A stored energy welding machine ____? obtains energy from the service lines at a relatively fast rate obtains energy from the service lines at a relatively slow rate releases energy for welding at a slow rate causes a Cooling water for a resistance welding machine should be supplied at a temperature of ____ or less. 85°F 212°F 32°F 50
The general heat generation formula for resistance welding is: Heat = I2 x R x t x K. Where "I" is the weld current through the workpieces, "R" is the electrical resistance (in ohms) of the workpieces, "t" is the weld time (in hertz, milliseconds or microseconds), and "K" is a thermal constant. The weld current (I) and duration

Mechanical hazards. Resistance welding is extensively used for guillotined, blanked or pressed components which may have very sharp edges or burrs. The incidence of cuts and lacerations can be minimised by deburring the components before they are taken to the welding position and by wearing protective gloves or gauntlets. Resistance welding
Resistance welding is used to join two metal objects. In this process the objects to be welded are heated by resistance heat generated when the workpieces are sandwiched between welding electrodes that are passing current through them. The workpieces are pressed together between the electrodes and the metal is welded while pressure and
