180kg Payload 2702mm Reach 6 Axis Hollow Arm Spot Welding Robot 0.05mm

Product Overview

When a servo gun with its transformer sits on the wrist all shift, cables are the first thing to fail, and this hollow arm model is built to remove that failure mode. Gun cables and air lines run through the arm structure instead of looping outside, so there is nothing to snag on the body aperture or on a neighbouring robot. The 180kg payload covers a transformer mounted servo gun with a long electrode arm, and 1000 N.m of wrist torque plus 104 kg m2 of inertia keep the gun from drifting as it rotates between welds. Reach is 2702mm, which covers a full body side from a single floor position, and the 1090kg body mass keeps the structure settled through the gun closing shock.

Selection Guide

Choosing a spot welding robot in this class usually starts with gun mass, then reach, then body mass. This spot welding robot is rated at 180 kg, so the gun, transformer and cable package fit inside one load figure. The 2702 mm reach of this spot welding robot then sets how many stations a body needs, and here it is one. Because a spot welding robot is judged by its welds, we quote the gun package, controller and parameter backup together, and we check the reach envelope against your line drawing before the spot welding robot is packed for shipment.

Key Specifications

Advantages

• Internal cable routing removes the external loop that snags on fixtures.
• 180kg payload covers a transformer mounted servo gun with a long arm.
• 1000 N.m wrist torque keeps the gun steady through each rotation.
• 104 kg m2 wrist inertia suits heavy electrode arms on high duty lines.
• 2702mm reach covers a complete body side from one floor position.
• 1090kg body mass damps the closing shock of a large servo gun.
• IP65 wrist with internal cabling survives spatter without extra wrapping.
• Cable replacement does not disturb origin data, so downtime stays short.

Typical Applications

• Body side framing with transformer mounted guns
• Underbody welding with heavy servo guns
• High duty two shift body shop lines
• Roof and pillar welding near fixtures
• Cells with restricted space around the wrist
• Lines running long electrode arms for deep flanges

Frequently Asked Questions

Q: What is the advantage of the hollow arm on this model?
A: Gun cables and air lines run inside the arm. On a heavy gun package that removes the external loop, which is where most cable failures and snags start.

Q: How much gun weight does 180kg allow?
A: A transformer mounted servo gun with a long electrode arm typically runs 110 to 140kg, leaving margin inside the 180kg wrist rating.

Q: How much inertia can the wrist turn?
A: 104 kg m2 on the R and B axes. Long electrode arms have high inertia, and this rating is what stops the gun drifting at the end of a rotation.

Q: What reach does 2702mm give?
A: A complete body side from one floor position, including rocker, pillar and roof rail joints. For longer bodies we confirm the station split from your drawing.

Q: Does internal cabling complicate maintenance?
A: It simplifies it. Wrist cables are changed from the arm without re-mastering, and the structure protects the cables from spatter.

Q: Which controller is supplied?
A: The YRC1000 controller with spot welding software, gun pressure control and weld schedule management in a 125L cabinet.

Q: What is the typical lead time?
A: 35 to 50 days from deposit, with drawings issued for approval and commissioning support available on site or remotely.

Q: How do I confirm this spot welding robot fits my cell?
A: Send the gun package and the station drawing. We check the reach envelope of this spot welding robot against the fixture layout and return a layout with this spot welding robot placed to scale, usually within two working days.
