It is compatible with common base materials such as carbon steel and stainless steel.
Q Is the welding robot difficult to operate? Can workers with no experience master it quickly? +
A
The system uses a visual touch-screen interface and includes
100+ built-in general welding parameter templates.
With 5–7 days of on-site hands-on training, even workers with zero experience can operate independently.
We also support remote online guidance and debugging.

Q What are the working range and payload of different welding robot models? +
A
Our main model uses a 6-axis heavy-duty robotic arm with a
8 kg payload and a 2,032 mm working radius.
Extended-arm versions can be customized to match different workpiece welding requirements.

2) Technical Parameters & Application (Key for Technical Selection)
Q What is the welding accuracy, and what working scenarios is it suitable for? +
A
Repeat positioning accuracy: ±0.03 mm.
Welding penetration deviation: ≤ 0.1 mm.
It adapts well to non-standard large workpieces such as steel structures, tanks, boxes, special-shaped parts, and ultra-high / oversized workpieces.
It’s also suitable for demanding environments including outdoor, high-temperature, and toxic gas working areas.

Q What are the main differences between the M1 Pro and ML1 welding robots? +
A
The key difference is the driving mode: M1 Pro (wheeled) vs ML1 (tracked).
ML1: turning radius 1.1 m, welding height 3.27 m — better for narrow spaces and rough road conditions.
M1 Pro: equipped with an automatic lifting device, turning radius 4.8 m, max lifting welding height 3.725 m — better for high-altitude welding in open spaces.
Both have a max horizontal welding width of 3.85–4.012 m. An 8 m horizontal weld typically requires 1–2 position movements.

Q Can the welding robot work stably in harsh environments such as high temperature or dusty workshops? +
A
The body is treated to be dust-proof, oil-proof, and
high-temperature resistant.
It can operate reliably in industrial environments with temperatures from -10℃ to 45℃ and dust concentration ≤ 10 mg/m³, including outdoor closed welding stations.

3) Operation & Cost Questions (Key for Purchase Decision)
Q Is it easy to replace consumables? What are the daily maintenance costs? +
A
Consumables such as welding torches, contact tips, and
wire feed tubes are universal standard parts, and we provide
step-by-step video guides.
Replacement is quick and straightforward—no professional engineers required.
Daily maintenance mainly includes nozzle cleaning and adding antifreeze. The average monthly maintenance cost is about USD 150–200.

Q How many manual welders can one robot replace? What is the typical payback period? +
A
One unit typically replaces 2–4 skilled welders and supports
24/7 continuous operation.
With a reference monthly welder salary of USD 2,500, the payback period is usually 12–18 months.
For large non-standard workpieces, it can be shortened to about 12 months.

Q What is the wire consumption per hour? Deposition rate: 4–5 kg/h (for GMAW/FCAW) +
A
In heavy-duty thick-plate and hardfacing applications, using
1.2 mm solid wire with water-cooled automatic welding, wire consumption is
4–5 kg per hour, compared with about 1.5 kg/h for manual welding.
The robot can run continuously for 24 hours, while manual work is typically < 8 hours/day, so the efficiency advantage is especially clear in high-intensity, repetitive, and high-temperature environments.
For long straight welds: 8–20 meters/hour.
For circular welds on 6 mm chemical tanks (1.6–1.8 m diameter): welding speed ≈ 20 cm / 5 min, i.e. 1 m / 30 min.
