GENERAL DESCRIPTION
The Invertec V310-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 V310-T AC/DC is a power source that can per-
form the following types of welding with excellent
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 V310-T AC/DC is rated at 310 amps,
22.4 volts, 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 V310-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 V310-T is not recommended for pipe thawing.
