SA630/SA1000/SA1250 Series Submerged Arc Welding Machines (SAW)

Widely used in welding of Medium and Thick Plates.

Supports constant current (CC) and constant voltage (CV) modes.

Wire diameter: 1.6、2.0、2.4、3.0

Welding material types: Carbon steel and its alloys, stainless steel.

Real-time calculation and display of weld energy.

Precise control during arc ignition, achieving a near-100% arc ignition success rate.

The welding process is divided into three independent stages: arc starting, welding, and arc ending, allowing for the use of different welding parameters.

Precise waveform control during welding ensures excellent welding performance.

Supports weld pool stirring for enhanced penetration and improved weld formation.

Supports arc characteristic adjustment for improved arc stability and a wider current and voltage welding range.

Micro-control technology during arc ending and ball chipping adjusts the arc crater fullness and eliminates wire end balls.

Intelligent wire feed control achieves constant penetration and adapts to changes in wire feed resistance.
