the tension is enough.
Setup Guide
Getting Started
TRIM THE WIRE AFTER INSTALLATION.
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 beginning a new weld if the wire is not already trimmed
to this length. This will help to improve arc restarts.
PROPERLY TENSION THE WIRE FEEDER.
To feed properly, the wire needs to be tensioned before you begin
welding. The tensioning lever has numbers on the dial. To increase
tension, rotate the tension lever clock

wise. Different types of wires
require different tensions. There is no exact tension that works for all
wire types. However, 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 ten-
sion 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.
