Gun Position
For “down hand” fillet welding with gas
shielded solid wires, the gun is normally
positioned as shown in Figure 7a below, with
the nozzle end pointing in the direction of
travel.
For “down hand” fillet welding with
gasless flux cored wires, the gun is normally
positioned as shown in Figure 7b, with the
nozzle end pointing away from the direction
of travel, referred to as ‘dragging’ the weld.
Gasless flux cored wires should be operated
with approximately 10-15mm of wire ‘stick-
out’ from the welding contact tip as shown
in Figure 7c.

Connection for Stick Welding
It is important to select the electrode polarity
in accordance with the manufacturers
recommendations for that electrode. Most
common electrodes, including cellulose
types, are operated with the electrode at
positive polarity, as illustrated in Figure 8.
