SL3 UNI
Universal 3-Head CNC Welder for Complex Angles and Crossbars
Maximum versatility for custom productions
Perfect if:
- Weld multiple components at the same time (corners + crosspieces)
- Manage complex configurations with a single machine.
- Achieve high-precision welds on white, coloured, or coated profiles.
- Work on angles from 35° to 180° as well.
- Optimize cycle time with dual unit mode.

Maximum versatility for custom productions
The SL3 UNI is the most versatile 3-head CNC welder in the Graf Synergy range. Designed to tackle any construction combination, it allows for the simultaneous welding of 90° angles, ‘T’ joints, cross joints, ‘H’ joints, and variable angles from 35° to 180°, even in combination with each other.
In just two cycles, you can create a complete window with a central crossbar. The three heads work in line, and two of them can rotate 90° to simultaneously weld both ends of a crossbar.
5 Reasons to Choose SL3 UNI
- Absolute Versatility. Unique in handling 90° welds, ‘T’ joints, crosses, ‘H’ shapes, and variable angles with the same heads.
- Dual mode. Usable as two separate welders: one single-head and one double-head.
- Advanced electronic control. Precise management of plate temperatures and edge limiter knives.
- Quick Change Contour Plates. Fast attachment/detachment system to minimise setup time.
- Maximum stability and aesthetic quality. Solid construction, continuous welding, and curb adjustment between 0.2 and 2 mm to meet every aesthetic requirement.

Technology and Automation
SL3 UNI is designed for high flexibility lines and special processing. The three heads, which can also be configured separately, allow for the creation of complex frames without the need for multiple machines.
The centralised electronic control allows for precise management of temperature, edging, and operational sequences. The user interface and the quick-change contour system make the SL3 UNI ideal for those who need to handle many construction variants in a short amount of time.
