100kg Payload 2236mm Reach 7 Axis Extendable Arm Spot Welding Robot IP67

100kg Payload 2236mm Reach 7 Axis Extendable Arm Spot Welding Robot IP67

Product Overview

The seventh axis on this spot welding robot sits inside the L arm, not at the wrist, and that changes what a cell can look like. Extending the E axis lengthens the arm by up to 320mm, so one robot reaches into a body side that would otherwise need a second station or a moving base. The result is a shorter line, fewer fixtures and less floor between stations, which is why compact layouts use this model instead of a larger 6 axis arm. Payload stays at 100kg with the cable flange fitted, enough for a servo gun and transformer, and +/-0.04mm repeatability is tight enough for production welding. The extra axis adds 130kg of body mass over the 6 axis version, so a standard floor anchor still applies.

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

• The E axis inside the L arm varies arm length by up to 320mm during the cycle.
• One 7 axis unit reaches areas that need two 6 axis stations.
• Shorter line length and fewer fixtures cut cell footprint and build cost.
• 100kg payload carries a servo gun, transformer and cable package.
• 2236mm reach with variable extension covers deep body side geometry.
• +/-0.04mm repeatability holds weld position through the extension stroke.
• IP67 wrist tolerates spatter on high duty framing and respot work.
• Standard floor anchoring is enough for the 790kg body mass.

Typical Applications

• Compact body side framing cells
• Deep sill and pillar welding
• Multi-model lines with one fixture set
• Respot stations with restricted floor space
• Door aperture welding from a single base
• Retrofit cells replacing two older robots

Frequently Asked Questions

Q: What does the seventh axis actually do?
A: The E axis sits between the L and U arms and extends the arm by up to 320mm. That lets one robot reach deep into a body side instead of adding a station or a track.

Q: Does the extra axis reduce payload?
A: No. Payload remains 100kg with the cable handling flange, the same as the 6 axis version, because the E axis is part of the arm structure.

Q: How much floor space does it save?
A: Layouts typically shorten by one station. We review your line drawing and return a layout comparison showing the reach envelope at full extension.

Q: Why is repeatability +/-0.04mm rather than 0.03mm?
A: The additional joint adds a small stack-up. In production welding the difference sits inside normal gun deflection, and weld schedules absorb it.

Q: Can it replace two robots in an existing cell?
A: On many respot and framing cells it does. We check fixture access and cycle time before confirming, since the E axis stroke has to cover both positions.

Q: What controller supports seven axes?
A: The YRC1000 controller drives all seven axes and stores palletizing and welding schedules. The teach pendant shows the extension axis separately for easy teaching.

Q: How is it shipped?
A: The arm travels braced on a steel base inside a plywood case, with the controller and pendant boxed separately. Typical lead time is 35 to 50 days.

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.
