Electrode Replacement
SMAW:
• When the electrode has burned 0,4” to 0,7” from the
electrode holder, replace wit with a new one to be able to
keep on welding.
• The electrode burns in high
temperatures. Do not try to handle the electrode remains
with your hand. Put the remains in a metal container.
• Open the electrode holder tong to hold the uncovered
end of the new electrode. Do not hold the electrode in the
covered part.
TIG:
• Tungsten electrodes shall be sharpened to guarantee the
weld quality in a longitudinal direction.
• The tungsten electrode tip gets deformed due to the
heat. Therefore, when the tip is not showing an angle, it is
recommended to sharpen it again.
CAUTION
Preparation
• Only through experience, practice and care a good welding
process can be guaranteed.
• The factors arousing in the welding process are many: current
required, distance between the electrode and the work piece,
speed and direction of the welding, thickness and type of material,
position of the work piece and welding direction, and also, the
gauge, material and covering of the electrode. Thus, it is advisable
that before carrying out a weld, try to practice in scrap material to
determine which are the specific requirements for the job ahead.
• The area in the work pieces where the weld is to be applied shall
be clean, free of oxidation and paint.
• The joints between sheets with calibers larger than 1/8” shall be
beveled so the weld will be adequate (
A
).
Slag Removal
• Upon finishing the welding job, use a wire brush to
remove slag from the welding joint surface.
• Wait until the slag has cooled down
and hardened to be able to remove it.
• When hitting or brushing slag to remove it, there can
be particles shooting out. Wear eye protection and
keep bystanders away.
Arch Reinforcement
• During the weld process, generate an arch with enough
intensity, enough to burn the electrode constantly. If the
arch generated with the configured current (
C1
) is not
showing the intensity needed, use the “Arch
Reinforcement” knob (
C2
).
• Turn the reinforcement knob in a clockwise direction to
increase the welding arc intensity.
• If the arch is too intense, turn the knob in a
counterclockwise to decrease the ontensity.
The arch adjustment is very fine and delivers a
better control in the final aesthetics of the joint.
CAUTION
Welding
• Set the switch (
B
) in the ON position
I
.
• Adjust the current control adjustment (
C
1
), and the arch
enforcement (
C
2
) until reaching the adequate arch current and
intensity suitable for the job.
Current is indicated in the panel screen (
D
).
• Hold the electrode holder or torch in the most comfortable
position possible. Be aware that during the welding process, the
angle, movement and distance with regards to the work piece shall
be constant and uniform.
• Aim the electrode tip towards the joint to be welded to generate
the electric arch and be able to start welding.
• Once the arch is ON start welding, keeping always the electrode
tip 0,08” away from the work piece. If welding with the electrode
onto the work piece, it could stick and the weld would have a poor
quality.
• In the event of overheating, the welder will stop working and the
thermal protection indicating light (
E
) will be ON. Do not turn OFF
the welder. Wait for the indicator light turns OFF to use it again.
