100kg Payload 2236mm Reach 6 Axis Spot Welding Robot 0.03mm Repeatability

100kg Payload 2236mm Reach 6 Axis Spot Welding Robot 0.03mm Repeatability

Product Overview

Door and closure lines ask for two things at once: enough wrist strength for a servo gun and enough speed to keep pace with the framing station. This spot welding robot answers with 721 N.m of wrist torque and 175 deg/s of wrist rotation, so the gun swings between welds without the arm waiting on itself. The 100kg payload carries gun, transformer and cable package, while the 2236mm reach covers a full door aperture from a single floor position. At +/-0.03mm the arm repeats tightly enough that flange edge welds stay rare even late in a tip dressing cycle. The 660kg body mass keeps vibration low when the gun closes, which matters on thin outer panels where a sprung gun shows up as a dent.

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 100 kg, so the gun, transformer and cable package fit inside one load figure. The 2236 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

• 100kg payload carries a servo gun, transformer and cable package in one wrist load.
• 721 N.m wrist torque suits long electrode arms on door and closure guns.
• 2236mm reach covers a complete door aperture from one floor position.
• 175 deg/s wrist rotation shortens the air move between successive welds.
• +/-0.03mm repeatability limits edge welds as tips wear.
• 660kg body mass damps gun closing force on thin outer panels.
• IP67 wrist survives spatter and cooling water on high duty closure lines.
• Single supply cable and battery-free encoder backup simplify cable changes.

Typical Applications

• Door inner and outer panel welding
• Tailgate and hood closure lines
• Front end module sub-assembly
• Seat back frame welding
• Respot stations after hemming
• Mixed model closure lines with gun change

Frequently Asked Questions

Q: How much gun weight can the 100kg payload take?
A: The 100kg includes gun, transformer and cable package. A typical servo gun package for closures runs 55 to 75kg, leaving margin for a tip changer on the wrist.

Q: What makes this model faster than a standard 6 axis arm?
A: Wrist rotation reaches 175 deg/s and the gun axis is driven in parallel, so the arm does not wait for the wrist to settle between welds.

Q: How far does the 2236mm reach go?
A: It covers a full door aperture or a hood from one floor position, including the hinge and latch ends, without moving the fixture.

Q: Is +/-0.03mm enough on thin panels?
A: Yes. The limit is usually gun deflection rather than robot repeatability, and the 660kg body mass helps by damping the closing shock.

Q: How is the cable package handled?
A: A single supply cable runs to the base and the wrist cable package is supported by the cable handling flange, so a cable change does not require re-mastering.

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

Q: What lead time applies to this model?
A: Around 35 to 45 days after deposit, including export packing, with commissioning support available remotely or on site.

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.
