The saved results of the five test welds are averaged and transferred as reference values in the set program when exiting the operating mode "MEAS". The acquisition of reference values can be repeated at any time. The existing values are overwritten. Select the admissible deviation of the quality control Value TL = Tolerance 0 = Quality control off.
7 Quality control (stud welding) General instructions ® Provided the SOYER welding equipment is correctly 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.
7.2.3 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 means of a tube slipped over the stud. The test is successful when no superficial fissure or fracture is detected in the welding zone.
SOYER spare parts are used. 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 and appropriately qualified personnel.
