Submerged Arc
Product and Procedure Selection
With disconnected LN-8 or LN-9 wire feeders, set the inch speed for the
slow rate. If the arc flutters on and off, increase the inch speed. If inch
speed is too fast, the wire will tend to stick on starting.
Position the gun over the joint as described under “Gun Operating
Positions”. Allow the mound of flux to form. Press the trigger and touch
the electrode to the work by lightly scratching through the flux.
If the electrode hits the work, pushing the gun up without starting the
arc, immediately release the trigger, raise the gun, and turn the nozzle
up. Be sure the work lead makes a good connection and the work is
clean at the starting point. Clip the electrode end and try again.
