Checking the flow rate. The shielding gas flow rates should not exceed 35 cfh.
To check the flow rate, press the PURGE button. The gas solenoid will open for 10
seconds, allowing you to check the flow rate and also clear unwanted gases from
the system.

AND INTERRUPTING THE WELD PROCESS
4.4.1 Starting to weld
To start welding, press the
WELD
button on the control box.
If stubbing occurs, raise the voltage until the process stabilizes.
After the first rotation, you should be able to view the placement of the weld bead
in relation to the previous bead and the base metal. As described in Section 4.2.2
on page 50, the correct step is attained when the weld is evenly placed between the
previous bead and base metal.
Normally, only adjustments to step, wire speed, and voltage are necessary to main-
tain the required weld deposits and feed necessary for successful borewelding.
WARNING
Use the appropriate light shield when making any visual inspection.
Avoid both direct and indirect exposure to arc rays.
