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.

Stick Welding (MMAW)
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.
