INTRODUCTION
This DC Inverter Arc Welder is designed to be
used with the advanced MOSFET and rapid re-
covery diode as its main control and transfer
components and assisted with the specially de-
veloped control circuit, it has uniformly regu-
lated welding current which enable the weld-
ing power source to achieve the adaptability
to the excellent welding procedures. It largely
enhanced the welder's protection abilities to
ensure safety welding operation. It is quite
popular in welding the materials like low-car-
bon steel, stainless steel, high-intension steel,
alloy steel and cast iron.
The highlighted characteristics of series DC In-
verter Arc Welder:
a) Featured with small volume and light
weight, it widely used in upholstering field,
repairing field and fieldwork.
b) Excellent arc-piloting feature and melt &
drip transition feature.
c) By various sound protection performance, it
can keep the welding machine from overheat-
ing, over voltage, under voltage, over current
and so on. When the main supply compensa-
tion is not less than ±15%, it can increase while
the welding current reduces. Because of its anti
jamming high performance, the control system
can respond to the power source, work piece,
electrode and operational changes with less
than 1m/s speed in order to keep steady out-
put of the current.
d) Easy connection. To conduct external con-
nection, this inverter use all the connectors,
which can facilitate quick and safe connection
with simple but reliable performance. No noti-
fication will be given if the manual's content or
welder's function change.
PERSONAL SAFETY
• Please always follow the rules that conform
to safety and hygiene. Wear protective gar-
ments to avoid injuries to eyes and skins.
• Use the welding helmet to cover your head
while working with the welding machine. Only
by viewing through the filter lens on the weld-
ing helmet can you watch your operation.
E N G L I S H •
• Under no circumstance can you allow any
part of your body to touch the welder's output
bipolarity (the handle of electrode holder and
work piece.).
GENERAL SAFETY RULES
• This DC Inverter Arc Welder is an electronic
product whose spare parts are very tender, do
not change or adjust with a rush otherwise the
switch will be damaged.
• Check the connection to see if it is well con-
nected, whether the earth (ground) connec-
tion is reliable, etc.
• Fumes and gases produced when welding
are hazardous to health. Make sure to work in
places where there are exhaust or ventilation
facilities to keep fumes or emissions away from
the breathing zone.
• Please remember to keep arc rays away from
the other nearby people when welding. This is
only due to the interference from arc rays.
• Never allow anybody else other than the
operator himself to dislocate or modulate the
welding machine.
• Never allow the people with the cardiac
pacemaker or any other things which are sus-
ceptible to the electromagnetism to get close
to the welding machine, which has interfer-
ence with the pacemaker's normal function.
• The welder can not be used for pipeline ice-
out.
• Over-load is forbidden. Please noted the
rated continuous loading factor
INSTALLATION PREPARATION
• Careful precaution must be taken to keep the
operator and the machine from the foreign
materials falling from up above.
• The dust, acid and erosible dirt in the air at
the job site can not exceed the amount re-
quired by the norm (excluding the emission
from the welder).
• The welder must be installed in the place
where it can not be exposed to sun and rain.
Also it must be stored in less humid place with
the temperature range at -10~40˚C.
• There should be 50 cm space about for the
welding machine to have good ventilation.
