The KUMJR315AC/DC is a 240V square wave AC/DC TIG inverter welder incorporating full TIG functionality including AC balance
control, pre gas, down slope, post gas, variable pulse parameters, HF start with 2/4T trigger control. The HF arc start provides easy
arc ignition leaving no tungsten inclusion and no contamination of the tungsten electrode. The Down Slope and Post Gas combined
with the 2/4T trigger function gives you control of the welder allowing you to control the start and finish of the weld process at a profes-
sional level. The addition of a fully adjustable pulse function of frequency, base current and pulse width gives you the added capability
to better control heat input into the work, control penetration & control distortion. AC balance control lets you set the AC TIG arc for
cleaning of the oxide layer on aluminium and adjustment for a deeper penetrating weld. Combining the functions of the KUMJR315AC/
DC ensures comprehensive control of the welding parameters when welding both AC and DC weldable materials giving you the abil-
ity to produce professional Tig welds. The DC MMA welding capability delivers a smooth and stable arc allowing easy welding with
electrodes obtaining high quality welds including cast Iron, stainless and low hydrogen. Addition of the optional Foot Control provides
variable amperage adjustment during welding. The UNI-MIG KUMJR315AC/DC has set the benchmark for 240V single phase AC/DC
welders and made it ideal for multiple applications; aluminium & stainless steel fabrication, light industrial use, repair and maintenance
applications. Robust & reliable, built to our specification and manufactured in compliance to AS/NZ60974.1
