1-1. Symbol Usage
Means Warning! Watch Out! There are possible hazards
with this procedure! The possible hazards are shown in
the adjoining symbols.
Marks a special safety message.
Means “Note”; not safety related.
This group of symbols means Warning! Watch Out! possible
ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary actions
to avoid the hazards.
1-2. Arc Welding Hazards
The symbols shown below are used throughout this manual to
call attention to and identify possible hazards. When you see
the symbol, watch out, and follow the related instructions to
avoid the hazard. The safety information given below is only
a summary of the more complete safety information found in
the Safety Standards listed in Section 1-4. Read and follow all
Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this unit.
During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomatic or automatic wire welding, the
wire, wire reel, drive roll housing, and all metal parts touching the
welding wire are electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on
unit.
Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
Always verify the supply ground – check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
When making input connections, attach proper grounding conduc-
tor first – double-check connections.
Frequently inspect input power cord for damage or bare wiring –
replace cord immediately if damaged – bare wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or poorly spliced cables.
Do not drape cables over your body.
If earth grounding of the workpiece is required, ground it directly
with a separate cable.
Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
Do not connect more than one electrode or work cable to any
single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of
input power on inverters.
Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
FUMES AND GASES can be hazardous.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use exhaust at the arc to remove
welding fumes and gases.
If ventilation is poor, use an approved air-supplied respirator.
Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breathing air is safe.
Do not weld in locations near degreasing, cleaning, or spraying op-
erations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and if necessary, while wearing an
air-supplied respirator. The coatings and any metals containing
these elements can give off toxic fumes if welded.
XR™ Python® Owner's Manual Page i
Page 6
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
ARC RAYS can burn eyes and skin.
Wear a welding helmet fitted with a proper shade of filter to protect
your face and eyes when welding or watching (see ANSI Z49.1
and Z87.1 listed in Safety Standards).
Wear approved safety glasses with side shields under your
helmet.
Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
Wear protective clothing made from durable, flame-resistant mate-
rial (leather and wool) and foot protection.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
WELDING can cause fire or explosion.
Protect yourself and others from flying sparks and hot metal.
Do not weld where flying sparks can strike flammable material.
Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
Do not use welder to thaw frozen pipes.
Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
FLYING METAL can injure eyes.
Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use
approved air-supplied respirator.
HOT PARTS can cause severe burns.
Do not touch hot parts bare handed.
Allow cooling period before working on gun or
torch.
MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away.
Wearers should consult their doctor before
going near arc welding, gouging, or spot
welding operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
Wear approved ear protection if noise level is
high.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding
process, be sure to treat them carefully.
CYLINDERS can explode if damaged.
Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, slag, open flames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
Never drape a welding torch over a gas cylinder.
Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder – explosion will result.
Use only correct shielding gas cylinders, regulators, hoses, and fit-
tings designed for the specific application; maintain them and
associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.

1-5. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic 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 doctor,
then following the above procedures is recommended.

Gun weight (less leads)....................................................... 2.5 lbs. (1.13 Kg)
Support Equipment Required
• C.V. or C.C. power source of sufcient capacity for your needs.
• Regulated gas supply and hoses.
• Properly sized power leads from power source to wire feeder and ground.
Gun Lead Connections
Power Cable
A #2 AWG power cable is used on the XR™ Python®. The gun end of
the cable has a tting crimped to the copper cable strands. This tting is
then threaded into the gun body. The cabinet end of the power cable is
incorporated into the Power Pin connector.
Conduit
The XR™ Python® comes standard with a poly-lined conduit, for feeding
aluminum wire. The longer tting with a shallow groove is used on the gun
end. A set screw located on top of the gun handle secures the conduit in
place. The cabinet end of the conduit is incorporated into the Power Pin
connector.
Gas Hose
The gas hose is pushed over a barbed tting on the gun body and secured
with a plastic tie wrap. The cabinet end of the gas hose is incorporated into
the Power Pin connector.
Electric Cable
A multi-conductor control cable is used on the XR™ Python®. The gun end
of the cable is secured with a cable clamp and the wires are connected to the
potentiometer, the micro switch, the motor and the gun body mechanically.
Slack is left in the electric cable as it exits the back of the gun to prevent
cable and/or wire breakage. The cabinet end of the control cable uses a 10Pin, "X" clocked Amphenol connector.
Section 4 Operation
General
The Python® maintains a constant, steady, uniform wire feed speed,
regardless of curved or looped wire conduit. The constant push exerted
by the slave motor in the cabinet, combined with the pull of the gun motor,
XR™ Python® Owner's Manual - Page 1
Page 14
causes the wire to literally oat friction-free through the wire conduit. The
24VDC gun motor is controlled by a three and three-quarter (3 3/4) turn
potentiometer in the gun handle.
Controls and Settings
Potentiometer
The laterally-positioned potentiometer is located in the lower end of the
handle, providing up to 875 ipm (22.2 mpm) with 3 3/4 turns.
Micro Switch
The micro switch assembly consists of a normally open micro switch and
solder-attached leads.
Trigger Sensitivity
The amount of trigger level travel can be
shortened for a quicker or more responsive
action.
A more sensitive trigger lever is produced by
reducing the gap between the trigger lever
and the micro switch lever. By turning-in the
trigger sensitivity adjustment screw, it closed
the gap between the trigger lever and the
micro switch lever.
This will enable the operator to increase the
sensitivity of the trigger lever.
Sensitivity Adjustment
With the wire feeder turned on (with or
without welding wire loaded), turn the screw
in until the micro-switch is activated. Once
activated, the gun and wire feeder motors
will begin feeding wire. Retract the screw
accordingly until the system is deactivated
and adjusted to the operators' liking.
Drive Roll and Idler Rolls
The Python® comes standard with a knurled drive roll and a grooved idler
roll, which will handle both steel and aluminum wire with diameters from
.030-1/16 inch. Optional insulated V-groove drive rolls are also available for
aluminum wire if desired (see optional kits).
Drive roll tension is accomplished with a unique spring-loaded pressure
screw. The Python® comes from the factory with the pressure adjustment
screw preset.
Drive Roll Installation/Removal
Note: Neither of the handles needs to be
removed to access the drive or idler rolls.
1. Pull the cam lever away from the idler
roll. This will relieve the pressure against
the drive roll (as shown in Figure 1).
NO ADJUSTMENT REQUIRED FOR ANY WIRE SIZE AND ALLOY

