NOTICE
The following instructions are not intended
to be a complete list of welding steps. To
become a good welder, read books on weld
-
ing, get help from experienced welders, and
practice.
Although it is beyond the scope of this manual to
instruct how to weld, here are some general steps
for successful welding:
1. Read and understand this manual and ensure
that all safety instructions are followed.
2. Establish a safe and efficient welding envi-
ronment and ensure that you are properly
protected for the welding operation. Ensure
that there is a working fire extinguisher read
-
ily available.
3. Have an experienced welder stand by to
assist if needed.
4. Decide which type of weld is correct for your
project and properly prepare the metal.
5. Choose the correct amperage output and be
aware of the duty cycle for this amperage.
6. Select the correct electrode type and size for
your welding project.
7. Make sure the welding cables and grounds
are secure.
8. Stay aware of the work environment around
you as you weld and ensure that flying sparks
do not start a fire.
9. Look slightly ahead of the arc. Even with
the protection of the welder's hood, looking
directly at the arc can damage your eyes.
10. Listen to the sound of the weld. Each type
of weld has its own distinct sound when it is
progressing correctly.
