Safety（安全）:All persons brazing must wear Safety Glasses tinted to #3 Green – NO Exceptions所有焊接人员都必须戴上# 3绿色防护眼镜–没有例外。Joint Fit（接头配合）:Manual swage depth will follow the listed parameters for secondary tube insertion.手工弯管深度参照下列第二根管的插入参数。1/4”tube（管）5/16” deep swage（深弯管）3/8” tube3/8” deep swage1/2” tube1/2” deep swage5/8” tube3/4” deep swage3/4” tube3/4” deep swage7/8” tube15/16” deep swage1” tube15/16” deep swageCorrect brazing rod and flux selection:正确的焊接棒和流量的选择：Copper to Copper（铜/铜）6% PN 334479Copper to Brass（铜/黄铜）6%PN 334479Copper to Copper（铜/铜）6%HPPN 0440219 Low Temp Application低温应用Copper to Cupronickel（铜/白铜）6%HPPN 0440219Low Temp ApplicationCupronickel to Cupronickel（白铜/白铜）6%HPPN 0440219Low Temp ApplicationCupronickel to Cupronickel （白铜/白铜）15%PN 334480Cupronickel to Copper（白铜/铜）15%PN 334480Stainless Steel (SST) to SST（不锈钢/不锈钢）56%PN 0440154Stainless Steel (SST) to Copper（不锈钢/不锈钢）56%PN 0440154Paste Flux shall be used on all braze joints EXCEPT Copper to Copper焊膏应用于除铜铜以外的所有焊接接头Applying Flux to Braze Joint铜焊的用量Paste flux will be applied in a light or sparingly manner. Over fluxing can cause unit failure.焊膏用量要少或谨慎使用。过量会引起机组故障。Gas cylinder settings (Oxygen and Propane (LP)):气体设置（氧气和丙烷（LP））：Oxygen regulator should be set between:18 - 22 psi氧气调节器设置范围：18 - 22磅/平方英寸LP regulator should be set between:10 - 12 psi低压调节器设置范围：10 - 12磅/平方英寸Torch Flame Setting:火焰的设置：Correct Setting正确的设置Joint Prep:预焊：Braze joints shall be cleaned with an abrasive cloth or a brush that is the proper size for the I.D. of the swaged tube. Wipe debris from tube after brushed clean.焊接接头应用砂布或内径大小合适的毛刷打磨清洁。清洁后碎屑要擦干净。Nitrogen purge:氮气吹扫：A nitrogen purge tube will be at each torch station that brazes refrigerant circuits. 氮气吹扫应用在每一个焊接的制冷剂回路。It is not necessary to nitrogen purge a water circuit. 水通路没必要用氮气吹扫。The nitrogen purge pressure will be set between 2 – 5 psi on the flow regulator.在流量计上氮气吹扫压力设置在2–5磅/平方英寸之间。Inset Nitrogen line in the end of the tube 在管的一端插入充氮气管Here the Nitrogen line is inserted
