CMT Twin

/ VR 1550 wirefeeder with 4-roller drive for smooth, precision feeding of the filler metal – regardless of where the wire is being fed from (bulk wire container or wire-spool) / Developed specifically for CMT Twin, the torch holder allows the two CMT Drive motors to be arranged in a way that minimises the obstacle contours. / A tandem torch optimised for the high-performance power range, the new Twin Compact Pro is highly versatile. This is made possible by the perfectly matched torch packages. The compact design of this water-cooled torch, with its two mutually insulated electrodes, provides very good weld accessibility. / The rugged and reliable FK 4000-R cooling unit is designed to dovetail with the modular concept of the welding system as a whole. / The two digitally controlled CMT welding power sources are perfectly attuned to one another by the unique system/process technology of CMT Twin. They come with a package of ideal characteristics covering every possible application.。

Robacta Twin 600----the smallest twin welding torch in the world

  • Fronius has once again managed to shift the limits and amaze the welding world. The Robacta Twin 600 is the world’s smallest twin welding torch in the under 600A power category. Whereas the use of twin welding torches was formerly often associated with space problem (e.g narrow gap), the new Robacta Twin 600 impresses with its compact dimensions. Even the tightest component geometries with gap widths in excess of 60mm are now possible for twin applications.

    Please note: Wearing parts are not compatible with conventional twin welding torches.

      Power, speed and efficiency: CMT Twin, a fast, low-spatter, tandem process.

      / CMT Twin is based on the same set-up as the tried-and-tested TimeTwin process: two power sources, one torch andtwo insulated contact tips (‘Lead’ and ‘Trail’), which have been added theoutstanding welding properties of CMT.CMT Twin scores top marks for its high welding speeds and easy-to-use process control.

      characteristic:

      /  The ‘Lead’ electrode is in pulsed-arc mode, and the ‘Trail’ electrode (in CMT mode) fills the weld-pool to the required ‘a’-dimension. Minimal mutual influence of the arcs, and a stable weld-pool, are among the defining features of this process.

    CMT TWIN welding process

  • Easy use

    / The synchronised start creates immediately a stable arc

    / Leading and trailing electrode work together harmonized

    / Minimal configuration times because of perfect welding characteristics

  • Cost saving

    / welding performance: less spatter, lower heat input, good gap-bridging ability

    / Significantly higher welding speeds

    / Deposition rate; up to 20 kg/h

    / Highest process stability over the entire power range TWIN

    / Deeper penetration

    / Easy handling (trail is self-regulating - CMT)

  • Maximum process stability

    / Less arc interference; Lead burns on the base material, trail fills up

    / Large differences in lead / trail wire feed speeds possible... ...excellent control of the deposition

    / Maximum process stability across the entire Twin power range

  • Light-gauge applications < 3 mm

    / Focus: Welding speed

    / Sectors:Automobile and component supply industry

  • Thick-gauge applications > 3 mm

    / Focus:Deposition rate

    / Sectors:Yellow goods、Shipbuilding、Power station construction

/ CMT Twin also has huge potential for welding with CO2 gas. It not only offers low-spatter welding results due to the perfect droplet detachment that is typical of the CMT process, but also a graduated choice between twice the welding speed and twice the deposition rate, as required.

/ In addition, CMT Twin comes with optimally fine-tuned characteristics for every application. Extra-thick materials are best welded with the ‘Heavy Duty’ characteristic. CMT Twin Speed is superbly well-suited for thin and ultra-light gauge sheets and/or the very highest welding speeds.

/ The new and extremely robust heavy-duty torch Twin Compact Pro allows good accessibility to the weldments. In addition, there are torch packages that are optimally tailored for every application.
