Spatter resistant surface.
Displays - Two digital LED displays with .56" (14.2
mm) character height. Top (3-1/2 digit) displays
Preset and Actual (while welding) arc voltage in volts
with (+) or (-) polarity indicators, and also displays all
timers in seconds. Bottom (4 digit) displays preset
wire feed speed in IPM, or m/m, and acceleration
selection.
Indicator Lights - Extra bright red LEDs for viewing
at almost any angle. Always indicate the feeder and
procedure selected, trigger mode being used and
function or timer being displayed.
Rotating Encoders - Knob controls increase or
decrease settings of volts and wire feed speed. (ini-
tially factory set to minimum) Alternately, the top
encoder adjusts timer settings and bottom selects
acceleration settings when selected for these parame-
ters to be displayed.
Power-Down Save
Power to the DH-10 is supplied and controlled from
