3.0 BASIC OPERATING PARTS
3.1 WELD HEAT SELECTION SWITCH
Weld heat is selected by means of a tap switch with 10
steps of voltage. Number one indicates the highest setting
and number ten the lowest. The switch is located in the
front and center of the welder. (Ref. 4.0)
3.2 HEAD CLOSED SPACE SETTING
Turning the insulated screw that rides the space-adjusting
cam located on the top of the headpiece makes this
adjustment.
3.3 HEAD OPEN SPACE SETTING
A space-adjusting cam located on the top of the headpiece
makes this adjustment. This setting determines the amount
of burr that the weld will have. See charts for
approximate settings.
3.4 LIMIT SWITCH SETTING
The weld limit switch controls the cutoff point of current
flow to the welding dies. Turning an adjusting screw
located on the left end of the movable headpiece makes this
adjustment. See Charts for setting.
3.5 UPSET PRESSURE
Upset pressure adjustments are obtained by rotating the
knurled knob on the right hand side of the stationary
headpiece. When the outside edge of the adjusting screw is
flush with outside edge of the knurled knob, the movable
headpiece should just close when pulled to the left by hand
and released. A calibrating screw and nuts located on the
opposite left hand headpiece will assist in setting this
positioning. Accompanying charts will assist in correct
settings for various sizes of wire.
3.6 WELD INITIATING KNOB
The push button knob that initiates the weld cycle is
located on the right front of the welder enclosure.
