The air supply to the weld station must be dry or drained. Water carried with air into the Weldstation can wash away lubricating oil. This can mean excessive wear to pneumatic components and higher maintenance expenses. Without adequate lubrication pneumatic components can run sluggishly and inefficiently be prone to air leakage. Water in the supply line must be removed using a dryer or water drain trap.

Each unit must be fitted with a shut off valve capable of being locked out with blow off capability. Safety procedures such as lock out / tag out procedures must be followed with pneumatic as well as electrical systems. This means, the valve must be a 2-way valve which will exhaust the air from the Weldstation when the shut off valve has been locked out. The exhaust port should be fitted with a pneumatic muffler to reduce noise if above unacceptable levels.
