OPERATION

GENERAL DESCRIPTION

The Invertec® V205-T AC/DC™ is an industrial 200
amp arc welding power source which utilizes single
phase input power, to produce constant current output.
The welding response of this Invertec® has been opti-
mized for stick (SMAW) and TIG (GTAW). The unit is
ideal for industrial applications where portability is
important.
The Invertec® V205-T AC/DC™ is a power source that
can perform the following types of welding with excel-
lent results:
TIG (with high frequency or Touch Start Tig Starting).
• TIG AC with square, sinusoidal and triangular wave-
forms
• Tig DC
The following items can be connected to the 6 pin
socket on the front panel:
• Remote control potentiometer for Stick welding.
• Remote Foot Amptrol or Hand Amptrol
• Arc Start Switch
NOTE: See Accessories section of this manual for
product numbers and complete description.

WELDING CAPABILITY

The Invertec® V205-T AC/DC™ is rated at 200 amps,
18 volts, at 40% duty cycle on a ten minute basis. It is
capable of higher duty cycles at lower output currents.
It is capable of 140 amps, 15.6 volts at 100% duty
cycle. If the duty cycle is exceeded, a thermal protec-
tor will shut off the output until the machine cools. See
Technical Specifications in A-1 for other rated outputs.
The Invertec® V205-T is recommended for stick weld-
ing with such popular electrodes as Fleetweld 35,
Fleetweld 37, Fleetweld 180 and Excalibur 7018.
LIMITATIONS
The V205-T is not recommended for pipe thawing.
