Joining thin aluminum alloy is difficult using most welding techniques Many of problems associated burn-through by the high heat input Common welding techniques are TIG, MIG, and MIG-PULSE welding The VP-GMA W provides more control of the heat balance m the welding arc by taking advantage of the different arc characteristics obtained with each of the two polarities.<br/> In this paper, we proposed new VP GMA Welding method by control DSP 320C32, and the characteristic and experiment result-voltage, current, welding bead, penentraion by this method are presented
