WELDER STRUCTURE
The SOT-225 a.c. stick welder is made with an iron core converter.
The primary and secondary winding is divided in two parts, coiled
separately in the iron core of the converter and it applies with the
shunt as a magnetic leak. The current adjustment is obtained moving
the shunt: when the shunt moves in the static shunt, the reactance
value of the leak reaches it maximum point, while the current value
is reduced to the minimum and vice versa. The shunt backwards
movement is achieved adjusting the wire so the current and be
gradually adjusted as well as achieving the solid current linearity.
WARNING! The 220 V
not be connected in an incorrect manner, otherwise, the
converter will burn or the welder will not wonk.

Welder Standards
The SOT-100 stick welder is in compliance with the EN50060
International Standard, part 9, Technical Conditions of the Welder
under limited working service.
INSTALLATION
The SOT-225 a.c. - stick welder housing protection grade is IP21S.
It is not allowed to introduce the fingers or insert a round bar smaller
than 12 mm (especially metal bars) into the welder.
WARNING: The welding current sources are not suitable
for use under rain or snow.
When using the welder, it needs an adequate input
current. If the capacity of the electric network is enough,
it has an in uence in the power supply network. If you
have any doubt, please consult the experts.
WELDER CONNECTION INTO THE POWER SUPPLY
When connecting the welder into the power supply always double
check the voltage complies with what is indicated in the welder
nameplate.

CONNECTION BETWEEN THE WELDER, THE ELECTRODE HOLDER
AND THE WORK PIECE
One end of the welding output cable connects to the welder as shown
in the panel, the other end connects to the work piece and to the
electrode holder.
If the welder output cable if has fast-connection, the connection
screws shall be adjusted and secured, otherwise, the fast connection
and the welding cable may be damaged.
