9. MMA WELDING
To select this welding mode, use switch 10,
select MMA and press confirm.
Electric arc welding with a covered MMA
(Metal Manual Arc) electrode or SMAW
(Shielded Metal Arc Welding) is a manual
welding procedure that takes advantage of
the heat generated by the electric arc, which
strikes between a covered earthed electrode
and the workpiece. This procedure allows for
the creation of joints in any position, in the
workshop, outdoors, in confined areas or
places that are difficult to access.
With the TM 236 it is possible to weld any
type of electrode and diameter. The spark of
the arc occurs by placing the electrode close
to the workpiece.
The correct connection of the electrode
clamp holder and the earth cable can be
seen in the table below:
Always make sure that the earth and the
electrode clamp holder are kept far apart.
9.1 MMA WELDING Manual
This mode can be accessed using switch 10.
Selecting this option will take you to the
welding screen:
Switch 9 in fig. 1 adjusts the welding current
(very thick workpieces require a higher
current).
Furthermore, switch 10 adjusts the
parameters shown in the figure below:
ADJUSTMENTS AND SETTINGS:
Button 10 adjusts the welding settings on the
screen:
Arc Force:
Used to set the increase in current
as a percentage of
the welding current, which the welder can
provide to keep the arc fully ignited.
Hot start:
Used to set the current increase as
a percentage of the welding current, which the
welder can provide at the time the arc is struck.
Hot start span:
Used to set the time during
which the hot start current is provided.
Remote ctrl:
Used to switch on (ON) or switch
off (OFF) the remote control of the intensity of
the current delivered.
