**Which Robotic Welding Cell Is Right for My Parts?
The 2026 Motofil Selection Guide (U.S. Edition)** Match your weldment size, weight, and production needs to the right pre‑engineered system.
The Short Answer
Choosing the right robotic welding cell comes down to three numbers:
- Weight (250 kg → 2000 kg)
- Length (1.0 m → 6.0 m)
- Diameter (0.8 m → 1.8 m)
Once you know your part envelope, the right Motofil system becomes obvious.
This guide shows you exactly which system fits your parts — and how to get a quote fast.
Why This Guide Matters
Most U.S. manufacturers don’t know Motofil yet — but they do know their parts.
This guide flips the buying process:
Instead of choosing a system → you start with your parts.
That’s how you eliminate guesswork, reduce risk, and get a system that welds correctly on day one.
The Motofil x KC Robotics Lineup at a Glance
Motofil offers nine pre‑engineered welding platforms, each designed around specific part sizes, weights, and production styles.
Here’s the simplified map:
| System | Weight | Length | Diameter | Stations | Starting Price |
|---|---|---|---|---|---|
| Cobot (3′ x 4′) | 250 kg | 1.2 m | 1.0 m | Single | $115k |
| Butterfly (HS / Skyhook) | 250 kg | 1.0 m | 0.8 m | Dual | $245k–$295k |
| Double Skyhook (Gantry) | 1000 kg | 1.0 m | 1.8 m | Dual | $385k |
| H‑Table HT1 / HT2 | 600–1000 kg | 2.0–2.8 m | 1.2 m | Single | $265k–$385k |
| Monoblock (Back‑to‑Back) | 2000 kg | 3.0 m | 1.4 m | Dual | $285k |
| Monoblock Inline (Side‑by‑Side) | 2000 kg | 3.0 m | 1.4 m | Dual | $375k |
| M‑Lean (Ferris Wheel) | 1000 kg | 6.0 m | 1.4 m | Single | $365k |
These numbers come directly from your buyers guide.
Step 1 — Identify Your Part Envelope
Before choosing a system, answer three questions:
- What is the heaviest part + fixture weight?
- What is the longest part you weld?
- What is the largest diameter or width?
Once you know these, the system selection becomes automatic.
Step 2 — Match Your Parts to the Right System
If your parts are under 250 kg
Choose:
- Cobot (single station)
- Butterfly (dual station)
Best for:
- Brackets
- Small frames
- Light fabrication
- Job shops
Why:
- Fastest install (1 day)
- Lowest cost
- Perfect for high‑mix, low‑volume
If your parts are 250–600 kg
Choose:
- H‑Table HT1
Best for:
- Medium weldments
- Agricultural components
- Structural subassemblies
Why:
- Single‑station load/unload
- 2.0 m length capacity
- 600 kg weight limit
If your parts are 600–1000 kg
Choose:
- H‑Table HT2
- Double Skyhook
- M‑Lean (if long)
Best for:
- Large frames
- Heavy plate weldments
- Multi‑axis access needs
Why:
- HT2 adds dual robots
- Double Skyhook gives 5‑side access
- M‑Lean handles long beams up to 6.0 m
If your parts are 1000–2000 kg
Choose:
- Monoblock (Back‑to‑Back)
- Monoblock Inline (Side‑by‑Side)
Best for:
- Large structural assemblies
- Trailer components
- Heavy OEM parts
Why:
- 2000 kg capacity
- Dual stations for continuous production
- 3.0 m length capacity
If your parts are long (4–6 meters)
Choose:
- M‑Lean
Best for:
- Long beams
- Chassis rails
- Structural members
Why:
- 6.0 m length capacity
- 1000 kg weight
- Ferris‑wheel gantry for ergonomic loading
Step 3 — Choose Your Production Style
High‑mix, low‑volume
- Cobot
- Butterfly
- H‑Table HT1
Medium‑volume, repeatable production
- H‑Table HT2
- Monoblock
- Monoblock Inline
Large, heavy, or long weldments
- Double Skyhook
- M‑Lean
This is where Motofil shines — standardized systems that fit real‑world production patterns.
Step 4 — Consider Your Weld Access Needs
Need 4‑side access?
- HS/TS systems (Butterfly, Monoblock)
Need 5‑side access?
- Skyhook systems (Double Skyhook)
Need maximum reach?
- M‑Lean
- Double Skyhook
This is where Motofil’s mechanical engineering gives you a real advantage.
Step 5 — Understand What’s Included (This Is a Big Deal)
Every Motofil system includes:
- Touch sense
- Through‑arc seam tracking
- Tooling picture frames
- FANUC ArcTool
- Motofil iWeld Light HMI
- Coordinated motion
- Auto error recovery
- Dual‑Check Safety
- Torch cleaning station
- Choice of welding package (Miller, Lincoln, ESAB, Fronius)
Plus:
- Lifetime operator/programmer training
- On‑site installation & startup
- Certified A3/RIA safety risk assessment
This is why Motofil systems install in 1–3 days — everything is standardized.
