METHOD OF AND POWER SUPPLY FOR ELECTRIC ARC WELDING |
摘要 |
Electric power supply for arc welding of the drop transfer type with a small diameter electrode which changes its dynamic characteristics when the drop short circuits the electrode to the weld pool. The supply is a DC power source having a short circuit current rate of rise greater than 100,000 amperes per second in series with an inductive choke which substantially reduces the rate of rise.
