over a narrower range. The high setting provides less
sensitivity but yields a wider range.

4.07 Changing Meter Functions
The Portafeed VS 212 has two digital meters on the
front panel. The top meter always displays the welding
power supply's voltage output. However, the lower
meter can be set to display either the wire feed speed
or the welding power supply's current output.
Furthermore, when it is set to display the wire feed
speed, an additional setting can be made to display
this parameter in either inches per minute (ipm) or in
meters per minute (mpm). Refer to Figure 4-6.
