Product details

Weldmix 2% CO₂ gas cylinder, filled with 50L of AR CO₂, specially developed for welding stainless steel (designed for long-term and professional use).

Transport & Use:

  • Mechanical transport: Due to the weight (approx. 60–80 kg depending on filling pressure), manual lifting is prohibited. Always use a mechanical aid when loading and unloading.
  • Fixation: For transport in a vehicle, securing with certified ratchet straps at two heights is mandatory to prevent tipping.
  • ADR regulations: For commercial transport, the B50 is subject to ADR guidelines (UN 1956, Compressed gas, n.o.s., 2.2). Ensure you have the correct documentation and safety equipment.

Specific safety information for Weldmix 2% (B50):

  • Asphyxiation hazard: With a large B50 cylinder, the risk of oxygen displacement in the event of a leak is real, especially in confined spaces. Always ensure active ventilation or source extraction in the welding workshop.
  • High-pressure system: Working with 200 or 300 bar requires an industrial-grade pressure regulator/flow meter. Regularly check that the seals on the connections are in good condition.
  • Mechanical safety: A full B50 is heavy and has a high center of gravity. For internal transport, always use a robust cylinder trolley with a chain restraint.
  • Valve protection: The B50 is long; the valve is extremely vulnerable if the cylinder tips over. Always keep the protective cap on when the cylinder is not in use or is being transported.
