Product Description:

Performance characteristics

The main circuit using SCR control technology, the circuit is simple, easy to maintain

More characteristic output. For submerged arc welding, carbon arc gouging and other welding processes
Has excellent ability to compensate the grid, when the network voltage within ± 10% change, the current rate of change of 1% or less.
Has good dynamic characteristics, small splash.
Extremely wide current range.

Scope:
For carbon steel, alloy steel, tool steel and other metals for all position welding.
