China Suppliers Factory Integrated MIG 250A Gasless Welding Machine with Upgraded Control Board and Enhanced Heating Effects
Detailed Information
- The installation area should be firm enough to support the welder.
- It is forbidden to install the welder in places where water splashes may be generated, such as water pipes.
- Welding operations must be performed in a relatively dry environment where the air humidity is normally not greater than 90%.
- The ambient temperature shall be between -10°C and +40°C.
- Do not perform welding in dusty or corrosive gas-containing areas.
- Do not place the welder on a tabletop with an inclination greater than 15°.
The welder has been installed with overvoltage, overcurrent and overheating protective circuits. When the grid voltage, output current and internal temperature exceed the set standards, the welder will stop working automatically; but excessive use (such as excessive voltage) will still cause damage to the welder, so the following matters shall be noticed:
In general, the automatic voltage compensation circuit inside the welder will ensure that the welding current is kept within the allowable range. If the supply voltage exceeds the allowable value, it will damage the welder.
Operators shall use the welder according to its allowable load duration rate and maintain the welding current within the maximum allowable load current. Current overload will remarkably shorten the life of the welder or even burn it.
If the welder exceeds the standard load duration rate in working, it may suddenly enter the protection state and stop working. This indicates that once the standard load duration rate is overtaken, it will heat up to trigger the temperature control switch to stop the welder, and the yellow indicator light on the front panel is on at the same time. In this case, do not pull out the power plug. Let the fan cool down the welder. When the yellow indicator light is off and the temperature drops to the standard range, start welding.
Main Features
- All movements adopt the latest and mature IGBT full-bridge inverter technology.
- IGBT inverter technology, less welding spatter and beautiful welding seams.
- Complete undervoltage, overvoltage and current protection, safe and reliable.
- Accurate digital display of current and voltage preset, easy and intuitive operation.
- High pressure and slow wire feeding to start the arc, the arc will not burst the wire, and the arc will be closed to remove small balls.
- Constant voltage output characteristics, CO2 welding, one machine for multiple purposes.
- With self-locking/non-self-locking mode, greatly reducing operating intensity.
- Three-proof design for key parts, suitable for various harsh environments, with stable and reliable operation.
