该型对焊机主要用于低碳钢等金属直丝或环形接头的对接。
 this butt welder model is mainly utilized in butt joint of straight wire and the ring joint of the mild steel.
该机张开电极，压紧工件一步完成，俗称“联动式”。电流调节分8级和无级调节两型，选择合适的电流档位和顶锻力，设定好焊接时间，完成焊接过程，该机生产效率高，特别适用于焊圈行业。
this welder stretches electrode and the work piece is further compressed, which is called“coordinated type”. the current settingincludes 8-gear control and infinitely variable control. the welding process is finished under the right current gear and upset force during the set time. this model is in high production efficiencyand particularly applicable in welding ring industry.
