2. Select the appropriate electrode for the
material and process being performed. See
Table 5B: ELECTRODE SPECIFICATIONS
for selecting an electrode.
3. Place the ground clamp on the work piece
and insert the appropriate welding rod into
the electrode clamp.
4. On the control panel, place the CC/CV switch
in CC mode. Place the DC Charger/Welder
switch in welder mode.
5. Adjust the power dial to the appropriate
amperage setting for the material and the
electrode being used. (See Table 5B:
ELECTRODE SPECIFICATIONS for
electrode amperage ratings). At anytime
during welding, the power dial may be
adjusted to the desired amperage level.
For electrode striking technique, consult
Section A.7, Electrode Ignition Procedure
6. When you strike the electrode against the
material being welded, the motor will go to
full speed and deliver the selected amperage
through the electrode. Now you may begin
to weld.
7. After a weld has been completed, and there is
no contact between the electrode and the
metal for 30 seconds, the motor will return to
bypass.
