Technical Specs
Note: Feet and inch dimensions are approximate conversions from the metric system. Power cable and air supply are required but not included.
Rear guide: To do pockets and to fix guides.
Secure pneumatic control valve: In compliance with current machine safety regulations, all power supplies—both electrical and pneumatic—must be cut off when an emergency stop (E-STOP) or other safety element is activated. The machine is equipped with a safe pneumatic control valve that ensures this function is carried out reliably.
Quick-change welder system: Access for making the change is easy. A clamp system also simplifies the process. A specific procedure must be followed, which is explained in the manual. The change requires two people with maintenance experience, some tools, and adjustments and tests after completion.
Flexible welder range: For working with different welders widths it is not necessary to change the transformer (this could change a little the effective welding power (Kw/cm^2)).
Built for Safety & Compliance: Forsstrom machines adhere to CE safety standards, ensuring reliability and operator protection.
*Motorized pocket positioning enables precise fabric adjustments with electronic offsets.
**The electronic pressure control system automatically adjusts machine pressure during the welding cycle and provides real-time pressure data.
