the TR-23 Truck.
7. Current (Slope) Control Module, with Trigger Lock, P/N 36228. Allows
setting of start (initial) current, up-slope time, down-slope time, and final
current, as well as standard or latching torch trigger.
NOTE: When using pulse and/or slope control, dip switch settings on main
control board must be reset, see 4.1.6 in the Maintenance section.
8. Pulse Control Kit, P/N 36227. Allows independent setting of Peak Current
(I1), Peak Time (T1), Background Current (I2), Background Time (T2). Has
a three position switch for setting Peak (I1), Background (I2) and Pulse
modes.
9. Power Factor Kit, P/N 36220. This kit when installed in power source will
