.
4.3 Safety checks before welding commences
Make sure that the propane gas cylinder is sufficiently filled to carry out the preheating correctly, which takes about
eight minutes (variable depending on the nature of the weld) under a gas pressure of 1 bar, i.e. a minimum quantity
of gas of 1 kg to maintain correct propane vaporization and therefore correct preheating.
The use of scales or equivalent can be used to find out the amount of gas remaining in the cylinder.
With the HFP and its connection hose in its transport and storage case, carefully remove the HFP.
