ELECTROSTATIC VOLTAGE

The MMA-570 Indirect Applicator receives a low

voltage control input from the MicroPak to control

the operating electrostatic voltage. (Refer to the

current MicroPak manual for detailed Operating

Instructions.) Refer to the current MicroPak service

manual for detailed operating instructions, safety

cautions, and settings.

TARGET DISTANCE

The distance between the MMA-570 atomizer

and the target will affect the finish quality and

efficiency. Closer distances give a smaller pat-

tern, wetter finish, and greater efficiency. Greater

distance will provide a large pattern size and drier

finish. The MicroPak control circuit will enable

the applicator bell to be operated to within a few

inches of the target without adjusting the voltage

setting. The recommended target distance is 6

to 12-inches (152.4-304.8mm). In general, allow

1-inch (25.4mm) target distance for every 10kV.

NOTE

†

If paint defects occur, such as fat-

ty edges or picture framing, reducing

the voltage should be a last resort. To

correct the problem, lead and lag trigger

adjustments should be optimized first.

†

The electrostatic voltage applied to

the MMA-570 will affect pattern size,

transfer efficiency, wrap and penetration

into cavity areas. A setting of 30-70 kV

is appropriate for most direct charge ap-

plications and 30-70 kV for most indirect

charge applications.
