Overview

Like the standard reach B4S, the same through-arm design is applied to the B4LS for tight welding requirements or the need for floor space savings but on a larger scale. This long reach (L) robot is perfectly suited for larger, distant or multiple welding zones.

Arc Welding Robot

• Rotation of the seventh axis enables interference avoidance without changing the position and/or attitude of the tool.
• Maintaining the optimum attitude at all times results in the enhancement of weld quality.

Teach Pendant

• Icon displays assist in quick & easy teaching
• 640x480 VGA color screen with LED backlight 65536 color display
• 3 position enable switch provides increased safety
• Multi-screen function allows user to view up to 4 screens simultaneously
• On-screen help function with complete instruction manuals
• Standard touch screen display with jog dial operation
