WARNING: Power network earth connection
is not power network connection zero.
Connection between Welder and Electrode
Holder
Insert the quick connector of the welding cable
on the electrode holder into current output
“+” electrode adaptor on the second half of
the front panel and then screw down clock-
wise.
Connection between Welder and Work Piece
Insert the quick connector of earth cable with
earth clamp into current output “-” electrode
adaptor on the second half of the front panel
and then screw down clockwise. The earth
clamp is connected with work piece.
ATTENTION: Do not use steel plate or the
materials alike which are ill conductor to con-
nect between welder and work piece.
OPERATION INSTRUCTIONS
ATTENTION: The protection class of the se-
ries DC Inverter Arc Welder is IP21S. It is for-
bidden to put in a finger or insert a round bar
less than 12.5 mm (metal bar in particular) into
the welder. No heavy force can be employed
on the welder.
• The ‘protection indicator light’ will be on
after a long time operation, it shows that the
inner temperature is over the permitted data,
then the machine should be stopped using for
some time to let it cool down. It can continue
using after the ‘protection indicator light’ is
off.
• The power source should be switched off af-
ter the operation or while temporarily leaving
job site.
• Welders should dress canvas work cloth and
wear welding mask to prevent the hurt from
arc and thermal radiation.
• Light separating screen should be put in
the job site to prevent the arc will hurt other
people.
• Inflammable or explosive materials are pro-
hibited to access the job site.
• Each connection of the welder should be con-
nected correctly and creditably.
BASIC WELDING PROCEDURE
a) Connecting the power source switch, and
the Power Indicator will Light bright.
b) Regulate the welding current potentiom-
eter to reach the value for welding;
c) Take-up the torch hand, aim at the welding
seam, use the stick contact with the work piece
and then the electric arc was ignited, i.e. you
can effect the arc welding at the same time the
(welding Indicator Light) bright.
REPLACEMENT OF ELECTRODE
Only when the electrode burns up to 1~2 cm
away from the electrode holder does it be-
come necessary to replace it with a new one in
order to proceed with welding.
REMARKS: Electrode burns at high tem-
perature. Please do not use hand to replace it.
The replaced electrode end should be placed
in a metal container. Do not use the electrode
holder to clamp the electrode coating. While
ignite the electric arc, you should scrap lightly,
or it may adhere to the stick.
REMOVAL OF SLAG
When the welding job is finished, please use
the special slag hammer to knock off the slag
on the surface of welding rail.
REMARKS: Only until the slag cools off and
becomes hardened can the removal work
starts. To avoid the slag injuring people, never
point at the nearby people when you remove
slag.
MAINTENANCE & SERVICE
Unlike the traditional welder, the reversible
welder belongs to the scientifically sophisti-
cated product which uses the modern elec-
tronic component parts combined with state-
of-the art technology. Therefore the trained
personnel are required for its maintenance.
However, due to the fact that there are very
few components to be easily worn out, it
doesn’t need regular service apart from usual
cleaning work. Only the qualified people are
allowed to be in charge of the repair job. It
is strongly recommended that customers con-
