Adjustable features make the Model DMA easy to operate.
The trailing coil end is sheared, then positioned in the
weld station. The leading end of the second coil is sheared
and then positioned in the weld station. Welding is automatic,
using either tungsten inert gas (TIG) or metallic inert
gas (MIG) and features a variable-speed, solid-state DC
motor drive and control.
Other features include reversible shear knives and weld
backup bar. Shear and weld clamps are die set type and
are hydraulically operated. Edge alignment guides have
hardened, replaceable faces and are adjustable. The automatic
weld carriage is supported on four ball bushings for precise
alignment.
THE TAB MODEL DMA SEMI-AUTOMATIC SHEARWELDER
The TAB Model DMA Shearwelder is a modified version of
the DMA for precision welds on narrow, thin gauge materials.
It is used primarily on single traverse wind or press
feed lines, where a perfect edge-to-edge weld is required,
on narrow strip, from about .187" (4.75 mm) to 7" (180
mm) wide.
The Guild exclusive TAB pusher feature allows the operator
to make consistent high quality edge-to-edge welds on the
narrowest and thinnest materials. Extra-long, completely
contained side guides are also provided to assure proper
strip alignment in the machine.
