The Hand Amptrol is a finger or thumb operated remote control, in a lightweight (14oz.) compact package that
attaches to a TIG welding torch handle. The Amptrol has a 28 ft cable with a 6-pin S-type connector (18-12P)
to connect to a power source or high frequency generating accessory. It is designed to fit any Lincoln TIG Torch.

* A minor modification is needed when K963 Hand Amptrol is used
with the V250-S. The braided ground strap must be disconnected
from connector body on end of cable that attaches to the machine.
Remove cable clamp screw securing grounding strap, remove strap,
and reinstall screw. Run grounding strap along side of cable so that
it does not contact connector body, and secure in place with electri-
cal tape.This modification is necessary in order to avoid coupling
electrical noise from the case of the machine onto the control leads,
which would otherwise result in poor starting and unstable welding
performance.

Place the hand Amptrol along the TIG welding torch
cable, as shown in figure 1. Slide the hand Amptrol
along the torch handle, so the control knob can be
extended conveniently by the thumb.

With power source off, connect 6-pin S-type
(Amphenol) connector to the Remote Receptacle if
available, or use required adapter. Secure with the
threaded collar*. The Amptrol is designed for use with
a 25-ft TIG torch. It is recommended that any excess
length be tucked under the power source.

------------------------------------------------------------------------
If a K915-1 adapter is needed (when using a high freq
kit) or the equipment has a plastic amphenol, a ground
lead must be fastened from the cable clamp screw on
the hand Amptrol to the mounting screw on the amphe-
nol as shown in figure 2.

Extend the knob forward to start the welding sequence.
Extending the knob increases the current. Extend the
knob fully to obtain the maximum set current. Retract
the knob to reduce the current. For equipment with out-
put contactor controls, fully retracting the knob stops
the weld and stops the welding sequence. Refer to the
power source and/or TIG accessories manual for spe-
cific operations instructions.

" SINCE THE FULL OUTPUT OF THE CUR-
RENT SETTING IS AVAILABLE WHEN THE
A PTROL IS FULLY EXTENDED, CARE
UST BE TAKEN NOT TO SET A CURRENT
WHICH WILL EXCEED THE CURRENT CAR-
RYING CAPACITY OF THE TUNGSTEN.
WHEN IN DOUBT, USE A LOWER CURRENT
SETTING FIRST, THEN INCREASE.
TO AVOID BEING STARTLED BY A HIGH FREQUEN-
CY SHOCK, KEEP THE TIG TORCH AND CABLES IN
GOOD CONDITION.
