Formier 10 as welding gas
Formier 10 is a hydrogen-nitrogen gas specially designed for the root protection of austenitic and high alloy stainless steels as well as non-alloy and low alloy steels in MIG, MAG, TIG and plasma arc welding.

Its 10% hydrogen content provides an effective reducing effect that removes oxygen from the root zone and allows an oxide-free, smooth and neatly formed root surface. The higher hydrogen content makes it more active than Formier 5 and makes it particularly suitable for demanding welding applications.

The reducing properties of hydrogen improve the corrosion resistance of the weld and reduce the gas purge times required prior to welding. The nitrogen content supports the properties of nitrogen alloy steels, reducing nitrogen loss and improving weld quality.

Formier 10 is a flammable gas and should not be used in tank welding to protect the root surface. The gas is also not recommended for welding ferritic, ferritic-austenitic or martensitic steels due to the risk of hydrogen embrittlement. Argon or pure nitrogen (duplex) is recommended for root protection.

Gases behave differently depending on their quality and state. Always consult the product’s safety data sheet before using the product. A safety data sheet is a document that conveys information about the properties, risks and safe use of a substance or mixture for industrial or professional use.

Risk of fire and explosion
Formier 10 is a mixture of hydrogen and nitrogen. Hydrogen is a highly flammable gas that burns hot with an almost invisible flame. A small amount of energy is required to ignite the hydrogen air mixture. Hydrogen under pressure may ignite when discharged without an obvious ignition source, e.g. static electricity or a hot surface. A hydrogen fire is always extinguished by shutting off the gas flow into the fire bag. Other extinguishing methods are dangerous because leaking hydrogen can easily re-ignite and the resulting gas cloud can create an explosion hazard. To prevent the fire from spreading, cool the area around the burning area with water if you can do so safely.

Choking hazard
An increase in the concentration of Formier mixed gas in the breathing air presents a choking hazard. Asphyxiation occurs unnoticed and can result in death.

First aid
A person suffering from oxygen deficiency must be immediately moved to fresh air. If the victim is having difficulty breathing or is not breathing, administer artificial respiration as quickly as possible and call for help. When rescuing a victim, it is important to remember not to enter an oxygen-deprived area without breathing equipment.

Unsuitable materials
Hydrogen can penetrate certain materials that are safe for use with other gases. Hydrogen may embrittle certain materials. Use only materials suitable for hydrogen.

Use of gas cylinders
– Follow the instructions and safe working practices when handling the substance
– The gas handler must be properly trained
– Use only carefully checked pressure regulators and other operating equipment suitable for this gas. If in doubt, contact Woikoske.
– Open the valve slowly to avoid pressure shock
– The valve is opened and closed by hand. The use of assistive devices is prohibited!
– It takes about one turn to open the bottle.
– The cylinder in use must be properly secured.
– Keep the valve outlets clean!
– Close the cylinder valve after each use and when the cylinder is empty.
– Always report damaged valves and cylinders to Woikoske.
– No smoking or open fires during use

Transport of gas cylinders
– The driver must be aware of the potential dangers of the load and know his duties in the event of accidents and incidents.
– Cylinders shall be transported in an upright position
– The load must be secured
– The protective hood on the cylinder valve must ALWAYS be in place during transport or even minor movement
– Cylinders must not be knocked, thrown or dropped from the truck platform
– Attention ADR regulations during transport

Storage of gas cylinders
– Observe all legal and local requirements for the storage of cylinders
– Take into account ATEX requirements
– Protect from heat, hot surfaces, sparks, open flames and other sources of ignition
– No smoking
– Do not store with oxidising substances
– Store cylinders in a well ventilated place
– Gas cylinders should not be stored in conditions which promote corrosion
– Gas cylinders are stored upright and secured so that they cannot fall over
– Valve caps of gas cylinders shall be in place during storage
– Empty and full cylinders should be kept separate
