SZGH-1406-A Easy Series Industrial Collaborative Welding Robot

What Is the SZGH-1406-A?

The SZGH-1406-A is a 6-axis industrial collaborative welding robot with a 6 kg payload, 1,460.7 mm armspan, and 3,000 mm/s tool-tip speed — the longest-reach model in the SZGH Easy Series — engineered to weld large-format workpieces such as door frames, long structural tubes, and aluminum panel assemblies in a single setup, while operating alongside human workers on the same floor under full IP65 whole-body protection, without safety fencing.

5 Core Advantages

1,460.7 mm Armspan — Easy Series' Longest Reach at the Lightest Weight

At 1,460.7 mm, the SZGH-1406-A extends 383 mm further than the SZGH-0907-A, yet weighs only 22 kg — just 1 kg more. For workpieces in the 1,000–1,400 mm range (window frames, door frames, structural channel, long tube runs), this reach eliminates the need to reposition or re-fixture mid-weld. Competitive long-reach cobots in this class typically weigh 28–35 kg, making single-person installation impractical. The SZGH-1406-A can be repositioned by two workers without lifting equipment.

3,000 mm/s Tool Speed — Long-Reach Without Long Cycle Times

Extending arm reach on a conventional cobot typically forces a speed reduction to maintain safe inertia limits. The SZGH-1406-A maintains the full 3,000 mm/s tool speed across its entire work envelope — up to 2–3× faster than collaborative robots in the same reach class. For a 1,350 mm door frame with four perimeter welds, this directly translates to higher daily output versus slower long-reach alternatives.

IP65 Whole-Body Protection — Built for Real Production Environments

The SZGH-1406-A carries IP65 protection across the entire robot body, not just individual joint seals. In aluminum welding applications, this is critical: aluminum oxide spatter is abrasive and fine enough to penetrate unsealed housings within weeks. Door and window frame fabrication shops also involve cutting fluid, aluminum dust, and humid air. IP65 whole-body sealing means the robot runs without degradation in these environments — no annual re-sealing maintenance, no joint failure from spatter ingestion.

6-Button Drag Teaching — Change Workpiece Variants in Minutes

Door and window manufacturers run multiple SKUs: different frame sizes, corner profiles, and customer specifications. Each variant requires a different weld path. With the SZGH-1406-A's drag teaching system, a welder physically guides the arm through the new path and saves it — in under 20 minutes, compared to several hours for a traditional robot programmer to reprogram a conventional system. Multiple weld programs are stored onboard; switching between SKUs is a single button press.

XI Black Box + 100-Point Safety Self-Check + 10-Level Collision Protection

The XI Black Box records complete motion and state data before and after every fault, enabling remote diagnosis without an on-site engineer. The 100-point startup self-check verifies mechanical and electrical integrity before the robot moves. Ten-level adjustable collision sensitivity keeps workers safe when inspecting work in progress beside the arm — the robot stops immediately on human contact and holds position. Safe stop is maintained even if the robot cable is cut, ensuring compliance with human-collaborative workstation safety requirements including ISO/TS 15066.

Selection Guide: Easy Series Cobot vs. SZGH H/HZ Traditional Welding Robots

Customer Story — By Fannie Chen, CEO, SZGH

The aluminum door factory in Thailand came to us with a very specific problem, not a vague automation wish.

They manufactured aluminum sliding door frames for export to Europe — single frames ranging from 1,200 to 1,350 mm in length, with continuous MIG welds running along all four perimeter edges. Their existing process used a conventional 6-axis welding robot with a 1,200 mm reach. The arm was just short enough that it could not complete the full 1,350 mm frame length in one setup. Workers had to unclamp the frame, reposition it, and re-clamp it for the second welding pass. That repositioning introduced a joint — a slight discontinuity in the weld bead at the splice point. It was barely visible, but visible enough that European building code inspectors flagged it as a potential structural weakness in certification testing.

The result: approximately 5% of shipments returned annually, with full freight cost borne by the factory. Their European buyer was also beginning to hint that a structural weld quality audit was coming.

The SZGH-1406-A's 1,460 mm armspan covers the full 1,350 mm frame length in a single uninterrupted pass. Combined with a rotary positioner on one EtherCAT external axis, all four perimeter welds are completed in a single fixture setup. No repositioning. No splice. Continuous bead, full length.

Beyond eliminating the splice, being a collaborative robot meant the factory's quality inspector could stand directly beside the robot during the weld cycle, watching the bead form in real time. If a wire feed issue or fit-up gap appeared, the inspector paused the robot immediately — no interlock, no waiting for the enclosure to clear. Response time to quality deviation dropped from minutes to seconds.

After deployment, return shipments dropped to zero. The European buyer's audit team came through six months later, reviewed the weld documentation, and not only cleared the factory but placed a larger order — citing improved structural consistency as the reason.

The factory owner told me: "The extra 380 mm of reach paid for the machine in four months."

That is the kind of math that makes sense to every factory owner I meet.

