11. APPLIED FUNCTION (continued)
WARNING
Follow the instructions below to avoid electric shock.
Touching charging parts may result in critical electric shock and burn.
●
Do not touch charging parts either inside or outside the welding machine.
●
Have a qualified person adjust a variable resistor.
●
Be sure to disconnect all of the input power source with the line disconnect switch of the
power box when touching parts inside of the machine.
11.2 External connection with terminals inside of the welding power source
●
12P terminal block is located inside the front cover of the welding power source.
The functions of the terminal block are as illustrated below.

1 When using a wire feeding except L-6990 and L-7160, connect the arc voltage detective wire to
this terminal. When using L-6990 and L-7160, make no connection to this terminal.
2 To retract wire by external signals. (When terminals are short-circuited, wire is retracted.)
3 To perform inching wire by external signals. (When terminals are short-circuited, wire is
inched.)
4 This terminal is used to start welding from external signals.(When terminals are short-circuited,
weld starts.)
Note: 2, 3, and 4 are available when CURRENT / VOLTAGE CONTROL knobs set to PANEL.
