REASSEMBLING THE MAIN TRANSFORMER INTO THE MACHINE
NOTE: The following procedure assumes you have completely reassembled the transformer coils as described in the procedure above. The lower iron has remained in place in the machine. See Figures F.25 and F.26.
1.Resolder the choke control coil leads to the arc control switch.
2.Attach the bottom choke lead to the negative recti- fier plate.
3.Attach the top and center choke leads to the mode selector switch.
REASSEMBLE THE LIFT BAIL
1.Carefully position the lift bail onto the machine base. Using the 9/16” socket wrench, attach the lift bail to the base of the machine with four bolts, flat washers, and lock washers.
2.Using the 9/16” socket wrench, attach the lift bail to the transformer top and bottom irons with four bolts.
3.Attach the sheet metal screw that holds the capacitor bank assembly to the case back.
4.Connect leads #204 and #227 to resistor R3.
5.Connect lead #204 to resistor R2.
6.Connect the negative capacitor strap to the mode selector switch.
7.Connect the positive capacitor strap to the output shunt.
8.Attach the two leads to resistor R1.
9.Attach the fiber baffle to the left side of the choke.
10.Attach the two fiber baffles to the left and right sides of the lift bail, adjacent to the main trans- former.
11.Install the machine case top and sides.
