Arc Welding In arc welding heat is developed from an arc which is struck between the electrode and metal to be welded. In case of D.C. for producing arc 30 to 50 volt are needed whereas in case of A.C. 60 to 90 volt are necessary for strildng the arc. Following equipment is used : D.C. equipment Motor generator set-Rectifier supply. A.C. equipment Single operator type-Multiple type. Engine driver equipment When main supply is not available D.C. generators are used which are driven by internal combustion engines | |
