OPERATION (see the front panel)
• When using flux wire, the gear type groove wire roller
should be used.
b) Welding
• When welding, please adjust the welding current and
welding voltage matchable according to the set-up
• Aim at the welding line, press down the torch switch,
the wire feeds automatically. The arc is started once
the wire is touched the work piece. When welding,
the "working indicator" is on
MAINTENANCE AND SERVICE
Unlike the traditional welder, the reversible welder belongs to
the scientifically sophisticated product which uses
the modern electronic component parts combined with high
technology. Therefore the trained personnels 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
contact our company for the technical back-up or
service when they feel unable to work out the technical hitch
or problems.
• The newly installed welder or which haven't been in use
for some time need s to be surveyed the insulation
resistances between each winding and every winding to
case with millimeter, which can not be less than 2.5MΩ.
• Keep from the rain, snow and long term exposing to
sunlight when welder is used outdoor.
• If the welder is not in use either for a long time or
temperature ranges from -25 ~ ﹢55ºC, and
the relative humidity can not be more than 90%.
• The professional maintenance personnel should use dry
compressed air (use air compressor or bellows) to
remove the dust inside the machine. The part adhering to
grease must be cleaned with cloth while make sure there
are no loosing parts existed in the tightened places and
connected cable. Usually the machine should be cleaned
once a year if the dust accumulation problem is not very
serious, while it needs cleaning once or even twice every
quarter if the dust accumulation problem is serious.

Sticking welding steps
a) Debugging before welding
• Set the "welding mode switch" on "stick", it means
the Stick welding can be used.
• Set the welding current via welding current adjuster
b) Welding
• Take up the electrode holder, install the electrode,
aim at the welding line, scratch the work piece to start
the arc. The "working" indicator is on
• Regularly check the input & output cables of welder
to guarantee them right and firmly connected and avoid
them being exposed. Check should be taken once every
month when fixed using and every check taken when
removing.
• Regularly check the seal performance of gas system,
whether the fan and feeder motor having abnormal sound
and whether every joint being loose.
• Keep torch cable direct when welding.
• Regularly clean the splash of nozzle (cannot use the way
similar to knocking the torch head) and stick to using
splash ointment. Don't remove the feeder device by
means of pulling he torch cable.
• Use qualified wire, no using inferior or rusty wire.
• Clean the dust of liner with compressed air after
the welder using some time (the dust is accumulated
by friction between wire and liner roll if find it wear and
tear to prevent wire uneven feeding.
• The pressed roll can not be pressed too firm to guarantee
smooth wire feeding. (It will lead to wire deformation,
adding the feeding resistance and accelerating the friction
of gear if pressed over firmly.)
WARNING
• The main loop voltage happens to be
a bit higher, so safety precaution should be taken
before repair to avoid accidental shock.
The untrained people are forbidden to open the case!
• Power source needs to be cut off before dust removal;
• Never tamper with wire or damage the component
parts when cleaning.
Switch off power source; Check the
main supply; Restart welder when power
recovers to normal state.
Improve the ventilation condition.
It will automatically recover when the
temperature low down.
It will automatically recover when the
temperature low down.
