Smart manifolds for welding-type systems
Systems and apparatus are disclosed relating to smart regulators and smart manifolds for welding-type systems. A smart regulator may be coupled to a fluid tank and provide information regarding the current pressure(s) and/or flow rate to a remote device and/or operator. The remote device may also determine and/or output additional information, such as, for example, remaining fluid and/or remaining time before the fluid runs out or becomes dangerously low. A smart manifold may be configured to work with several different fluid supplies. In this way, an operator may easily mix fluid types, switch between different fluid types, and/or switch between different fluid tanks.
