1 SAFETY
Users of ESAB equipment have the ultimate responsibility for ensuring that anyone who
works on or near the equipment observes all the relevant safety precautions. Safety
precautions must meet the requirements that apply to this type of equipment. The following
recommendations should be observed in addition to the standard regulations that apply to
the workplace.
All work must be carried out by trained personnel well-acquainted with the operation of the
equipment. Incorrect operation of the equipment may lead to hazardous situations which can
result in injury to the operator and damage to the equipment.
1. Anyone who uses the equipment must be familiar with:
○ its operation
○ location of emergency stops
○ its function
○ relevant safety precautions
○ welding and cutting
2. The operator must ensure that:
○ no unauthorised person is stationed within the working area of the equipment
when it is started up.
○ no-one is unprotected when the arc is struck
3. The workplace must:
○ be suitable for the purpose
○ be free from drafts
4. Personal safety equipment:
○ Always wear recommended personal safety equipment, such as safety glasses,
flame-proof clothing, safety gloves.
○ Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which
could become trapped or cause burns.
5. General precautions:
○ Make sure the return cable is connected securely.
○ Work on high voltage equipment may only be carried out by a qualified
electrician.
○ Appropriate fire extinquishing equipment must be clearly marked and close at
hand.
○ Lubrication and maintenance must not be carried out on the equipment during
operation.

WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting. Ask for your employer's safety practices which should be
based on manufacturers' hazard data.
ELECTRIC SHOCK - Can kill
• Install and earth the unit in accordance with applicable standards
• Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing
• Insulate yourself from earth and the workpiece
• Ensure your working stance is safe
FUMES AND GASES - Can be dangerous to health
• Keep your head out of the fumes
• Use ventilation, extraction at the arc, or both, to take fumes and gases away
from your breathing zone and the general area
ARC RAYS - Can injure eyes and burn skin
• Protect your eyes and body. Use the correct welding screen and filter lens and
wear protective clothing
• Protect bystanders with suitable screens or curtains
FIRE HAZARD
• Sparks (spatter) can cause fire. Make sure therefore that there are no
inflammable materials nearby
NOISE - Excessive noise can damage hearing
• Protect your ears. Use earmuffs or other hearing protection.
• Warn bystanders of the risk
MALFUNCTION - Call for expert assistance in the event of malfunction.
Read and understand the instruction manual before installing or operating.
PROTECT YOURSELF AND OTHERS!
CAUTION!
Read and understand the instruction manual before
installing or operating.
ESAB can provide you with all necessary welding protection and accessories.

2 INTRODUCTION
2.1 General
The TPC 75 pressurised flux tank is used to supply flux to welding equipment that requires a
large amount of flux, or to compact welding equipment designed for use in restricted spaces.
The pressurised flux tank can be used as a free--standing floor unit or be mounted on a
stand or column and boom using a support bracket. It is part of ESAB’s range of flux
equipment which includes flux vacuum systems and other flux handling equipment.
2.2 Equipment
The TPC 75 pressurised flux tank comprises the items presented in the graphic.
A. Flux sieve with removable mesh G. Stand
B. Safety valve which opens if pressure in
tank exceeds 0.6 MPa
H. Connection for flux hose 1” × 25 m
C. Gauge for monitoring pressure in tank I. Support bracket (optional accessory)
D. Connection for compressed air hose
3/8”
J. Valve which closes if air pressure
exceeds 0.15MPa, even if tank is full and
there is flux remaining in the funnel
E. Water trap with valve in base for
draining condensed water from
compressed air
K. Attachment for level sensor (optional
accessory)
F. Pressurised flux tank L. Lifting points for use during installation

TPC 75:
• Conforms to pressure vessel standards and is approved by Statens
Anläggningsprovning in Sweden and TÜV in Germany.
• Equipped with automatic shut--off valve which closes if air pressure exceeds 0.15 MPa.
• Equipped with:
○ Tap for air supply.
○ Tap for removal of air from the tank.
○ Filter regulator with automatic water trap.
○ Safety valve which opens if air pressure is too high.
○ Flux hose (25 m) for connection to flux container.

4 INSTALLATION AND OPERATION
0443 408 101 -9- © ESAB AB 2021
4 INSTALLATION AND OPERATION
1. See dimensions in the "DIMENSIONS" appendix.
2. The flux tank has two lifting holes (L) (M12)in the top flange for use during installation.
If the flux tank is used on mobile welding equipment it must be fixed securely using
the support bracket (I). Permanent installation is also recommended in stationary
applications.
3. Connect the 1” flux hose (H) and compressed air hose (D) to the pressure regulator
using double hose clamps to ensure secure connection.
NOTE!
Do not release compressed air from an empty flux tank. Remnants of flux may
be blasted out of the flux outlet. The same applies if the flux hose comes loose.
Escaping air can cause dust in the air. Minimise exposure to dust by regular
cleaning.
4. Pour the flux into the funnel, which is fitted with a sieve (A). Recommended maximum
capacity is about 10 cm below the level of the connection flange.
NOTE!
The self-sealing valve (J) closes at a pressure of 0.15 MPa even if the tank is
full and there is flux in the funnel.
5. Open the compressed air valve (B).
6. Adjust to a suitable working pressure of 0.2–0.4 MPa using the pressure regulator,
and read the pressure at the gauge (C).
NOTE!
Pressure should be no higher than necessary to obtain satisfactory operation
with the welding equipment in use.

5 MAINTENANCE
0443 408 101 - 10 - © ESAB AB 2021
5 MAINTENANCE
• Empty all flux from the flux tank when not being used for welding. Flux absorbs
moisture from the air.
• When emptying the tank use the minimum air pressure necessary to avoid blasting flux
out of the tank.
• Keep the work area free from dust and flux by cleaning regularly.
• Replace the flux hose when it becomes worn.
• Check the water trap daily to monitor compressed air quality. If water is present it may
be necessary to install a dehumidifier.
NOTE!
Pressure vessels used for flux distrubution should be inspected for renewed approval
every 5th year.
