SAW 1000E

SKU : SAW 1000E

Model:SAW 1000E

Inverted AC/DC submerged arc welding machine（double characteristics）

Functions:

Submerged-arc welding, carbon arc gouging and manual metal-arc welding.

Application industry:

Shipbuilding, boiler, bridge, steel structure and wind tower.

Features:

◆ The main circuit adopts high-power single inverter technology, with both AC and DC load rates reaching 100%, and the overall performance is better than that of ordinary AC transformers;

◆ Selecting a grating motor with accurate wire feeding speed, fast motor response speed, stable AC forming, and good weld forming;

◆ Using internal IGBT to switch output polarity, the success rate of AC arc starting is higher than that of ordinary AC transformers;

◆ Precise control of AC commutation, fast and smooth arc starting, stable AC arc compared to ordinary AC transformers, without arc breaking phenomenon;

◆ The AC duty cycle, AC frequency, and DC bias can be continuously adjusted. Customers can flexibly set welding parameters according to on-site requirements, and different penetration depths, widths, and deposition rates can be obtained.
