The pressurized flux delivery system is designed for use
with the semiautomatic and automatic Submerged Arc
Welding (SAW) process and includes two pieces of
equipment: a GA-60CF gun and an AFT-100 flux tank.
An optional FT-1 cart is available to make the system
portable. A wire feeder and constant voltage welding
power source are required to complete the package.
The alpha-numeric designations of the components are
explained as follows:
Gun:
G = Gun
A = Air Cooled
60 = Ampere Rating: 600 Amperes
C = Curved Head Tube
F = Flux (For Flux Use)
The gun is equipped with a trigger lock for operator com-
fort during long welds. The gun trigger is dual purpose –
it controls flux flow and energizes the wire feeder.

SECTION 3 – INSTALLATION
3-1. CART ASSEMBLY AND COMPONENT IN-
STALLATION (Figure 3-1)
To assemble cart and components, proceed as follows:
WARNING: FALLING EQUIPMENT can
cause serious personal injury and equip-
ment damage.
• Use lifting bracket to lift unit only, NOT any
other heavy options, accessories, or devices.
• Use equipment of adequate capacity to lift
the unit.
1. Assemble cart, if applicable, as shown in
Figure 3-1. Be sure all screws, nuts, etc., are
tightened securely.
2. Lifting eyes are provided on the sides of the tank
for handling purposes when the tank is not in-
stalled on a cart (see Figure 3-2).
3. Once the cart is assembled and components in-
stalled, the unit can be lifted with a hoist or over-
head crane using the lifting bracket on cart (see
Figure 3-1).
4. Install flux tank on cart, if applicable, as shown in
Figure 3-1. Tighten all mounting hardware
securely.
5. If applicable, install wire feeder on cart as shown
in Figure 3-1. Tighten screws securely.
3-2. FLUX TANK CONNECTIONS (Figure 3-2 And
Figure 5-1)
To make flux tank connections, proceed as follows:
1. Connect gun flux hose to flux tank fitting, and se-
cure with supplied hose clamp (see Figure 3-2
and Figure 5-1).
2. Obtain appropriate air hose and air hose fitting,
and connect air supply to air hose fitting on flux
tank. This fitting will accept standard air hose
connections. After checking for proper connec-
tion, disconnect air supply.
3-3. GUN/WIRE FEEDER CONNECTIONS
(Figure 3-1)
IMPORTANT: If an optional gun/feeder adapter kit is to
be used, make gun/feeder connections according to the
instructions furnished with the kit.
A. Gun/Feeder Connector Installation
1. Loosen the gun/feeder connector securing knob
on wire feeder drive housing (see wire feeder
Owner’s Manual for location).
IMPORTANT: Install connector so that outlet wire guide
is as close to drive rolls as possible without touching.
2. Insert the gun/feeder connector into opening in
housing (see Figure 3-1).
3. Tighten the gun/feeder connector securing knob.
B. Gun Trigger Connections
1. Locate TRIGGER receptacle on wire feeder
control.
2. Connect gun trigger plug to this receptacle and
secure.
3-4. GUN TRIGGER OPERATION (Figure 3-1)
FLYING FLUX PARTICLES can puncture
eyes and skin: WELDING WIRE can cause
puncture wounds.
• Do not point gun toward any part of the body,
any conductive surface, or other personnel.
• Do not depress gun trigger until ready to be-
gin welding.
The gun trigger has two standard features: a locking de-
vice, and control of both flux flow and wire feeder.
The locking device allows the trigger to be held fully de-
pressed providing operator comfort on long or sustained
welds.
The control of flux flow and wire feeder is obtained by
depressing the trigger. Up to approximately 2/3 depres-
sion will allow partial flux flow only without energizing the
wire feeder. Full depression gives full flux flow and ener-
gizes wire feeder.

ING FLUX PARTICLES can puncture eyes
and skin; WELDING WIRE can cause punc-
ture wounds.
• Do not touch live electrical parts.
• Shut down welding power source and wire
feeder and be sure they cannot be accidental-
ly energized before working on gun
components.
• Close air valve, bleed pressure from tank,
and disconnect air supply.
• Do not point gun toward any part of the body,
any conductive surface, or other personnel.
To change the size of the electrode wire, the only gun
part necessary to change is the contact tube. It may be
necessary to change the wire feeder inlet wire guide –
see wire feeder Owner’s manual for information.
IMPORTANT: Whenever the electrode wire size is
changed, blow out both the monocoil liner and monocoil
casing with compressed air.
1. Remove the nozzle and extension if applicable.
2. Cut off any portion of the electrode wire which ex-
tends beyond the end of the contact tube.
3. Remove the contact tube.
4. Retract remaining electrode wire onto wire spool.
CAUTION: FLYING DIRT AND METAL PAR-
TICLES can injure personnel and damage
equipment.
• Point gun liner only in a safe direction away
from personnel and equipment when clean-
ing with compressed air.
5. Blow out gun casing or liner with compressed air
whenever the wire or liner is removed.
6. Install the appropriate contact tube.
7. Reinstall the nozzle and extension if applicable.
8. Make necessary changes to wire feeder to ac-
commodate new wire size.
9. Thread new size electrode wire (see wire feeder
Owner’s Manual).
10. Reconnect air supply to flux tank.
11. Resume operation.
5-6. REGULATOR MAINTENANCE
The dryer contains silica desiccant to dry excess mois-
ture coming from the filter regulator. Check the color
code located on the metal bowl for the condition of the
desiccant. Replace when necessary.
