NOTICE
Indicates statements not related to personal injury.
Indicates special instructions.
Welding sparks can cause fire or explosion. Move flam-
mables away. Do not weld on closed tanks or barrels −
they can explode. Clean tanks or barrels properly.
Beware of electric shock from welding electrode or wiring.
Touching the electrode while in contact with the work or
ground can cause electric shock. Always wear dry
gloves. Keep all panels and covers closed.
Breathing welding fumes and gases can harm your
health. Welding requires good ventilation. If ventilation is
impossible, such as when welding in a confined space,
use an air-supplied respirator.

2. Specifications and Location
ST-086 923-C
This unit is an interface control de-
signed for use with a DIALARC®
HF welding power source. This in-
terface control provides a connec-
tion point for a remote contactor and
amperage control device (not
supplied) such as an FTC-23,
RFCS-23, or equivalent. The nec-
essary interconnecting cords are
supplied with this unit to connect it
to the welding power source.
This control is equipped with two 6
ft. (1.8 m) cords for making connec-
tions to the welding power source
control circuitry. Lead lengths must
be considered when locating the
control. The control can be placed
on top of the welding power source
or at a nearby location.
The service life and efficiency of the
control are reduced when it is sub-
jected to high levels of dust, dirt,
moisture, corrosive vapors, and ex-
treme heat.
