Starting-up In this chapter you learn what to observe during setting-up and starting-up of the power unit. 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.
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.
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 rmly clockwise. The connection is not secured against...
Ground Connection Plug the ground cable in the connector of the power unit. Press in the plug and twist rmly clockwise. The connection is not secured against working itself loose! Check the plug connections regularly to ensure that they are properly locked.
Shielding Gas Connection Observe the standards (see appendix) when handling the shielding gas bottles. Connect the gas hose of the shielding gas bottle to the gas inlet of the power unit. Connect the gas hose of the welding gun to the gas outlet. Set the ow meter of the shielding gas bottle to 8 - 16 liters/min.

THREAT TO LIFE by toxic vapors and airborne particles Toxic vapors and airborne particles may occur during stud welding operations, especially with surface treated materials. Ensure that a fume extraction is available that the room is adequately ventilated according to accident prevention regulations. If possible, do not weld in rooms which are lower than 3 meters.

stud welding unit are prohibited and result in complete cancellation of any guarantee and liability claims against HBS. In case of any accidents whatsoever, advise a physician, your supervisor, and the o cial bodies immediately.
(see appendix). Drawn-Arc Stud Welding The HBS stud welding unit operates by process of ‘arc stud welding with drawn-arc ignition’ according to the current standards (see appendix). The standards assign this method of joining pin-shaped elements with plane workpieces to the so called ‘Arc Pressure Welding’...
Page 27
– At the beginning of the welding process, the welding element (stud) in the welding gun is lifted clear o the workpiece by a lifting device (solenoid). An initial switched current triggers a pilot arc of a low current power (see position 2). Then the main arc ignites between the face area of the welding element and the workpiece.
5.2.1 Drawn-Arc stud Welding with Ceramic Ferrule Drawn-arc stud welding with ceramic ferrule is used with welding elements of 3 to 25 mm diameter (preferably above 12 mm diameter) and with welding times of 50 to 2000 ms. It is generally suitable for all welding positions. When stud welding with ceramic ferrule, the welding position is PA (vertical).
5.2.2 Drawn-Arc Stud Welding with Shielding Gas Drawn-arc stud welding with shielding gas is used with welding elements for a diameter range of 3 to 12 (16) mm and with welding times from 50 to 2000 ms. Principally, it is suitable for all welding positions, however, it is preferably used in vertical position PA.
5.2.3 Short-Cycle Drawn-Arc Stud Welding with Shielding Gas Short-cycle drawn-arc welding with shielding gas is used for welding elements within a diameter range of 3 to 12 mm (nominal diameter without ange) and welding times between 5 and 100 ms. Due to the short welding times, the energy input and the weld pool are so small that also welding elements up to 12 mm diameter can be welded on thin workpieces.
Welding Preparation Read the safety instructions in chapters 1, 3, and 5. Observe the workplace requirements (chapter 3, ”Starting-up"). Check all cables and connections for proper condition. Replace immediately defective cables and cable connections to avoid electrical shocks. Check the chuck for proper seat (see operating manual of according welding gun).
Page 32
Determination of welding time Data given in the following table are only guidelines. They must be verified by trial welds on the actual material according to actual standards and DVS guidelines (see appendix). Before you use another lot of welding elements, carry out some trial welds to verify the parameter setting.
Further notes on – welding elements – prestress at installation (tie load) and torque – material combinations see appendix and operating manual of the according welding gun. Switching on the Power Unit Improper operation of the stud welding unit is LIFE-THREATENING! First...

The digital display shows the adjusted welding time and welding current. There is a luminous indication (LED) to the right of the display: Yellow – lights if the welding gun button is triggered Yellow – lights if there is electrical contact between welding element and workpiece –...
5.6.1 Adjusting the Welding Time Set the welding time (digital display ) with the arrow keys ( longer – shorter) on the display. 5.6.2 Adjusting the Welding Current Set the welding current (digital display ) with the arrow keys ( higher – lower) on the display.
5.6.4 Library Mode In the library mode, you can call up and modify charging voltages, depending on stud diameter (UD/Pins). Simultaneously press both arrow keys of welding time ( shorter , longer), for about one second. The display welding time shows 0-06 (06 means the set welding current and welding time for stud diameter of 6 mm).
Welding Procedure Improper operation of the stud welding unit is LIFE-THREATENING! The stud welding unit must only be operated by qualified personnel (see chapter 1). Observe the safety instructions in chapters 1, 3 and 5. Prepare the stud welding unit, the ground connection, and the workpiece according to the instructions given in the operating manual.
Checking the Quality of the Weld You can check the quality of the weld by means of a visual inspection and a bending test. See also actual standards in the appendix “Arc stud welding of metallic materials“, in section irregularities and corrective actions.
5.8.2 Bending Test You can purchase from HBS a bending device with inserts for various diameters of the welding elements. The bending test serves as an easy work sample and as a check for the selected welding parameters. Bend the welding element with the bending device once by 60°.
Page 40
Bending Test Type of fracture Possible cause Corrective actions Base material buckling - Correct parameters - none Fracture in welding element - Correct parameters - none above weld collar Fracture in the weld metal - Welding energy too low - Increase welding energy Many pores - Plunging speed too low - Increase plunging speed...
5.8.3 Arc Blow Effect A so called arc blow e ect can occur with unproportionally distributed ground connec- tions in relation to the base material mass, varying material distribution, or welding at the edge of a workpiece. This is an undesired de ection of the arc. It causes a single- sided melting of the stud material, increased pore formation, and undercuts in the welding area.

5.10 Welding Elements The stud welding unit must be suitable for welding the welding elements to be used. Observe the instructions in the operating manuals. Welding elements are mainly manufactured with the cold formed process. We recommend the following standard welding elements (see appendix). Use only welding elements of the same lot.
