2. Spray the inside of the nozzle
and the outside of the contact
tip with anti-spatter spray.
3. Locate the torch over the joint
to be welded with the contact
tip approximately 3/8 inch from
the work surface.
NOTE
When welding steel, the ideal
position for holding the torch
is inclined approximately 30
degrees towards the direction
of travel. This allows the arc
to be seen easily, resulting
in greater control of the weld
pool. Most right-handed wel-
dors move from left to right.
This method, known as fore-
hand welding, provides a gas
shield for the cooling weld
puddle and helps in obtaining
an oxidation free weld de-
posit.
4. Use a welding helmet with a
shade 9 to 11 filter lens,
depending on operator prefer-
ence.
5. Squeeze the torch trigger. The
wire will feed and an arc will
be established. As the weld is
deposited, move the torch slowly
along the weld seam at a con-
stant speed, maintaining a con-
stant arc length and a constant
tip-to-work distance.
