Trim the wire sticking out of the nozzle to
1/4”
to
3/8”
(6mm to 9mm) in
length with wire cutters. See the illustration below. The gun is now ready
for welding
. Hint: Always make sure that you re

trim the wire before be-
ginning a new weld if the wire is not already trimmed to this length. This
will help to improve arc restarts.
Tensioning the Drive Roll Pressure
To feed properly, the wire needs to be tensioned before you begin weld-
ing. The tensioning lever has numbers on the dial. To increase tension,

wise. Different types of wires require differ-
ent tensions. There is no exact tension that works for all wire types. How-
ever, for steel wire, you will generally tension to at least 4 on the dial. For
flux
-
cored wire, it may be only two or three. Wire diameter also plays a
small part in the amount of required tension that is needed. Regardless of
the wire type or wire diameter, follow the process below and refer to the
following illustration. Turn the unit on and pull the trigger so that the wire
extends approximately
1”
beyond the gas nozzle.
•
Find a small block of wood, such as a two by four, and secure it to
the welding table or other solid object. Do not test this on metal!
•
Hold the gun approximately 2 inches off the wood. Aim the gun at the
block of wood so that the nozzle is at a 30 degree angle to the wood.
•
Pull the trigger and allow the wire to contact the block.
•
Increase wire tension so that the wire contacts the block of wood and
is forced to curl up. Continue holding the trigger so that two or three
full spirals are made.
•
If the wire stops, or stutters during this process, let go of the trigger
immediately and increase tension.
•
Adjust the wire until the stuttering or jerking disappears.
•
Do not over
-
tighten the tensioner or use more tension than neces-
sary. When the wire begins to curl without any stoppage, the tension
is enough.
