FAMILIARC™ SE-A50FS: Beautiful Flat and Expansive Beads

Excellent bead contour in high speed welding, such as 9デュエルビッツ評判40cm/min, without humping and undercut.
Welding slag is condensed in one spot, not dispersed, and low in quantity.
Its flat, wide bead shape is less likely affected by デュエルビッツ評判arameter, and more tolerble to deviated wire tracking.

FAMILIARC™ MIX-1TR -the Solid Wire to Improve Electrodeposition Coating Property

FAMILIARC™　MIX-1TS provides the weld with improved electroposition coating properties with the exsititing equipment.
Undercut is not likely to occur at the toe of the welded bead even in the welding of sheets with gaps.
Bead configuration is not likely to become convex even in high speed welding.
Stable welding with little spatter is possible by selecting optimum デュエルビッツ評判arameters.
