    Oct 09, 2022 Selection of copper nozzle welding wire gas and confirmation of focus
    I. The use of copper nozzles The classification of copper nozzles is mainly distinguished: whether to feed wire, the size of the welding wire, the welding angle, as shown in the figure above, for an example, the inner corner wire feeding welding 1.0 welding wire uses AS-12 cooper nozzle. II. Selection of welding wire Depending on the differences of the welding plate, we need to use different welding wires (gas-protected solid cored welding wires) Stainless steel = stainless steel welding wire  e.g. ER304 Carbon steel / galvanized sheet = iron wire Aluminum = aluminum wire(As for aluminum welding wires, we recommend using more than 5 series of series of alloy aluminum. Because its hardness is high and not easy to get stuck.) III. Gas selection ①There are two kinds of easily seen nitrogen or argon. As for welded stainless steel, we recommend using nitrogen because that welding effect is better. But be sure do not use mixed gas or nitrogen dioxide gas. ②Air pressure requirements: the flow meter is not less than 15, and the pressure gauge is not less than 3 IV. focus Usually, 0 joule welding is used (0 of the scale tube does not mean that the focus is 0, which is affected by the laser. So we’d better be subject to the actual situation)

    Thank you for choosing PES fiber laser welding machihne. This User Guide provides important safety,operation, warranty and other information. Please read it carefully before you use this product. In orderto ensure safe operation and optimal performance of the product, please follow the warnings, cautions,operating procedures and other instructions accordingly. Symbols Used in this User Guide WARNING: Refers to a potential hazard that may lead to a personal injury or death. CAUTION: Refers to potential a hazard that may lead to a minor personal injury or product damage. Laser Classification This series of lasers are classified as a high power Class 4 laser instrument according to the European Community standards EN 60825-1, clause 9.This product emits invisible laser radiation at or around a wavelength of 1080 nm, and the total light power radiated from the optical output is greater than 100W~2000W (depending on model). Direct or indirect exposure of this level of light intensity may cause damage to the eyes or skin. Despite the radiation being invisible, the beam may cause irreversible damage to the retina and/or cornea. Appropriate and approved laser safety eyewear must be worn all the time while the laser is operating WARNING: You must use appropriate laser safety eyewear when this device is operating. The laser safety eyewear is selected according to the range of wavelengths emitted from this product. The end user must ensure that the laser safety eyewear being used protects against light emitted by the device over its entire range of wavelengths. Please verify that the personal protective equipment (e.g. enclosures, viewing windows or viewports, eyewear, etc.) being utilized is adequate for the output powerand wavelength ranges listed on the product. Safety Labels These safety labels include warning labels, apertures through which laser radiation isemitted and labels of certification and identification,etc. Specifications of these labels are as follows: 1.Aperture Label 2.Class 4 Laser Product 3.Class 2M Laser Product Label for Guide Laser 4. CE Compliance 5. Identification Plate 6.Laser Radiation Hazard 7.Electrical Hazard Optical Safety Any dust on the end of the collimator assembly can burn the lens and damage the laser. CAUTION: If the output of the device is delivered through a lens withan anti-reflection coating, make sure that the lens is of good quality and clean. Electrical Safety (1) Make sure your product is grounded through the PE line of the AC power cord. The grounding must be firm and reliable WARNING: Any interruption from the protective earth will electrify the enclosure, which may result in personal injury. (2) Make sure that the correct voltage of the AC power source is used. CAUTION: Failure to connect the correct voltage could damage the product. There are no operator serviceable parts inside, so do not try to remove covers, or electrical shock may be caused, and warranty will be void. Other Safety Rules (1) Never look di...
