SZGH HZ2000-B-6 Enhanced-Generation 6-Axis Arc Welding Robot

What Is the SZGH HZ2000-B-6?

The SZGH HZ2000-B-6 is an enhanced-generation 6-axis industrial arc welding robot delivering a 2,000 mm reach and 6 kg payload, combining the HZ series' reinforced fully enclosed axis architecture with a medium-heavy 170 kg frame — purpose-designed to bridge the gap between the H1500-B-6 and H2100-B-6, providing extended reach for large workpieces while delivering HZ-grade spatter protection for continuous MIG, MAG, TIG, and plasma arc welding in furniture, agricultural machinery, and medium structural fabrication environments.

Complete Technical Specifications

Note on ±0.08 mm Repeatability: Arc welding produces seam widths of 3–8 mm. At ±0.08 mm, the HZ2000-B-6's torch tip repeats position within a 0.16 mm band — far tighter than the weld bead. The HZ series upgrade is concentrated on protective sealing and structural rigidity, not precision, which already exceeds arc welding requirements by a wide margin in both H and HZ series robots.

Core Advantages — Why HZ2000-B-6?

2,000 mm Reach — The Optimal Gap-Filler Between H1500 and H2100

The H series presents buyers needing more than 1,500 mm reach with a single option: the H2100-B-6 at 2,100 mm and ~235 kg. For many applications — furniture frames, agricultural implements, medium structural fabrication — 2,100 mm is more reach than required, and the H2100's 235 kg platform adds unnecessary mass and floor footprint. The HZ2000-B-6's 2,000 mm reach on a 170 kg frame fills this gap precisely: more reach than the H1500, meaningfully lighter than the H2100, and with HZ-grade enhanced protection built in. It is not a compromise — it is a purpose-built model for medium-large workpiece welding.

Reinforced Fully Enclosed Axis — HZ Series Core Upgrade

All six axes are sealed to the HZ enhanced standard, validated for high-spatter MIG and MAG welding environments. Agricultural machinery welding generates continuous metallic spatter from thick-plate (6–14 mm) joints. Furniture metalwork involves fine steel and alloy tubing that generates fine particulate. Both environments challenge conventional robot sealing over extended production runs. The HZ2000-B-6's joint protection prevents spatter and metallic dust ingress into cable bundles and encoder housings — eliminating the primary failure mode seen in general-purpose robots after 9–12 months of multi-shift operation.

Structural Optimisation — Improved Rigidity at Extended Reach

At 2,000 mm reach, the lever arm from axis 1 to the torch tip is substantially longer than on a 1,500 mm robot. The HZ2000-B-6 incorporates the HZ series structural enhancements — refined body rigidity and joint transmission geometry — to maintain consistent torch tip stability across the full working envelope. This is particularly relevant for long continuous weld passes (1,000+ mm) on agricultural implements and structural steel sections, where torch deviation over distance directly affects bead consistency.

Multi-Process, Multi-Material Coverage

The HZ2000-B-6 handles the full arc welding process spectrum: MIG for general structural steel, MAG for high-speed structural fabrication, TIG for stainless steel precision joints, and plasma arc for specialist applications. For factories producing mixed product lines — some items requiring MIG, others TIG — a single HZ2000-B-6 with process-switchable programming handles all variants without robot changeover.

Program-Based Quick Changeover — From "Train a Welder" to "Press a Button"

The SZGH GH2000-B controller stores 500+ welding programs. For manufacturers producing multiple product variants — a common situation in agricultural component shops — each part program stores all path, arc, and weave parameters. Switching between product variants requires selecting a program on the teach pendant. No re-teaching, no parameter re-entry. For one of our Mexican agricultural clients, this reduced product changeover from a two-week new-welder training cycle to a single button press.

Application Scenarios

H Series vs. HZ Series — Model Selection Guide

How to choose: The HZ2000-B-6 occupies a distinct position: extended reach with enhanced HZ protection, at a frame weight between the H1500 and H2100. Use this table to map your workpiece size and environment to the right model.

Selection logic:

• Workpieces up to 1,500 mm, standard production: → H1500-B-6

• Workpieces up to 1,500 mm, heavy-spatter / three-shift: → HZ1500-B-6

• Workpieces 1,500–2,000 mm, any spatter level: → HZ2000-B-6 (the only HZ/H option in this reach range with enhanced protection)

• Workpieces requiring 2,100 mm reach, standard environment: → H2100-B-6

• Heavy structural welding, maximum reach: → H2100-B-6

Customer Case Study — Fannie Chen, CEO

By Fannie Chen, CEO, Shenzhen Guanhong Automation Co., Ltd. (SZGH) | May 2026

A manufacturing client contacted us from Mexico — a producer of agricultural equipment components, primarily plough share seats and seeder brackets. Their materials are 6–12 mm structural steel plate, welded with MIG at moderate to high current settings. A single finished component carries 1,200–1,600 mm of total weld seam length, and their largest workpieces reach 1,700 mm in overall length.

