A special device (patent pending) clamps the rolled body throughout its complete welding lengths and guarantees a constant overlap. The WIMA – seam looks better, removes all the flanging and seaming problems and allows even a powder or lacquer coating.
Since the handling system is based on a clamping device, even irregularly cutted blanks, such as out of square or too long and too short can’t create any overlapping problem (except “bow cuts”).
The greatest advantage of a semi-auto-welder is its great flexibility even for smallest can orders. Diameter change on a CM 21 requires no changeover time and canbody height changes can be done in less than a minute.
This semi-auto is the smallest welder ever built. With a floor size of only 1 x 1 meter it was never as easy to move this machine from one place to another. With the optional available cooling unit and the 2 plugs (electric and air) you can move it easily wherever you want it in no time.
