Product Description

Product Description

1.Brief Introduction 

MMA welder uses imported IGBT and fast recovery diodes as main electric components. It is supplemented by a specially developed main PCB board. In addition, the uniform regulation of welding current has been designed to guarantee the arc reach good welding process adaptability. What's more, its perfect dynamic protection features ensure that it is safe and reliable when use. It is ideal for using low carbon steel, stainless steel, alloy steel etc.

MMA  Features: 
1.25% high duty cycle.
2.Lower cost operation, more portable, more compact, superior output.
3.Excellent arc properties and solution droplet transfer.4.With the protections of over-heating, over-voltage, over-current.5.Digital display function when use (only for plastic shell).
6.Plastic handle makes it easy to carry.
7.Convenient quick connection for the output makes it quick, safe, simple and stable.

4.Transportation and Storage 

*  This machine is an indoor equipment and the attacks of rain and snow should be avoided in the process of transportation and storage. While loading and unloading, more attention should be paid on the package with words of warning. Storage warehouse should be kept dry with good air circulation and no corrosive gas or dust. The temperature should be maintained from -25ºC to 55ºC and relative humidity must be lower than 90%.
*  If the products are still needed to continue storing after stripping, repacking should be carried out according to original package's requirement. Remember before storage, don't forget to clean and seal it with plastic bags.
*  Users should maintain the cartons and shock blocks in order to be properly packaged in need of long distant transportation. For the long distant transportation, it should be retrofitted with a wooden case and mark the "up" or "rain" symbols. 

5.Quality Warranty 

If the machine is used in accordance with the regulations on the operation manual, in compliance with the rules on installation, storage, use, maintenance, safeguarding, manufacturers should provide free services for the users under the conditions of within 12 months from the date of purchase (based on the issued invoice date).
