Crack. Thus, the welder should create a convex shaped pit, will be compensated convex welding shortened form. Power pick: in the selection of welding aluminum gas metal arc welding machine voltage division, the primary demand of thinking is perhaps splashing droplet transfer pulses questions. Constant current and stable voltage arc welding machine can be used to erupt. Eruption arc is very small drops of molten metal through the arc on the electrode to the base metal on top of the eruption. The use of thick aluminum welding required beyond 350 amps of welding current constant current, this ability to achieve the best effect. Pulse transition is usually carried out under the support of the inverter. The power supply includes a new built-in pulse program. In gas metal arc welding pulse after midnight, there is a drop of each current pulse welding filler metals to the transition from the workpiece, the disposal process, will take place the positive droplet transfer, spatter and reach the role of higher welding speeds less . Using pulsed gas metal arc welding technology aluminum division, to control heat input is also very good, but also can easily be misplaced welding, so the welder macro high aluminum platform lifts child factory was established in 2008, is located in Henan Province - Zhengzhou City, is a professional production of aluminum ladders: aluminum household ladder, household ladder aluminum, aluminum lift, multifunction aluminum ladder, aluminum bamboo ladder, aluminum lift platform, lifting platform, lifting chain platforms, hydraulic lifting platform, insulation ladder, herringbone ladder insulation, insulation ladder extension ladder shrink and other manufacturers, good quality, excellent price! ! !
