SPEED CONTROL: Sets the tractor weld speed from 2-120 in/min (5.1-304.8 cm/min).
CARRIAGE TRAVEL SWITCH: Provides FORWARD/STOP/REVERSE direction control.
DIGITAL READOUT: The display is dual function.
a) PRESET SPEED - Displayed when the CARRIAGE TRAVEL SWITCH is OFF
or motion is halted by a motor overload condition.
b) MEASURED SPEED - Displayed when power is applied to the motor. (This will
be the same as the Preset Speed.)
Factory settings of 120 Volt machines are set to in/min, 240 and 42 Volt machines are set cm/min.
WELD CONTACT: Opens/closes a pair of independent 1 Amp contacts (pins A & B and C & D) at the
weld contactor receptacle. In STITCH mode, this switch acts as a weld contact en-
able and the stitch module cycles the contacts on and off.
NOTE: A safety interlock will automatically open the weld contacts if the motor overload protection halts
machine motion. Clear the overload by turning the carriage travel switch to OFF. Resetting the
overload fault will not cause the contacts to automatically reclose. Use the weld contact switch to
restart the welder after clearing the overload.
MDS-1003 STITCH MODULE
The MDS-1003 Stitch Module provides direction and speed control for continuous welding and cutting. In
addition, a stitch welding mode is provided, with adjustments for skip time (welder off), weld on time and
puddle buildup/crater fill time.
