GENERAL DESCRIPTION
The V160-T is an industrial 160 amp arc welding power
source which utilizes single phase input power, to pro-
duce constant current output. The welding response
of this Invertec has been optimized for stick (SMAW)
and Touch Start TIG (GTAW). The unit is ideal for
industrial applications were portability is important.
The Invertec V160-T performs DC TIG with high fre-
quency or Touch Start Tig Starting with excellent
results.

WELDING CAPABILITY
The Invertec V-160-T is rated at 160 amps, 26.4 volts,
at 35% duty cycle on a ten minute basis. It is capable
of higher duty cycles at lower output currents. It is
capable of 130 amps, 25.2 volts at a 100% duty cycle.
If the duty cycle is exceeded, a thermal protector will
shut off the output until the machine cools.
Technical Specifications in AA-2 for other related
outputs.
The Invertec V160-T is recommended for stick welding
with such popular electrodes as Fleetweld 35,
Fleetweld 37, Fleetweld 180 and Jet-LH 78 MR. It fea-
tures adjustable arc control to adjust the arc force and
start.
LIMITATIONS
The V160-S is not recommended for pipe thawing.
