5.7 Setting the welding smoke flow rate
5.7.1 Measurement preparation
• Before measuring the flow rate, it is necessary to measure the amount of shielding gas.
• The quantity of shielding gas is measured at the gas nozzle of the welding torch and is set either di-
rectly on the pressure regulator or, if available, on the gas control unit of the wire feeder or power
source.
• Connect the welding torch to the welding machine or wire feeder.
• Connect the welding fume extractor hose to the welding torch using an adapter
> see 9 chapter
.
• Connect the welding fume extractor hose to the extraction system
The welding smoke flow rate can be influenced by using the bypass slider.
The illustration serves as an example only.
