EasyArc™ Laser Welding Cart
The EasyArc Laser Cart pairs the ABB GoFa™ collaborative robot with the THEO MA1 ULTRA handheld laser welder to deliver:
- Up to 5mm weld penetration
- 100% duty cycle
- Up to 10× faster welding than TIG
- Minimal heat distortion
- No post-weld grinding in many applications
No programming experience required.
Requires a laser-safe enclosure. Operators may remain in the room wearing appropriate laser safety PPE.
Laser Welding Configuration
Deeper Welds. Less Heat. Lower Costs.
Laser welding delivers deep, narrow welds with minimal heat input — resulting in a tiny heat-affected zone, virtually no distortion, and a clean bead that rarely needs post-weld grinding.
The EasyArc laser cart makes this precision process accessible to any operator. The same intuitive software that powers the MIG cart guides users through path teaching, material selection, and production launch — no laser optics knowledge or programming expertise required.
MWES stocks common components, making short lead times possible depending on configuration. Contact us to discuss availability for your specific requirements.

WHY LASER WELDING?
Up to 10× Faster Than TIG.
Laser welding isn’t just more precise — it’s dramatically faster and more efficient than conventional TIG and MIG arc welding processes.
| CONVENTIONAL TIG WELDING | EASYARC™ LASER (THEO MA1 ULTRA) |
|---|---|
| ✗ Slow travel speeds, especially on thicker materials | ✓ Up to 10× faster travel speeds than TIG |
| ✗ Significant thermal distortion on thinner gauges | ✓ Minimal heat input — very low thermal distortion |
| ✗ Wide heat-affected zone requires careful fixturing | ✓ Narrow heat-affected zone, precise energy delivery |
| ✗ Post-weld grinding and finishing often required | ✓ No post-weld process — clean welds off the cart |
| ✗ High skill level required for consistent quality | ✓ Any operator can run it with ~2 hours of training |
| ✗ Weeks of operator training required | ✓ Full production in ~2 hours of operator training |
| ✗ External water chiller required for duty cycle work | ✓ Air cooled — no external chiller needed |
| ✗ High energy consumption vs. laser | ✓ Up to 80% less energy than conventional arc welding |

| Material | Stainless, carbon, galvanized, aluminum |
| Thickness / Gauge | Select from predefined ranges |
| Weld Joint Type | Butt, lap, fillet, edge |
| Laser Power | Auto-configured; manually adjustable |
| Wobble Setting | 0–4mm, configured per application |
| Beam Tracking | Enabled / disabled per program step |

This system requires a laser-safe enclosure. MWES can supply the enclosure as part of the system order or advise on customer-supplied enclosure requirements. Operators may remain in the room during welding when wearing appropriate wavelength-rated laser safety eyewear. Customer is responsible for compliance with ANSI Z136 and applicable OSHA laser safety standards.
