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 optimized 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 excellent 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 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 welding with such popular electrodes as Fleetweld 35, Fleetweld 37, Fleetweld 180 and Excalibur 7018.

LIMITATIONS

The V205-T is not recommended for pipe thawing.
