—4-Step
1. To start the sequence, press the torch
thumb switch.
2. The welding current starts at the preset
starting current of 15 amps, and stays at
that level while the torch thumb switch is
depressed.
3. Gas flows for 0.5 seconds to purge the
torch line of air.
4. Release the torch thumb switch at any
time to raise the welding current to the
selected output current over the preset
upslope time of 0.2 seconds.
5. Press the thumb switch again to end the
welding operation.
6. The welding current decreases to the pre-
set finish current, and stays at the level
while the thumb switch is depressed.
7. Release the thumb switch at any time to
shut off the welding current.
8. The shielding gas continues to flow for
the post flow time selected.
General Welding
Operations
Becoming a good welder takes a lot of practice
and experience. If you are a novice, read books
and get help from an experienced welder before
beginning a welding operation.
Practice on scrap metal and expect to spend con-
siderable time learning the many aspects of good
welding.
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. Select the correct electrode, tungsten rod,
and filler metal type and size for your welding
project.
5. Choose the correct amperage output and be
aware of the duty cycle for this amperage.
6. Decide which type of weld is correct for your
project and properly prepare the metal.
7. Select the correct settings on the front control
panel for your welding operation.
8. Make sure all connections, hoses, gas cylin-
der, and grounds are correct and secure.
Note: Insert the welding cable connectors
into the welder output sockets and twist
clockwise until fully secure. For TIG welding,
connect the additional remote connector and
gas hose to the appropriate connections.
9. Stay aware of the work environment around
you as you weld, and ensure that flying
sparks do not start a fire.
10. Look slightly ahead of the arc. Even with
the protection of the welder's hood, looking
directly at the arc can damage your eyes.
11. Listen to the sound of the weld. Each type
of weld has its own distinct sound when it is
progressing correctly.
