MIG/MAG multi-process welding machines

alpha Q

Advantages

Reduced-energy short arc

Reduced heat transfer – low distortion and

minimal heat-affected zone – perfect for

CrNi, super high strength steels and thin

panels

Only the best for welding and brazing

Steel, CrNi, aluminium and mixed connec-

tions with copper and zinc solders

Universal in any position

Perfect joins for all out-of-position welding

– overhead, vertical-down and vertical-up

welding, plus unprecedented gap ﬁlling

capabilities

Universally applicable

Manual and automated – with normal

commercial torch systems without elaborate

wire feed components.

High degree of process reliability

Reproducible, X-ray-proof root welding e.g.

in container and pipe construction

Outstanding results mean minimum ﬁnishing

Almost spatter-free – similar to TIG process,

excellent formation of root layers and cap-

ping runs, no undercuts
