OPERATION
B-3
After choosing the proper welding wire
for your application, load the aluminum
wire, connect the gun and cable to the
welding machine. (See Installation
Section).
WELDING PROCEDURES
1. Read and understand Arc Welding Safety
Precautions located throughout this manual
and the Welding Machine’s Instruction Manual.
Also for helpful hints in welding see (LTW1) the
Learn to Weld manual which is supplied with
the welding machine.
2. Obtain and use the proper personal protective
equipment for welding. Connect the WORK
(welding ground) cable(-) to piece(s) being
welded. Make sure gas hose from cylinder’s
regulator is connected to welder’s gas INLET.
Open cylinder’s gas valve.
3. Connect input power to the machine.
4. Turn the machine’s power switch to "on". Set
wire speed and voltage tap settings to tables
which are provided in the beginning of this
section.
5. Flip toggle selector switch inside of machine to
"MAGNUM
®
Pro 100SG" position. Press and
hold trigger for about 5 seconds to purge hose.
Be sure the Gas flow rate is set to 20 to 50
SCFH thru the spool gun.
SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Only qualified personnel
should perform this main-
tenance.
• Turn the input power OFF at the dis-
connect switch or fuse box before
working on this equipment.
• Do not touch electrically hot parts.

ROUTINE AND PERIODIC
MAINTENANCE
RECOMMENDED TOOLS
• #2 Phillips screw-driver
• Slotted screw-driver
• 5/16 inch nut driver
• Torque Wrench
• Adjustable-jaw pliers
• 7/16 inch open-end wrench (gas diffuser)
• 9/16 inch open-end wrench (gun tube nut)
• Welding pliers (optional)
• Wire cutter
• Wire stripper
• Needle nose pliers
• Terminal crimping tool
• Flashlight
• Hand-held electrical meter *
• 3.0 mm metric allen wrench (drive roll
screw)
• Tape measure or 6-inch scale
• Tachometer (optional)
*Note: Two meters are used for simultaneously
measuring drive motor’s voltage and current.
CLEANING AND INSPECTIONS
• Vacuum out any aluminum shavings that may
have accumulated inside of the gun. ( See
Correcting Wire Shaving Issues in this section).
• Wipe off dust and debris.
• Check that the gun tube and its lock nut are
properly tightened to the cable connector.
• Replace any warning or product identification
decals that have become illegible.
6. Cut off the aluminum wire so that it extends
about 1/4 inches from the contact tip.
7. CTWD (Contact Tip to Work Distance): Position
the gun so that the contact tip is nominally 3/8
inches from the joint and tilted with a push
angle toward it. The aluminum wire should not
contact the workpiece. (See figure B.1)
FIGURE B.1
8. Protect the eyes and pull the trigger to begin
welding.
9. Adjust the hand travel speed of the gun to
achieve a proper weld. The emerging wire
should stay within the molten puddle and not
overrun it. This speed also should not be so
slow that either the workpiece excessively
melts, or the weld bead becomes excessively
large.
10. Release the trigger to stop welding.

GAS DIFFUSER REPLACEMENT
This part may need to be replaced if it
has accumulated excessive spatter and
cannot be cleaned:
1. Remove gas nozzle and contact tip.
2. Carefully grasp gun tube with pliers
to prevent accidentally loosening gun
tube. Gas diffuser has right-hand
threads. Loosen gas diffuser with
wrench. (See Figure D.1)
FIGURE D.1
3. Install gas diffuser and thread into
place in gun tube. Tighten diffuser to
41 to 47 in.-lbs. with Torque Wrench.
