Safety instructions Safety instructions These operating instructions contain basic instructions which have to be complied with during installation and/or operation. It is therefore absolutely necessary that these operating instructions are read by the operator and responsible specialist staff prior to assembly and initiation. They must always be available at the installation site.
Safety instructions Safety instructions the non-observance of which may endanger the machine and its functions are marked with the terms "CAUTION" or "WARNING". General instructions are marked with the hand symbol. 3.2 Staff qualification and training The staff responsible for operation, maintenance, inspection and assembly must have the respective qualification for carrying out these works.
Safety instructions 3.5 Safety instructions for the operator/user When stud welding, danger may result from • electric current • optical radiation • harmful substances (smoke) • acoustic shock • spraying sparks You are therefore obliged to restrict the dangers to an inevitable degree and to point these dangers out to the operator and other persons involved.
Safety instructions • Wear gauntlet gloves made of leather. • Wear neither rings, watches nor electrically conductive jewellery. • Wear protective goggles to protect your eyes from welding spatters and flashes of light that are generated during the process. • Wear ear protection. Capacitor discharge generates a loud bang. 3.7 Before starting welding ...
Safety instructions 3.9 Working with the stud welder • Comply with all accident prevention regulations which apply to the operation of your stud welder One of the accident prevention regulations applicable for stud welders is VBG15 "Welding , cutting and similar working methods".
• Roll up the cables without buckling them. Our tool and gear wagon GW-1 is the optimum solution for installing SOYER stud welders and for properly storing welding pistols, cables, studs, retrofit kits etc. • Make sure stud welder cannot be used by unauthorized persons.
• Ensure sufficient ventilation of the working room when operating the system. The housing of stud welder BMS-8N corresponds to safety class IP 21. Please observe e.g. that this system of protection is not suitable for being operated or transported in the rain.
Initiation 5.1.1 Operating elements • Mains switch (item 9, chapter 5.1) The mains switch located at the rear side of the stud welder serves to switch the stud welder on and off. • Function key "Arrow up" (item 1, chapter 5.1) The function key "Arrow up"...

DIN 4113, part 2). 6.4 Type and scope of test Provided that the SOYER stud welding system is properly used and the materials are appropriately selected, the strength of the welding joint (welding zone) will always be stronger than that of the stud or base material. The follow- ing tests are carried out in general practice: •...
Quality control 6.4.1 Standard work test Generally, standard work tests have to be carried out and supervised by the user before welding at a structure and after a certain number of welds has been made. The number of welds after which a standard work test is required is agreed upon with the customer.
Quality control 6.5.3 Tensile test The tensile test serves to test the metallic bond of the stud with the base metal. At least 3 studs are welded and then axially loaded by means of an appropriate tension device until they break. If the customer demands that a certain percentage of the welded studs should be tested with a specific test load in production, a tension device with load indicator should be used.
Contact the SOYER ® service department if necessary. 7.2 Replacement of components Defective components may only be replaced by trained SOYER servicemen. Perfect function of your stud welder can only be guaranteed when original SOYER spare parts are used. MORTAL DANGER Ensure that the capacitors are discharged before replacing any compo- nents.
Maintenance 7.3 Fuses The stud welder BMS-8N is protected by the following fuses: - Mains supply fuses: 2 x 10 A slow Plug-in unit (item 10, chapter 5.1) - Charging fuse F1: 6.3 A slow Control board S0-115 - Control fuse F2:...
