle
1. When dirt builds up in the contact tip hole,
wire feeding can be restricted. To clean the tip,
run the appropriate sized tip cleaner through
the tip repeatedly. This should remove any dirt
that has built up on the walls of the contact tip.
KDAR Company tip cleaner number 22034 is
available from selected distributors.
2. Remove splatter from the inside gas nozzle and
the tip frequently.
