SAFETY OPERATION
• 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 susceptible to the electromagnetism
to get close to the welding machine, which has interference
with the pacemaker's normal function.
• The welder can not be used for pipeline ice-out.
• Never using the way of knocking the torch head
to remove slag.
• The torch cable can not be pressed and its folding angle
cannot be too small. The liner radius cannot less than
300mm, or it may damage the inner cable and lead to
accident.
• Never allow anybody else other than the operator himself
to access the job site.
• No touching on the live parts such as output connector
etc. when welding.
• The torch is an important part of the welder, it has direct
influence on welding quality and it is relatively expensive.
It can not be put on the work pieces just finished welding
in case of burning out.
• The inner and outer parts of the nozzle should be daubed
with a little anti-stick ointment to prevent splash and
spatter sticking on the nozzle which is hard for clearance.
• The welder should be used within rated duty cycle.
Over load using may accelerate the components aging
and even lead to burning out.
• The gas bottle should be fixed in case of toppling over.
• No touching on the live parts while turning on power.
Input power must be cut off after finishing job or leaving
the site temporarily.
Safety Measures to Be Taken to Assure the Correct
Installation and Position
• Precaution must be taken to keep the operator and the
machine from the foreign materials falling from up above.
• The dust, acid and erodible dirt in the air at the job site
can not exceed the amount required by the norm
(excluding the emission from the welding process).
• 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 -10~40ºC.
• There should be 50 cm space about for the welding
machine to have good ventilation.
TECHNICAL SPECIFICATION
Environment to Which the Product Is Subject
• The surrounding temperature range: when welding:
-10 ~﹢40ºC,
During transport or in storage: -25 ~﹢55ºC.
• Relative humidity: when at 40ºC: ≤50%,
when at 20ºC: ≤90%.
• The dust, acid and erodible materials in the air can not
exceed the amount required by the norm (apart from
the emissions from the welding process). No violent
vibration at the job site.
• Make sure that there is no metal-like foreign body
to enter the welding machine.
• No violent vibration in the welder's surrounding area.
• Make sure that there is no interference with
the surrounding area at the installation site.
• Make sure whether there is enough power supply
to make the welding machine work properly. Any power
source required to access the welder must be installed
with some protective equipments.
• The welder should be installed on the horizontal
surface and if it over 15°, there should be added some
antidump set.
• Take measures to prevent wind while operating in
the strong wind since the welder is gas shielded.
The wind speed is limited below 1.0m/s, or the wind
shield device must be loaded.
Safety Check
Each item listed below must be carefully checked before
operation:
• Make sure that the welding machine has reliable earth
wire connection;
• Make sure that there is no short circuit connection
with welder's both outputs;
• Make sure that there is always sound output and input
wire connection instead of exposing it outside. Regular
check needs to be conducted by the qualified personnel
after the welder has been installed over a period of six
months, which involves as follows:
• Routine cleaning needs to be done to make sure that
there is no such abnormal condition as loose connection
happening in the welding machine.
• The external parts installed with the welder must
guarantee that the welder works properly.
• Check the welding cable to see if it can continue
to be used before it is worn out.
• Replace the welder's input cable as soon as it is found
to be broken or damaged.
ATTENTION
the case. Please do not hesitate to contact us
for technical assistance whenever you come across
the problems you can not work out or you may deem
difficult to fix.
• Altitude no more than 1,000m.
• Keep from raining when it is used outdoor.
Requirement for Main Supply
• The voltage oscillogram should display actual
sine wave, which must have enough capacity.
• The oscillation of the supplied voltage should
not exceed ±10% of the rated value.
