Tips here to help you choose the best laser marking machine @1.There are 10W/20W/30W,Which power should I choose. Common Fiber Laser Power 10W/20W/30W/50W ,The bigger power, marking efficiency would be greater. --20W fiber laser engraver is the most pop choice. Basic 20W fiber laser can meet 90% work. --10W is good for shallow marking work. --30W for some deep engraving, or match with big size F-theta lens for big size marking. The bigger power,price would be higher. Your machine model is equipped with 20W @2.There are many sizes for the machine,which size should I choose ? --SF110 110X110mm Small size, Deep engraving. --SF160 160x160mm Standard device for Smartech. --SF300 300x300mm For big size engraving.(200$ extra) - -Customized size,such 500*500mm/700*700mm etc Package First layer is film,second layer is protective strong foam,third layer is Strong wooden case Size/Weight 900*790*1550mm/870X500X720mm(Table type/portable type) Gross weight is:350KG/70KG(Table type/Portable type) Delivery Time Within 3 working days after get deposit Payment 30% T/T in advance, 70% before delivery Warranty Time 2 years (replace parts during warranty(no human reason)) Certificates Could provide CO/CE/SASO/CIQ/Invoice etc Certificates for customs clearance *Application: Metal materials:stainless steel,aluminium,copper,silver, gold, carbon steel etc Non-metal materials :plastic,pvc,rubber,glass,stone,wood,feather,jewelry etc *Software EZCAD original version interface Very easy to operate,comes with user manual.Machine support six languages,USA English, English,Japanese,Korean,Chinese *Main functions of the software: Users can design their graphics freely.
