GENERAL DESCRIPTION

The Invertec® V311-T AC/DC is an industrial 310 amp arc welding power source that utilizes single or three phase input power, to produce constant current out- put. The welding response has been optimized for stick (SMAW) and TIG (GTAW). The unit is ideal for industrial applications where portability, high efficiency and premium arc performance is important.

The Invertec® V311-T AC/DC is a power source that can perform the following types of welding with excel- lent results:

•TIG AC with square, sinusoidal and triangular waveforms.

•TIG DC (with high frequency or Touch Start TIG Starting)

•Stick DC & Stick AC

WELDING CAPABILITY

The Invertec® V311-T AC/DC is rated at 310 amps,

22.4volts, at 40% duty cycle on a ten minute basis when connected to a 460V three phase supply line. It is capable of higher duty cycles at lower output cur- rents. 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® V311-T AC/DC is recommended for stick welding with such popular electrodes as Fleetweld 5P and 5P+ (E6010), Fleetweld 35 (E6011), Fleetweld 37 (E6013), Fleetweld 180 (E6011) and Excalibur 7018.

LIMITATIONS

The Invertec® V311-T AC/DC is not recommended for pipe thawing.