Their constraint was straightforward: a limited floor footprint, a mixed product range spanning roughly 15 part variants, and a maximum workpiece dimension of 1,700 mm that exceeded what the H1500-B-6 could comfortably cover. The H2100-B-6 would have been more machine than they needed — larger footprint, heavier frame, higher per-unit cost for reach they would never use.

The HZ2000-B-6 was the exact answer. Its 2,000 mm reach covers their 1,700 mm workpieces with margin. The HZ protection handles the continuous MIG spatter from thick-plate agricultural components without the seal degradation their previous domestic robot had experienced. And the SZGH controller's 500-program storage meant that all 15 part variants could be pre-programmed and stored — operators switch between products by selecting a program number on the pendant.

The client's observation, shared six months after installation: what previously required training a new manual welder over two weeks to handle a product changeover now takes pressing one button. Consistency across variants improved, rework dropped, and the robot has maintained seal integrity through continuous production without a single mechanical issue.

That is the combination the HZ2000-B-6 is built for: the right reach, the right protection, and a control system that handles production variety without friction.

Frequently Asked Questions

Q1: What makes the SZGH HZ2000-B-6 different from the H2100-B-6?

The HZ2000-B-6 is the enhanced-generation HZ series model with 2,000 mm reach, versus the H2100-B-6's 2,100 mm reach. The HZ2000-B-6 upgrades axis sealing to the HZ enhanced standard, validated for heavy-spatter and three-shift continuous welding. It also weighs ~170 kg versus the H2100-B-6's ~235 kg, making it more suitable for medium-duty structural applications where the H2100's reach and mass are more than required. The HZ2000-B-6 is the right choice when you need more than 1,500 mm reach and want HZ-grade protection; the H2100-B-6 is preferred when 2,100 mm reach is a hard requirement.

Q2: Can the HZ2000-B-6 weld workpieces up to 2,000 mm?

Yes. The 2,000 mm figure is the maximum reach radius from the robot's base axis. For elongated workpieces, the robot is typically positioned alongside the workpiece with a positioner rotating the component through the weld path. In coordinated motion with a positioner, the effective welding coverage exceeds the reach radius. For the 1,700 mm agricultural components in our Mexico case study, the robot covers the full weld seam length with margin.

Q3: Is the HZ2000-B-6 suitable for furniture manufacturing welding?

Yes. Steel and iron furniture frame welding — gates, railings, frame chairs, shelving systems — involves repetitive short-to-medium weld seams on thin-to-medium tube and flat section. The HZ2000-B-6's 2,000 mm reach covers large furniture frame assemblies without repositioning. The multi-program storage handles the high product variety typical in furniture shops, and the HZ protection manages the fine metallic particulate environment generated by thin-section furniture welding.

Q4: What welding processes does the HZ2000-B-6 support?

The HZ2000-B-6 supports MIG, TIG, MAG, and plasma arc welding. For agricultural and furniture applications, MIG is the primary process. The same robot can handle stainless steel TIG precision welding and aluminium alloy welding when required, with process parameters stored as separate programs per part.

Q5: How does the SZGH controller handle product changeovers?

The SZGH GH2000-B controller stores 500+ part programs. Each program contains the complete welding path, arc parameters (voltage, wire feed speed, travel speed), weave settings, and positioner coordination data. Switching between part variants requires selecting the program number on the 7-inch touchscreen pendant — no re-teaching, no parameter input. For factories with 10–20 product variants, all programs can be pre-loaded and recalled instantly.

Q6: Can the HZ2000-B-6 operate in three-shift continuous production?

Yes. The HZ series, including the HZ2000-B-6, is validated for three-shift (24 hours/day) continuous operation. The reinforced joint sealing and enhanced thermal management inside each axis are designed for sustained duty cycles. Recommended maintenance intervals (lubrication, seal inspection) are detailed in the supplied maintenance manual and supported remotely via SZGH WhatsApp technical assistance.

Q7: What positioner is recommended with the HZ2000-B-6?

For agricultural components with compound weld seams, the SZGH dual-axis positioner (BWJ 2-axis series) is recommended, enabling full coordinated tilting and rotating of workpieces up to the positioner's rated load. For simpler rotational seams (pipes, flanges, tubular frames), the single-axis BWJ positioner is sufficient. Both integrate as external axes in the GH2000-B controller with full coordinated motion programming.

Q8: What is the delivery lead time and how do I get a quotation?

Standard lead time is 30–45 working days from confirmed purchase order and deposit. For quotation, contact our export team at export02@szghtech.com or via WhatsApp at +8618925223781.
