than

the

regular 'blowing out'

lubricated

with

will

not

require

any

maintenance procedure.

To

remove

the

hence the mutor

is

contr.al1ed

tly

the circuitry contained on

the printed circuit board

W16-20.

The desired wirefeed mator.

speed

is

determined

by

the setting

of

the

wire speed potentiometer.

The proces5ed potentiometer wiper

This

is

applied

tu

the pin

input of the cumparator

IC2/1,

where

it

is

compared to the potentiometer wiper uol tage.

The

difference between these two uul tayec is amp1 ified

by

IC2/1

and

the resultant uoltage applied to the pin

input

sf

IC2/2,

where

it

is. compared

to

a

mains synchronized

waueform. The result of

this comparison determines the conduction angle of the

SCR’s

and hence the motor speed.

The

ouer-all

effect

is

such that,

if

If
