Preparation
• Only experience, practice and care can guarantee a good
welding job.
• The factor intervening in the welding process are many:
required current, distance between the electrode and the
work piece, soldering speed and direction, thickness and
type of the material, the work piece position, electrode
angle and also gauge, type of material and electrode
covering. Therefore, is advisable that before welding to
carry out practice some in scrap material to determine
which are the specific requirements needed for the job to
perform.
• The area on the work piece where the soldering will be
applied shall be clean, free of rust and paint.
• Joints between sheets with gauges higher than 1/8" shall
be beveled to have an adequate weld (A).
Welding
• Set the switch (B) into the ON position.
• Adjust current control knob (C) until proper arc current
and intensity are achieved for the job. The current is
indicated on the panel display (D).
• Hold the electrode holder or torch as comfortable as
possible. Bear in mind that during the welding process, the
angle, movement and distance regarding the work piece
shall be constant and uniform.
• Aim the electrode tip to the joint to be worked with to
generate the arc and start welding.
• Once the arc is lit start soldering keeping always the
electrode tip 0.08" away from the work piece. If you make
the weld having the electrode supported on the work
piece, it could adhere and the weld would have a low
quality.
Slag Removal
• Upon finishing welding, use the wire brush included to
remove the slag from the weld bead surface.
CAUTION
• Wait until the slag has cooled down
and hardened to remove it.
• When hitting or brushing slag to remove it there can
be particles flying out. Wear eye protection and
keep bystanders away.

Electrode Replacement
• When the electrode has been consumed 0.4" to 0.8"
away from the electrode holder, it is necessary to replace it
with a new one to keep on welding.
• Electrodes are burned in high
CAUTION
temperature. Do not try to manipulate the remains of the
electrode with your hand. Set the remains in a metal
container.
• Open the electrode holder nipper to hold the new
electrode by the end that is not covered. Do not hold the
electrode by the covered part.
