Description
About this machine
EWM Tetrix 230 AC/DC comfort 2.0 puls is a single phase TIG AC/DC station for precise work on aluminium, thin material and detailed parts. It runs from a 230 V socket and tolerates a wide voltage swing, so it also works behind a weaker supply or a generator.
Main data:
TIG welding current 3 to 230 A, 230 A at 40 % duty cycle, 200 A at 60 %, 170 A at 100 % at 40 degrees C
MMA welding current 180 A at 40 % duty cycle, 150 A at 60 %
mains supply 1 x 230 V, 16 A, tolerance from minus 40 % to plus 15 %
dedicated cooling unit filled with blueCool coolant
pulse up to 15 kHz, activArc, spotArc and spotmatic tacking
set includes an original EWM torch of 8 m with control in the handle
The set is used and shows normal marks of workshop service. Before sale it was checked in our own service workshop in Krotoszyn against current standards.
