Abstract: A welding system includes a power source configured to generate power and deliver the power to a welding torch. The power is provided in accordance with an electrode negative pulse welding regime that includes a cyclic peak, followed by a stabilization phase, then a return to a background level. The stabilization phase has a generally parabolic current shape, and is performed in a current-closed loop manner until a transition point, where control becomes voltage-closed loop until the background level is reached. Resulting weld performance is improved, with a globular-like transfer mode, reduced shorts and enhanced arc stability.

Abstract translation: 焊接系统包括被配置为产生电力并将电力传递到焊炬的电源。 根据包括循环峰值的电极负脉冲焊接状态提供功率，随后是稳定阶段，然后返回到背景水平。 稳定阶段具有通常的抛物线形状，并且以电流 - 闭环方式执行，直到转变点，其中控制变为电压闭合循环，直到达到背景水平。 产生的焊接性能得到改善，具有球状转移模式，减少短路和提高电弧稳定性。
