3 Arc Stud Welding Inverter Machines KOCO Stud Welding equipment Inverter Technology 905i combines excellent welding characteristics with low weight, minimum size and outstanding performance. It is the ideal equipment for mobile tasks or stud welding on thin workpieces. The welding current setting is infinitely variable and the selected setting is maintained with high accuracy throughout the welding process. Welding time can be set in steps of 1 ms, thus enabling adjustment of the welding energy with an extremely high degree of accuracy. Fusion penetration is kept extremely low in spite of the high current (short cycle stud welding). All parameters can be set by turning a sturdy rotary knob with a builtin pushbutton and can be followed on an illuminated LC display. Up to 20 sets of parameters can be stored (welding current, welding time and shielding gas preflow time), which facilitates correct parameter setting in case of recurrent welding tasks. Deviations from the normal mode are shown on the appliance by a red pilot lamp, and simultaneously on the display in plain text (self diagnosis).
