6. Hold the Gun, without touching the
Trigger, with the wire and tip clearly out of
the way of any grounded objects.
Then, turn the Power Switch ON.
Basic Welding technique
Press (and hold) Trigger and contact area 1.
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.
Hold Gun in one hand and the face shield 3.
in the other. If a hands-free welding
shield (not included, see #6, page 4 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.
The welding wire should extend no more 6.
