Dearcustomer,
Thankyouvery muchforpurchasing apowerunit fromHBSBolzenschweiss-
Systeme.
We from HBS wish you always successful working with this stud welding unit.
We ask you to observe the following points:
– Store the operating manual in a way that it can always be accessed by the
operator.
– Letthe operator signbefore startingup that hehas read and completely under-
stoodtheoperatingmanual.
– This operating manual applies only to this stud welding unit.
– Protectthe stud welding unit fromunauthorized use.

relatedstudweldingunit,areproperlyfusedandgrounded.
– Informourcustomerserviceincaseofmalfunction.
– In case of accident, inform a physician and the responsible official body.
THREATTOLIFE!
Persons fitted with a pace maker must not operate the stud
welding machine.
MAGNETICFIELDS!
During stud welding, strong electro-magnetic fields are
generated. Do not weld in the vicinity of the electrical
equipment which could be affected.
Safety instructions are a delicate subject. Anybody who handles a stud welding
unit, whether it is the welding gun or the power unit, should be familiar with them,
becauseimproper use ofstud welding unitscan be dangerous to life.
For your own sake you should know the safety instructions for operating your HBS
stud welding units inside out.
In addition to the protection of your health and the capital value of the enterprise, the
safety instructions are intended to clarify any responsibilities, which arise from
ownershipandoperationoftheequipment.

3 Starting-up
In this chapter you learn what to observe during setting-up and starting-up of the power
unit.
3.1 Requirements of Workplace
Vapors and airborne particles may occur during stud welding
operations. Especially with surface treated materials, toxic
vapors may be produced.
Ensure that a fume extraction is available and that the room is adequately
ventilated according to accident prevention regulations.
If possible, do not weld in rooms which are lower than 3 meters.
Special regulations apply for confined rooms, according to accident prevention
regulations of the official bodies (see appendix).
Weld only in adequate distance from combustible articles or liquids.
Before you start welding, remove any combustible articles or liquids in vicinity of
the workplace.
Make sure that a fire extinguisher is within reach.
Never weld in rooms exposed to risk of explosion.
Do not set-up the product in the vicinity of any apparatus or equipment which is
sensitive to welding spatter.
Do not set-up the product in the vicinity of any apparatus or equipment which is
sensitive to magnetic fields.
Set-up the power unit:
– on a stable, clean, and level surface
– so that no-one is influenced or injured by welding spatter
– so that all cables and primary lines are protected from being damaged
– so that nobody will trip or fall over the cables or connection lines.
Ensure that air is able to circulate freely through the housing.
If heat is built-up inside the housing caused by bad air circulati-
on, the stud welding unit will be seriously damaged.
3 Starting-up
3.1 Requirements of Workplace

CD2301OrderNo.BA92-12-0231A Issue05.01.10 15
Secure the following safety symbols in the area of welding place:
THREAT TO LIFE to persons fitted with a pace maker
Strong electro-magnetic fields occur in the vicinity of the stud welding
unit during welding. Such fields may affect the proper function of a
pace maker. Thus persons equipped with a pace maker must not
operate the stud welding unit and must not stay in its vicinity during
welding.
During the actual welding process, you must expect red-hot welding
spatters, possibly liquid spatters, a flash, and a loud bang > 90 dB (A).
Alert any colleagues who are occupied in the vicinity of the welder.
Wear your personal protective equipment according to actual
standards (see appendix).
3.2 Connecting the Power Unit to the Primary Power Supply
Compare the primary voltage specified on the type plate with the voltage provided
by your primary power supply. The type plate is located on the backside of the
power unit.
Never connect the welder to a power supply with a voltage
different from the voltage indicated on the type plate.
Check the current consumption specified on the type plate with the fuse rating of
your primary power supply.
Have an electrician check whether the outlet to which you want to connect the
power unit is correctly grounded.
Switch off the power unit.
Insert the primary plug into the checked outlet.

16 CD2301OrderNo.BA92-12-0231A Issue05.01.10
3.3 Connecting the Welding Gun to the Power Unit
Switch off the power unit. In this way, you avoid any risk of
electrical shock.
Plug the welding cable of the welding gun into the socket of the power unit.
Press-in the plug and twist firmly clockwise.
The connection is not secured against working itself loose!
Check the plug connections regularly to ensure that they are
properly locked. In case of loose connection, heat may build up
in the plug and may destroy the entire plug connection.
Plug the control cable in the connector of the power unit.
Twist the retaining nut of the control cable connector clockwise to secure the
connection.
The welding gun cables must not be coiled during welding.
Coiled cables work as a coil and may negatively affect the
welding result. Before welding, lay out the cables lengthwise.
Fix the cables. Strong magnetic fields occur during welding which may cause a
movement of the cables. This may cause a slackness of the connections.

3.4 Ground Connection
Plug the ground cable in the connector of the power unit.
Press in the plug and twist firmly clockwise.
The connection is not secured against working itself loose!
Check the plug connections regularly to ensure that they are
properly locked. In case of loose connection, heat may build up
in the plug and may destroy the entire plug connection.
Remove any rust, paint, or contaminants from the work piece in the areas where
you intend to connect the ground cables.
Connect the ground clamps to the work piece as securely as possible.
Take care to ensure good contact and symmetrical connection.
The welding location must lie directly between the two ground
clamps.
3.5 Change Working Place
Switch off the power unit. In this way, you avoid any risk of
electrical shock.
When you move your workplace, disconnect the welding gun and the ground
cables from the power unit. Proceed in reversed sequence as described in
section 3.2, 3.3 and 3.4.
After changing the workplace, check the welding gun and the ground cables for
possible damage or missing components.

4 Function
In this chapter you learn more about the design of the power unit and how to
use the various setting options.
4.1 Components of the Power Unit
The power unit consists of the following main assemblies:
1 - Transformer 4 - Charging resistor
2 - Rectifier 5 - Welding thyristor
3 - Triac 6 - Capacitor battery
Mains alternating current is converted in the rectifier (2).
Capacitors (6) are continuously adjustable charged by both, the Triac (3) and the
charging resistor (4) and store electrical energy.
The negative pole of the capacitor is connected with the chuck of the welding gun.
The positive pole works as ground connection. It is connected with the work piece by
vice-grips.

5 Stud Welding Procedure
This chapter contains the basics of stud welding, how you must actually proceed, and
what must be observed. You learn to select correct welding parameters and which
welding elements can be used.
5.1 Safety Instructions
Improper operation of the power unit is LIFE-THREATENING!
Threat to life
– by electric shock and arc
– by toxic vapors and airborne particles
– by red-hot metal spatters (fire risk)
– by blow-up of explosive gases and materials
– during welding of hollow parts
– by strong magnetic fields to persons fitted with a pace maker
THREAT TO LIFE by electrical shock and arc
During the actual stud welding process, do not touch the welding
elements, chuck, or retaining nut nor any electrically conductive parts
in their vicinity. These are all electrically life.
Step onto an insulating mat, if you have to weld under the following
conditions:
– in confined rooms with electrically conductive walls
– under confined conditions between or on electrically conductive
parts
– with restricted freedom of movement on electrically conductive
parts
– in wet or hot areas
When operating the stud welding unit, you must not wear any metallic
jewellery incl. wrist watches, especially on hands. Remove any
electrically conductive or electro-magnetically sensitive parts from
your body before you start welding. In this way, you avoid the risk of
damage by electric shock or influence of electromagnetic fields.
