Ensure the gas cylinder is turned on and the flow-meter or regulator is set to give approximately 15
to 20 Litres per minute. (30 to 40 cubic feet per hour).
8. Welding power in connector
Until you are familiar with the machine it is preferable to start welding on a piece of waste material

To provide welding power and voltage to the feed unit
the same type and thickness as the work-piece, adjust the voltage control (if fitted), wire feed and
gas flow until the required welding condition is achieved.
When used with the Newarc power sources all the controls can be adjusted whilst welding without dam-
aging the machine.
