Thyristor Rectifying Arc Welding Machine



Thyristor Rectifying ArcWelding Machine

This arc welding machine is designed with thyristor rectifying working mode, and hence it comes withstrong compensation capacity to resist voltage fluctuation.
1. The arc force is adjustable, and the electric arc is stable. Meanwhile, arcstrike performance is reliable. So, the welding joint is good looking andaesthetical in appearance.
2. The welding current can be adjusted from either a long distance away or ashort distance away, so the thyristor rectifying arcwelding machine is easy to use.
3. The welding equipment is applicable for various welding rod, especially lowalkaline welding rod.
4. MMB thyristor rectifying arc welding machine witha welding current of 630Aor above is also suitable for carbon arc gouging, and can also serve as thepower supply for submerged arc welding.
