Speed display shows the rate the LN-15 will feed elec-
trode during welding. The wire feed speed is calibrat-
ed to within ±2%.

2. VOLTAGE DISPLAY

-

The voltage display shows

the average arc voltage during the welding. The aver-
age voltage will continue to be shown for 5 seconds
after the end of the weld. When not welding, the dis-
play is "- - - ". The voltage is calibrated to ±2% over a
range of 10 to 45 volts.

A minus sign "-" will appear when welding with elec-
trode negative welding procedures.

DUAL PROCEDURE
The LN-15 supports a special "dual procedure" mode.
When activated, the wire feed speed is reduced to
83% of the set value, but no less than 50
inches/minute (1.27 m/min).

A Magnum 400 DP gun or equivalent is required to
activate the 83% dual procedure mode.