Section 5 Options and Accessories
Insulated Drive Roll Kits
Used to prevent preheating of the wire which may soften it and clog the liner.
This picking up of current at the drive rolls rather than at the contact tip is
usually not a problem unless using too large of a contact tip or excessively
oxidized aluminum wire.

Barrel Removal and Installation
To remove the barrel assembly, loosen the patented EZ Lock™ taper lock nut
until it is clear of the threads. Pull barrel out of the gun body.
To replace a barrel assembly, push the barrel assembly into the gun body
until it stops. To assure proper seating of the barrel, open the drive/idler roll
door in the top of the handle. The rear face of the barrel should now be ush
with the gun body. Take care not to damage the o-rings when inserting into
the body. Tighten taper lock nut assembly rmly so that barrel cannot rotate
while welding.
Barrel Rotation
To rotate a barrel assembly, loosen the patented EZ Lock™ taper lock nut
assembly no more than 1 turn. Rotate barrel to the position of your choice
and re-tighten taper lock nut assembly rmly so that the barrel cannot rotate.

Section 6 Maintenance
Periodic Maintenance
Your XR™ Python® is designed to provide years of reliable service.
Maintenance of the gun will normally consist of a general cleaning of the wire
guide system, including barrels, drive rolls, and conduits at regular intervals.
Remove spatter build-up from inside of nozzles with a hardwood stick.
The only parts that are subject to normal wear are the conduit, contact tips,
nozzles, barrel liners, wire guides, drive and idler rolls. A supply of these
parts should be maintained on hand.
The number of units in operation and the importance of minimal down time
will determine to what extent spare parts should be stocked on hand. See
the recommended spare parts list for the most commonly replaced parts.
If repairs do become necessary, qualied shop maintenance personnel can
easily replace any part.
Maintenance Tools
Tool Part Number
Drive Roll Removal Tool 215676
Reference the table below for suggested Maintenance Tools used with the
XR™ Python® welding gun.
Testing The Gun
Reference the "X" clocked Amphenol diagram
on the XR™ Python® electrical diagram
for information about pin-outs and locations.
Motor Check
Remove the connector from the cabinet.
Using the Amphenol connector, check the resistance across pins “C” and
“B” (motor leads). The resistance across the motor should be between 5
- 10 ohms as the potentiometer is turned.
If an open circuit or short exist, check the motor leads and motor
independently.
Testing the Gun Potentiometer
Using the amphenol connector, check the resistance across pin “F”
(wiper) and pin “E”. The resistance should vary from 0 - 5K ohms as the
potentiometer is turned.
XR™ Python® Owner's Manual - Page 5
Page 18
Check the resistance across pin “F” (wiper) and pin “H”. The resistance
should vary from 5K - 0 ohms as the potentiometer is turned.
Testing the Micro Switch
Using the amphenol connector, check for continuity across pins “D” and “G”
when the trigger is pressed.

manufacture of said parts.
Section 8 Troubleshooting Guide
To aid in troubleshooting problems with your welding equipment, it is best
to understand the basic theory of operation for this Push-Pull System. The
slave motor in the feeder runs at a fast, constant speed, but has very low
torque. It is always trying to feed more wire than the gun motor wants,
and when the motor gets all it wants, it slows the slave motor, preventing
a bird’s nest. Because of the low torque produced by the slave motor, a
brake system is used to prevent wire overrun rather than tension. The drag
adjustment in the feeder is used simply to keep the wire slightly taut, so it will
not pull off the spool while feeding wire.
The high torque 24VDC gun motor is controlled by a solid state speed
control located in the feeder, and a pot located in the gun. The gun motor,
potentiometer, and micro switch are connected to the cabinet/control box via
a control cable and Amphenol connector. If this cable becomes damaged, a
variety of symptoms can occur, depending on which wire(s) break. To test,
check each wire for continuity and shorts.
Remember, the micro switch in the gun activates both the slave motor and
gun motor circuits in the cabinet. Therefore, if the slave motor and brake
solenoid operate, but the gun does not, look more toward the gun motor’s 24
V circuits, speed control, control cable, or the gun motor. If nothing operates,
look more toward the slave motor’s input, micro switch leads, or micro switch.
