Introduction :

Manual metal arc (MMA)welding ,also known as shieded metak arc welding (SMAW), flux shielded arc welding ir informally as stick welding, is a manual arc welding process that uses a consumable electrode coaed in flux to lay the weld. An electric current, in the from of either alternating current or ditect current from a welding power supply,is used to form an electric arc between the electrode and the metals to be joined. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag,both of which protect the weld area from atmospheric contamination.


Because  of the versatility of the process and the simplicity of its equipment and operation, MMA welding is one of the world's most pupolar welding processes. It dominates other welding processes in the maintenance and repair industry, and though flux-cored are welding is growing in popularity, SMAW continues to be used extensively in the construction of steel structures and industrial fabrication. The process is used primarily to weld iron and steels, but stainless steel can also be welded with this method.

Strict Quality Control:

1. Our quality starts from the elemets. All parts are full new,refusing the used one .Our machine mainboard is made by ourself all the parts was in strictly controling .

2. Our quality controling systems are stopping the defect before packing; So we arrange at least 5 QC stations, In an assembling line ; then every tiny part in the charge of one worker ,even every screws should be marked

3. The scientific production management 6S , prevent the mistakes by human being at the upper limits

4. Our products are strictly tested 100% before delivery, and approved by CE.  And our products are able to meet or exceed some of the industry's most rigid standards. We can ensure you will be satisfied with  both performance and durability
