2. Safety Symbol Definitions

Means Warning! Watch Out! There are possible hazards

with this procedure! The possible hazards are shown in

the adjoining symbols.

Have only trained and qualified persons install, operate,

or service this unit. Call your distributor if you do not un-

derstand the directions. For WELDING SAFETY and

EMF information, read wire feeder and welding power

source manuals.

Beware of electric shock from wiring. Beware of moving parts.

Beware of electric shock from the cutting torch or wiring.

Touching the cutting torch while in contact with the work

or ground can cause electric shock. Always wear dry

gloves. Keep all panels and covers closed.

Hot flux and parts can cause burns. Welding makes flux

and parts very hot – let them cool before touching.

Cutting sparks can cause fire or explosion. Move flam-

mables away. Do not cut on closed tanks or barrels –

they can explode. Clean tanks or barrels properly.

Arc rays can burn eyes and skin – wear face protection

(helmet or face shield) with correct shade of filter, and

cover exposed skin with nonflammable clothing.

Allow cooling period. Reduce current or reduce duty cycle

before starting to cut again. Follow rated duty cycle.

Grinding causes flying pieces of metal and sparks. Wear

a face shield.

Wear safety glasses with side shields. Recycle or dispose of used flux in an environmentally

safe way.

3. Flux Hopper Installation And Loading

ST-801 966

1 Flux Hopper

2 Mounting Bracket

The flux hopper should be mounted

on the fixture above the submerged

arc gun. The flux hopper must be

above the gun to ensure a gravity

flow of flux. A four foot (1.2 m) hose

is supplied to connect the flux hop-

per to the gun. Cut hose off to de-

sired length, and discard unused

portion.

3 Top Cover

4 Latches

To open the top cover, release

latches and lift off cover. A lift-out

screen is supplied to screen slag

and large particles from used flux.

Ensure that the flux inlet control on

the gun is closed while loading. If a

flux recovery system is installed on

the hopper, open cover of recovery

box to load or add flux.

4. Flux Recovery System Installation

ST-801 967 / ST-801 968

1 Flux Recovery System

This system installs directly on the

top of the FH-30B flux hopper and is

secured in place by hopper cover

latches. To install the unit, proceed

as follows:

Remove cover from hopper.

Place recovery system on hopper

as shown in figure (flux screen must

remain in hopper).

Secure system to hopper by fully

closing latches.

Install pickup hose on air valve.

Install standoff bracket on insulated

portion of gun body. If gun body is

not insulated, install provided insu-

lator onto gun body before installing

standoff bracket.

Y Do not install standoff brack-

et on uninsulated gun body.

Do not install metal nozzle

on standoff bracket.

Y Always install provided insu-

lator around uninsulated

gun body, and connect hose

to standoff bracket.

Install desired nozzle in hose, and

secure hose to standoff bracket

with nozzle at desired position.

. It may be necessary to shape

(grind or cut) the nozzle to more

closely match the specific weld

bead or joint. The closer the

nozzle is to the welding sur-

face, the better the flux recov-

ery will be.

Y Hot flying particles can in-

jure personnel, start fires,

and damage equipment.

Shape nozzle only on grind-

er with proper guards in a

safe location wearing proper

face, hand, and body protec-

tion.

Install filter bag on exhaust pipe.

Connect air supply to air valve (see

figure). The valve will accept a stan-

dard air hose connector.

. Although moisture in air lines is

normally evaporated by hot flux

during recycling, it is recom-

mended that an in-line filter be

added and bled daily to avoid

possible moisture problems.

. Consult the flux manufacturer

for the proper ratio of new to re-

cycled flux.

Open cover to

add flux; close

during operation

Connect air

supply to valve

Install nozzle

in hose

Secure nozzle/hose at

desired position by

installing on supplied

gun standoff bracket

Air Supply

on/off lever

Remove cover from

hopper and install recovery

system on hopper

Install bag on

exhaust pipe

Install hose

on valve
