1. Press (and hold) Trigger and contact area to
be welded with electrode wire to ignite arc.
2. For a narrow weld, you can usually draw the wire in
a steady straight line,
this is called a stringer bead.
For a wider weld, draw the wire back and forth
across the joint, this is called a weave bead.
3. Hold Gun in one hand and the face shield in the
other. If a hands-free welding shield (not included,
see Arc Ray Safety on page 3 for guidelines) is
used, then both hands can be used to control Gun.
4. Direct the welding wire straight into the joint.
This gives an angle of 90° (straight up and
down) for butt (end to end) welds, and an
angle of 45° for fillet (T-shaped) welds.
5. The end of Gun should be tilted so that wire
is angled anywhere in-between straight on
and 15° in the direction you are welding. The
amount of tilt is called the drag angle.
6. The welding wire should extend no more than
1
/
2
past the tip.
This distance is called stickout or CTWD
