Spot welding robot with built-in cables

SRA100HS/SRA100HB

Cable built into the hollow arm
Welding cables and hoses packed tightly insidearms with hollow construction■ Avoids interference with surrounding equipment

through the displacement of cables■ Improved reliability and safety of cable

performance through wrist operations■ The embedded welding cables in the arm makethe off-line programming easierCompact body
■ Minimized robot height so it can be used in

multilevel arrangements

LOCUS(POINT A)

1 [rad] = 180/π [°], 1 [N·m] = 1/9.8 [kgf·m]*1:This value changes by placement and load conditions of a wrist.
*2:The Allowable moment of inertia of a wrist changes with loadconditions of a wrist.
*3:This value conforms to “JIS B 8432”.
*4:Permitted height is not higher than 1,000m above sea level. If usedin higher place, permitted temperature is affected by height.
*5:A-weighted equivalent sound level measured according to JIS Z
8737-1 (ISO 11201). (while operating at maximum speed with ratedload)
