arc welding machine

MZ(D series automatic submerged arc welding machine adopts flat and dropping d.c power supply (ZD5) series crystal brake tube arc welding rectifier and automatic submerged arc welding.It can weld butt-jointed seam or angle joint seam with or without groove,internal and extemal circular seam of circular vessel and longitudinal seam. The welder introduces advanced technology of crystal brake rube control of 1990s.All electronic elements are strictly aged and screened.Control performance is perfect and mature,It has high reliability and stability. The welder has two characteristics of submerged arc welding vertical dropping and flat movement as well as CO:/MAG flat welding.Welding trolley has two characteristics of constant wire feeding and variable-speed wire feeding. Flat and dropping characteristics,applicable to submerged arc welding manual welding and carbon arc gouging. Excell ent performance,smooth and beautiful welding seam,outstanding arc starting with 100% success rate. Power compensation function,welding current deviation <±2.5% dunning ±10%power deviation. Overcurrent,overload and overheat protection to improve product quality.
