Safety warnings
During the welding process, there maybe certain security risks to the users .learning to take necessary protective measures is very important. Details please refer to personnel safety protective guidelines, which is comply with the requirements of the manufacturer accident prevention. Professional skills need to be trained, with which the users are capable to operate the equipment.
- Wearing safety gear when welding, which is approved by the national safety supervision department
- Avoid excessive work, take necessary rest.
Electric shock may result in serious injury or even death!
- Please install grounding device according to the application standard.
- Don not contact live parts with bare skins, or when wearing wet clothing.
- Make sure you are insulated from ground and work-piece
- Before working, make sure your situation is safe.
Smoke may be harmful to health!
- Keep safe distance with smoke, avoid directly breathing welding fumes.
- Please weld where there is ventilation or air circulated.
Arc light may damage your eyes or burn bare skins!
- Wearing protective clothing like glasses, mask, gloves, boots, etc. To protect eyes and skins from arc light.
- For bystanders as well.
Improper operation may cause fire or explosion.
- Welding spark may lead to fire, please ensure there is no flammables nearby.
- Make sure there is fire extinguishing device in the neighbourhood, and who is skilled to use it in working areas.
- Do not weld in sealed container
- Never use the machine for pipeline thawing.
Thermal parts can cause serious burns
- Do not touch the thermal parts.
- In continuous using, please always keep to have a cooling time.
Excessive noise may be harmful to hearing.
- Please protect your ears, use ear shield or earplugs if necessary.
- For bystanders as well.
Magnetic field is effective to heart pacemaker.
- Before consulting a physician, users with pacemaker must keep far away from the welding areas.
Moving parts may cause injury.
- Keep safe distance to moving parts such as the fan.
- All kinds of doors, panel, cover, baffle plate and protective device should be closed and put to the right place.
Ask for professional help with machine fault if needed.
- Normal faults please refer to the manual.
- If you are unable to solve the problem on your own, please seek for professional help from the supplier or manufacturer. Remark: the welder must be placed horizontally, laying place slope not exceeding 15°.

Installation and operating instructions
Warning: -Please strictly refer to the following steps to connect the
equipment.
— Avoid using the machine under rains.
— Before using. Please measure the input voltage to see if it is under machine
usable voltage range (200V-240V), otherwise will damage the welder.
- The electrode holder and earth clamp are easily connected to the machine by inserting the quick connector and twisting it clockwise. Always ensure a correct fit .Please pay attention to the connection polarity. Generally, Reverse Polarity is used in which the welders electrode holder will be connected in the ” “. Positive Terminal – while the earth clamp in the “+” Negative Terminal. The welder does have the ability to be used for Straight Polarity or Reverse Polarity, We recommend you connect the polarity in accordance with the Manufacturers recommendations. If the polarity is connected incorrectly it will cause an unstable arc, spatter, and or the electrode to stick. If these symptoms occur change the polarity.
- Turn the machine on via the ON/OFF switch located on the rear of the machine.
- Set the amperage knob according to type and size of welding rod being used.

Additional safety warnings
Working environment
- The product shall be used under a certain dry environment, humidity normally better under 90%.
- Environment temperature -10°C to 40°C is best for our products.
- Avoid welding under direct sunshine or rain, avoid water getting into the inside of machine.
- Avoid working in dusty area or areas with corrosive gases.
- 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 controlled
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!
- 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
- Pressure of compressed air must not be more than 5 bars in order to prevent damage to small components inside the machine.
- Check inside the welding machine regularly and make sure the output Terminals are connected tightly and connectors are not damaged. If burnt, loose or damaged please tighten or replace if necessary. Between of moving parts.
- Avoid water and steam entering into the machine, if the welding machine Does get wet please dry inside the machine and check the insulation of machine.
- If the welding machine will not be operated for long periods it should be put into a box or covered and stored in a cool dry area.
Troubleshooting
WARNING!
Experimentation and careless maintenance may lead to more problems to the
Machine. This will make formal diagnostic and repair more difficult.
