| Abstract: | The characteristics of the SCR arc welding prectifier controlled theguide droplet short circuit transfer of the CO_2 gas shield arc weldingwere sttdied. The dynamic characteristic of the power source was im-proved by the series connection of a linear reactance and a non-linearreactance in the ontput circuit, The current drop velocity of 10~5A/scould be reached, Introduced two kinds of controlling way that is theontput charateristic rapid transform from one constant current to an-other constant current and from the constant voltage to the constant cur-rent, Also introduced their ciruit principples and the experiment resultscontrast. |
