___________________________________________________________________________________________________ 4 Adjustment of welding head The welding head allows studs to be automatically fed through a stud feed tube directly into the stud chuck. The plunger in combination with a selection of distance sleeves serves as a limit stop for welding studs of different lengths.
___________________________________________________________________________________________________ Adjustment of stud chuck Choose the appropriate conversion kit for the respective stud diameter. Insert weld stud into the opening of the stud chuck (ignition tip or stud flange must point in the direction of the collet chucks of the stud chuck). ...
___________________________________________________________________________________________________ Push stud feed tube (item 2, chapter 4.2) through the support retainer (item 4, chapter 4.2). Ensure correct positioning while doing so. Adjusting the depth of immersion MORTAL DANGER The stud welder must be switched off before adjusting the depth of immersion. ...
___________________________________________________________________________________________________ Connect SK-5AP welding head to power supply unit. Connect power-supply unit to a 230 V socket. Switch on power-supply unit of digital display. Roughly set final limit stop by means of the adjusting screw (item 7, chapter 4.3.1). The welding head (item 13, chapter 4.3.1) should not touch the workpiece retainer or table top when moving downwards.
___________________________________________________________________________________________________ Adjusting the height of lift The height of lift is the distance the stud is lifted from the workpiece during the welding process and which is required to ignite the arc. The height of lift always depends on the respective stud dimension and welding task. To set the lift, switch on the stud welder.
___________________________________________________________________________________________________ Adjusting the speed of the lifting cylinder If the welding head touches the workpiece with too much force when moving down, the ignition tip, especially in case of aluminium studs, may become deformed, thus negatively impairing the welding result. Two choker valves are mounted to the air connections of the lifting cylinder (item 11, chapter 4.3.1) to control the speed when the welding head is moving vertically.
___________________________________________________________________________________________________ 5 Start-up Installation of welding head into mounting device The welding head with pneumatic slide is usually supplied in operative condition together with a mounting device or a CNC bench welding machine. Connection of welding head to stud welder ...
Move welding head into welding position by supplying the air cylinder with compressed air. With SOYER bench welding machines this can be done by operating the two-hand release or with SOYER CNC bench welding machines by calling the welding program.
6 Quality control (stud welding) General Provided that the SOYER stud welding system is properly used and the materials are appropriately selected, the strength of the welded joint (weld zone) will always be stronger than that of the stud or base material. The following tests are carried out in general practice: ...
___________________________________________________________________________________________________ Test execution 6.3.1 Visual inspection The visual inspection serves as a rough check for major defects. The uniformity of the weld is assessed. Good welded joint. Optimum setting. Collar spattered for about 1 – 1.5 mm around the flange. Stud flange is completely welded.
___________________________________________________________________________________________________ 6.3.2 Bend test The bend test is a simple work test which serves to roughly check the setting values selected. The welding zone is subjected to undefined tension, pressure and bending. A minimum of 3 studs are welded and bent by 30° using a tube slipped over the stud.
Note Numerous special accessories are available for optimally testing stud welded joints. BP-1 SOYER Bend Testing Device for non-destructive stud testing to support quality assurance procedures DMS-1 SOYER Torque Wrench for non-destructive stud testing to support quality assurance procedures For further information, please contact our parent company or the customer service responsible for your area or...
Please note: A special wrench is needed to perform work. CAUTION Disconnect the mains cable from the mains supply before replacing any components. Electric ® and electronic components may only be replaced by the SOYER customer service or by trained specialised personnel. DANGER TO HEALTH Before starting maintenance works, disconnect the shielding gas supply and compressed-air supply from the connections of the stud welding equipment.
