350 AC/DC H F tig In ver ter :
The 350 AC/DC is an AC/ DC microprocessor controlled IGBT inverter with Constant Current (CC) output
characteristics. Designed for HF TIG AC/DC, LIFT-ARC TIG AC/DC and STICK welding in DC,
the 350 AC/DC operates on three phase 400 volt primary input voltage.
This unit is supplied with a heavy duty inverter cart and water cooler as standard and is a true full
function AC/DC TIG and STICK welding machine for all medium to heavy industrial applications. This
truly full function AC/DC TIG and STICK welding machine has automatic hot start and arc force control,
adjustable pre-flow and post-flow gas control, independent slope up and slope down control, down
slope repeat function, 2/4 step torch switch control, adjustable AC frequency and AC wave balance
control, full feature built in pulse facility and large display digital meters for current and voltage..
