Sanxing ZX7-315 Inverter DC manual arc welding machine
1.Using the most advanced inverter technology and imports of FET. Inverter rate could reach 100KHz.
Fast dynamic response,Functional,Excellent performance. Can meet the requirements of high-quality welding.

2.High duty cycle. The margin of welding power is large. Can welded long-term. It can still be stable welding when the cable extension 100m.

3.Automatic compensation of voltage fluctuations.Strong resistance to power fluctuation.Welding current stability.

4.With thrust compensation.Good arc stability,melt pool well mixed,minimal splash,weld line forming beautiful.

5.Down cellulose electrode for welding.Also suit to various brands of welding rod. Especially for welding low medium carbon steel,low-alloy steel,stainless steel etc with basicity welding rod.

6.Used in oil pipeline,chemical industry,repairer industry,shipbuilding industry,Power Construction,
Aerospace industry,war industry,building trade,etc.
