The CRUXWELD DynaTwin 200M is a dual torch welding carriage for long parallel seams such as box-beam reinforcements. Two MIG/MAG torches, 300–850 mm apart, weave together from one control panel while the magnetic, guide-wheel carriage rides the beam — no track to lay.

On a box beam or a long reinforced member, the same weld runs twice — once on each side. Done by hand, that is two welders, two travel speeds and two different beads. The DynaTwin 200M puts both torches on one carriage, so both sides are welded in the same pass with the same speed and the same weave.
A permanent magnet holds the carriage to the steel and two pairs of guide wheels — one horizontal, one vertical — run against the walls and plates of the beam to keep both torches on their seams. Each torch has its own X-Y slide for fine placement, and both are set from a single control panel.
A + B. Both corner seams are welded in the same pass — same travel speed, same weave, one control panel.
Torch A only. The carriage runs with one torch for a single seam; torch B stays parked.
Torch B only. Weld the other side alone, without moving the carriage across.
Set both torches to the same wire and welding specification so the two seams come out matched.
The DynaTwin 200M is at its best wherever the same long, straight weld appears on both sides of a member:
One-off jobs, curved paths or a single seam? A single-torch carriage is the simpler choice — see the comparison below.