Control System & Integration

XI Controller — The Brain Behind Every Easy Series Robot

The SZGH Easy Series is driven by the XI (Xing-Intelligence) controller, engineered for collaborative welding in real production environments:

• EtherCAT bus at 1 KHz: deterministic real-time control with zero communication jitter — critical for maintaining bead consistency at 3,000 mm/s over a 1,460 mm path

• Up to 15 external axes: connect rotary positioners, linear tracks, or dual-arm configurations on one controller — ideal for the 1406-A's typical door frame application (arm + rotary fixture + optional linear rail)

• XI Black Box (industry first): continuously logs all joint positions, motor currents, I/O states, and error codes. When a fault occurs during a long welding pass, the complete pre-fault data record is available immediately for remote diagnosis — no engineer travel required

• Drag-and-Drop Teaching via 6-button handle: physically guide the arm through the weld path, record, save, and call up any stored program with one button press. When running multiple door frame SKUs, program switching is instantaneous

• 100-point startup self-check: runs automatically at power-on. Detects any mechanical or electrical fault before the robot moves — particularly important in high-duty-cycle applications where thermal stress is a factor

• 10-level collision sensitivity: fully adjustable. At the highest sensitivity, a light touch from a worker stops the arm immediately — enabling the quality-inspection-while-welding workflow that factory supervisors value most

Vision Integration for Large Workpieces

The SZGH-1406-A natively supports 2D and 3D vision through the tool port (EtherCAT + RS485 + AI×2):

• 2D seam tracking: for long straight and curved weld seams on door frame extrusions — real-time path correction for fixture tolerance variation

• 3D workpiece alignment: structured light point cloud scanning to locate the workpiece within the 1,460 mm work envelope before welding begins — eliminates dependence on precise fixture repeatability

• No third-party middleware required — the XI controller provides vision SDK integration out of the box

SZGH-1406-AW — Complete Welding Package

The AW variant ships with:

• SZGH-1406-A robot arm

Frequently Asked Questions

Q1: What makes the SZGH-1406-A different from a traditional long-reach welding robot?

A traditional long-reach industrial welding robot — such as the SZGH H or HZ series with equivalent reach — operates inside a full safety enclosure, requires a dedicated programmer for path changes, and is optimized for a single product running at high volume. The SZGH-1406-A is a collaborative long-reach robot: it works side-by-side with welders without fencing, any welder can teach a new weld path in under 20 minutes, and it switches between product variants with a button press. The key trade-off is that the H/HZ series runs at higher cycle speeds for fully automated, single-product cells; the 1406-A is optimized for multi-SKU production with human-in-the-loop quality oversight.

Q2: Why does IP65 matter specifically for aluminum welding?

Aluminum welding produces aluminum oxide particles that are finer and more abrasive than mild steel spatter. These particles penetrate unsealed robot housings and contaminate joint actuators and encoder systems within weeks of operation, leading to premature mechanical failure and calibration drift. The SZGH-1406-A's IP65 rating applies to the entire robot body — all six joints, all cable entry points, the base, and the wrist — preventing any particle ingress. For aluminum fabricators, this translates directly to elimination of the spatter-related maintenance events that are the most common cause of robot downtime in aluminum shops.

Q3: How quickly can a welder learn to program the SZGH-1406-A?

Welders with no prior robot or programming experience have recorded their first complete weld path in under 20 minutes using the 6-button drag teach handle. The physical motion is identical to hand-welding: guide the torch to the start point, record, move along the path, mark waypoints, save. For a door frame application with four perimeter seams, total teach time for a new frame SKU is typically 30–45 minutes including test runs and speed adjustment. Full production-ready proficiency across multiple SKUs is reached within three to five working days.

Q4: Can the SZGH-1406-A weld a 1,350 mm door frame in a single setup?

Yes. The 1,460.7 mm maximum armspan exceeds the 1,350 mm workpiece length with 110 mm of safety margin across the full reach. Paired with a rotary positioner (EtherCAT external axis), all four frame edges are welded in a single fixture setup — no repositioning, no splice point in the weld bead. This is the primary reason the SZGH-1406-A was specified for door and window frame applications: continuous bead, single fixture, zero repositioning joint.

Q5: Can the SZGH-1406-A operate without a safety cage around it?

Yes. The robot is certified for human-collaborative workcells under CE, CR, and NRTL standards, meeting the requirements of ISO/TS 15066 for human-robot collaboration. The 10-level adjustable collision detection stops the arm on human contact; the 100-point self-check verifies safety integrity before every power-on. The robot maintains safe stop even if the main cable is physically cut. A site-specific risk assessment is required per applicable local regulation, but a full enclosure is not required by the robot's design or certifications.

Q6: What is the XI Black Box and why is it important for a customer in Thailand or Vietnam?

The XI Black Box continuously records joint positions, motor currents, I/O states, and system logs to onboard non-volatile storage. When a fault occurs, the complete pre- and post-fault data record is exported to SZGH's remote support team via network. An engineer reviews the data and identifies the root cause — mechanical overload, external axis sync error, weld source fault — without traveling to the site. For customers in Southeast Asia where SZGH has a Thailand service agent but response times for on-site visits could be days, this means most faults are diagnosed and resolved remotely within the same business day.

Q7: Does the 260 W power rating mean the 1406-A needs special electrical infrastructure?

No. 260 W is the robot arm's rated power consumption, not including the welding power source. The robot arm itself runs on standard single-phase 220V AC — the same outlet used by most workshop equipment. The welding power source (included in the AW package) has its own power connection sized according to the welding process selected. No special electrical panel upgrade is required for the robot arm alone.

Q8: How does the SZGH-1406-A handle welding across multiple product variants (different frame sizes)?

Each weld program is saved as a named program on the XI controller. The operator selects the appropriate program from a simple list on the teach pendant — one button press, no code, no reprogramming. For a factory running 10 different frame SKUs, all 10 programs are stored and instantly switchable. When a new SKU is introduced, the drag teach process takes approximately 30–45 minutes to record and verify a new program. The ability to maintain a growing library of weld programs and switch between them in seconds is the primary productivity advantage over manual welding for mixed-batch production.
