Operating Mma - Jasic EVOLVE 200 Operator's Manual

OPERATION - MMA
Before starting any welding activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any persons within the welding
area.
MMA welding
MMA (Manual Metal Arc), SMAW (Shielded Metal Arc Welding)
or just Stick Welding. Stick welding is an arc welding process which
melts and joins metals by heating them with an arc between a
covered metal electrode and the work.
Shielding is obtained from the electrode outer coating,
often called flux. Filler metal is primarily obtained
from the electrode core.
The electrodes outer coating called flux assists in
creating the arc and provides a shielding gas and
on cooling forms a slag covering to protect the
weld from contamination.
When the electrode is moved along the work piece at the correct
speed the metal core deposits a uniformed layer called the
weld bead.
After connecting the welding leads as detailed above, plug your
machine into the mains supply and turn 'ON' the machine, the
power switch is located at the rear panel of the machine, place
it to the "ON" position, the panel indicator will then light up,
the fan may start to rotate as the welding machine powers up
and the control panel will also light up to indicate that the machine
is ready to use as shown below.
Caution, there is voltage output at both output terminals.
Please Note: The Evolve 200 is equipped with smart fan technology.
In the image above, you will note that MMA has been selected (circled red) and the
MMA current is also shown and is adjusted via the left control dial which is
previewed and set to 100amos as shown in the image above.
MMA Arc Force is also shown and is adjusted via the right control dial
and is previewed and set to 50% as shown above.
For remote control operation, which will allow the operator
to use a range of remote control accessories, see page 120
for further information.
When the power supply is first turned on after a short period
before welding starts, the fan will automatically start and then
stop. The fan will then run automatically when welding begins
or if the ambient temperature is too high.
Now you can connect the welding leads as shown
in the image right, ensure you check that you
have the electrode polarity correct to match
the welding rod being used.
