Additional safety warnings

Working environment
(1) The product shall be used under a certain dry environment, humidity normally better under 90%.
(2) Environment temperature -10˚C to 40˚C is best for our products.
(3) Avoid welding under direct sunshine or rain, avoid water getting into the inside of machine.
(4) Avoid working in dusty area or areas with corrosive gases.
(5) The welder shall be placed horizontally, laying place slope not exceeding 15°.
Safety operation
Our products already have overload, over-current and overheat protection circuit, when input voltage, input current or machine inside temperature exceeds
the system default standard, the welder will stop working apologetically. However overusing especially with high output voltage, will fasten the damage of
welders, please pay more attention to the listed aspects.
Ventilation
During operation, there is huge current passing through the welder, natural wind is not strong enough to cool down the machines, which has to be done with
a powerful blowing fan fixed in the machine.
The operator must make sure the fan on the back of welder not covered by any obstacle, the welder must be kept with a distance at least 0.3m to the items
nearby. Using environment must be kept under well Ventilated , which helps the welder work better and extend product is using life.
Overloading
The operators must make sure the welder works under permitted duty cycle, which can be referred to in the data board on the machine.
Welding current shall be controlled under maximum overloading current allowed. Otherwise the welder is working life will reduce, even burns down.
Output voltage must not be too high
Input power voltage can be seen in the data board on the machine. Within permitted range , the voltage compensating circuit will help keep welding current
stable . If input voltage over permitted , the machine will get broken easily , the operators must be aware of this and make prevention against this.
The welder must be grounded
There is a grounding screw on the back of machine with a grounding sign beside . Before using, make sure the welder is grounded well, to prevent the operators
getting short.
Measures after duty cycle protection
When using over maximum duty cycle, inside circuit overheating causes the temperature switch to be open-circuit, which finally prevent the products from
working on. This can be judged from the lighting yellow led on face panel . Under this circumstance, no need to pull off the plug from the power, keep power
on to let the fan cool down the machine. With the yellow led turning off, welding can be continued.
Movement
When moving the welder, be careful not to be hurt by the machine.
When lifting the welder with other equipment like forklift , do not put yourself under it, to avoid being hit if the welder drops .Welding current shall be con-
trolled under maximum overloading current allowed.
Otherwise the welder is working life will reduce, even burns down

Maintenance

WARNING!
● This machine is mainly used in the welding industry. It will produce Electric & Magnetic fields , so the operator should insure proper protection/screening in
used
Earth leakage-circuit breaker should be used with this machine!!!
● During welding, DO NOT pull out or insert any plugs or cables, it can lead to life-threatening danger and cause damage to the machine.
● Before connecting cables make sure the power is off.(The correct way is to connect the cables to the machine first, and make sure they are Firmly tightened
and then connect the power plug to the power source .)
● Before maintenance and checking , power must be turned off ,
● Before opening the cover disconnect the machine from electricity!
1) Remove dust with dry, clean compressed air regularly, if the welding machine is operated in an area where the air is polluted with smoke and dust , the
machine needs to be cleaned regularly, remove dust monthly
