1.
Basic Wire Welding Technique
Press (and hold) Trigger and contact the 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
and takes
practice to perform properly.
3. 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.
4. For MIG welding using solid wire and
shielding gas, the end of the MIG Gun should
be tilted so that wire is angled anywhere
in-between straight on and 15° away
from the direction you are welding. The
amount of tilt is called the
push angle
.
5. When using flux-cored wire without
shielding gas, the end of the MIG 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 Contact Tip should remain within 1/2″
of the work surface. This distance is called
CTWD
- Contact Tip to Work Distance.
