SA6-1440H 6kg Payload 1440mm Welding Robot Arm Hollow Wrist Fast Arc Welding

Overview

• • The SA6-1440H 6kg Payload 1440mm Welding Robot Arm Hollow Wrist Fast Arc Welding unit is a six axis arc welding robot built by STEP on the SA welding platform.
• • The high speed version of this model delivers a fifty percent increase in working speed over the previous generation, which shortens the travel between weld passes.
• • A hollow wrist routes the torch cable inside the arm, so the cable no longer swings free at the tool flange and wire feeding stays smooth at every wrist angle.
• • Repeatability of plus or minus 0.05mm and trajectory accuracy below 0.4mm keep the wire on the joint line during long continuous welds.
• • The end linear velocity reaches 2.5 m/s, which supports long travel moves between fixtures without adding cycle time.
• • The SRC4S integrated drive cabinet is IP54 rated and up to eighty percent smaller than a conventional cabinet, which frees floor space beside the fixture.
• • Twenty four digital and four analog communication channels plus mainstream fieldbus protocols connect the torch, wire feeder and safety circuit through one controller.
• • The arc welding package covers arc tracking, wire positioning, multi layer and intermittent welding, and the controller supports multi machine collaboration and axes linkage.

Why the SA6-1440H speeds up arc welding cells

• • Fifty percent higher working speed shortens travel time between weld passes.
• • Hollow wrist with internal torch cable prevents cable swing and wire feed faults.
• • 0.05mm repeatability and 0.4mm trajectory accuracy hold the wire on the joint line.
• • End linear velocity of 2.5 m/s keeps long approach moves inside the cycle.
• • SRC4S cabinet is IP54 rated and up to eighty percent smaller than conventional units.
• • Twenty four digital channels connect torch, feeder and safety circuit without extra modules.
• • Arc tracking and wire positioning packages are included as standard process functions.
• • Brake hold on power failure keeps the arm from dropping during an unexpected stop.

Applications

• • Thin to medium plate arc welding of steel and stainless parts.
• • Welding cells with a servo positioner and coordinated axes linkage.
• • Multi machine welding cells with one operator and shared controller.
• • Frame, bracket and enclosure fabrication with frequent changeover.
• • Cutting and handling tasks on the same SA platform.
• • Retrofit welding cells that need a compact IP54 control cabinet.

FAQ

What makes this model faster than a standard welding robot?

The high speed version of the SA6-1440H delivers a fifty percent working speed increase, and the 2.5 m/s end linear velocity removes most of the travel time between weld passes.

Why does a hollow wrist matter in arc welding?

The torch cable runs inside the wrist instead of swinging outside the arm, which keeps wire feeding smooth, prevents cable wear at the flange and reduces interference with fixtures.

What welding process functions are included?

Arc tracking, wire positioning, multi layer welding and intermittent welding are part of the standard arc welding package, along with multi machine collaboration and axes linkage.

Which controller and cabinet come with the robot?

The SRC4S integrated drive control cabinet, IP54 protected and up to eighty percent smaller than a conventional cabinet, with 24 digital and 4 analog communication channels.

Can additional axes be added?

Yes. The controller supports 4 to 8 additional axes, and the SRC4F extension cabinet drives up to 6 external axes with power from 400W to 5.5kW.
