It features a D16×F60×5.0mm collimating lens, which is different from the D20×F60×5.0mm lens used in the SUP20S\/T. Most mechanical parts are interchangeable, but optical components are model specific.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What power range is this welding torch suitable for?\u003c\/strong\u003e\u003cbr\u003e\nA: The CQWY SUP21T welding torch is designed for fiber laser welding machines with power ranging from 1000W to 2000W. It is compatible with most mainstream laser welding machines on the market that use the SUP21T interface.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace the protective lens?\u003c\/strong\u003e\u003cbr\u003e\nA: Under normal operating conditions, the protective lens should be replaced every 1-2 weeks. However, it should be replaced immediately if you notice any film burning, scratches, or if welding quality deteriorates. Frequent welding of reflective materials like aluminum and copper will accelerate contamination.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I purchase individual replacement parts separately?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, we offer both the complete welding torch assembly and all individual replacement parts separately. You can select exactly what you need from our product options, allowing you to save money by only replacing the damaged components.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Are the optical lenses compatible with other CQWY models?\u003c\/strong\u003e\u003cbr\u003e\nA: No, optical lenses are model specific. The D18×T2mm protective lens and D20×F150×4.5mm focusing lens are compatible with SUP20S\/T, but the D16×F60×5.0mm collimating lens is unique to the SUP21T and cannot be used with other models.\u003c\/p\u003e\n\n\u003cp style=\"margin-top: 30px; padding: 15px; background-color: #e3f2fd; border-radius: 4px;\"\u003e\n  View our full range of \u003ca href=\"https:\/\/www.linkmetalcnc.com\/collections\/laser-welding-accessories\" style=\"color: #1976d2 !important; text-decoration: none; font-weight: 500 !important;\"\u003elaser welding accessories\u003c\/a\u003e including nozzles, ceramic rings, protective lenses and more.\n\u003c\/p\u003e","brand":"Link Metal CNC","offers":[{"title":"Protective Lens D18×T2mm","offer_id":47980496519390,"sku":"LMCNC-CQWY-SUP21C-PART-PROTLENS-D18-T2","price":0.99,"currency_code":"USD","in_stock":true},{"title":"Focusing Lens D20×F150×4.5mm","offer_id":47980496552158,"sku":"LMCNC-CQWY-SUP21C-PART-FOCUSLENS-D20-F150-4.5","price":8.27,"currency_code":"USD","in_stock":true},{"title":"Collimating Lens D16×F60×5.0mm","offer_id":47980496584926,"sku":"LMCNC-CQWY-SUP21C-PART-COLLIMLENS-D16-F60-5.0","price":8.27,"currency_code":"USD","in_stock":true},{"title":"30×14×2mm Reflective Lens with Bracket","offer_id":47980496617694,"sku":"LMCNC-CQWY-SUP21C-PART-REFLECTLENS-30X14-BRACKET","price":21.27,"currency_code":"USD","in_stock":true},{"title":"Handheld Laser Welding Torch","offer_id":47980496650462,"sku":"LMCNC-CQWY-SUP21C-PART-TORCH-ASSY","price":389.99,"currency_code":"USD","in_stock":true},{"title":"Focusing Lens Assembly","offer_id":47980496814302,"sku":"LMCNC-CQWY-SUP21C-PART-FOCUSLENS-ASSY","price":42.53,"currency_code":"USD","in_stock":true},{"title":"Protective Lens Assembly","offer_id":47980496715998,"sku":"LMCNC-CQWY-SUP21C-PART-PROTLENS-ASSY","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Switch Button","offer_id":47980496879838,"sku":"LMCNC-CQWY-SUP21C-PART-SWITCH-BUTTON","price":8.74,"currency_code":"USD","in_stock":true},{"title":"Fixed Mounting Plate","offer_id":47980496748766,"sku":"LMCNC-CQWY-SUP21C-PART-FIXED-PLATE","price":41.35,"currency_code":"USD","in_stock":true},{"title":"Bolt","offer_id":47980496683230,"sku":"LMCNC-CQWY-SUP21C-PART-BOLT","price":10.63,"currency_code":"USD","in_stock":true},{"title":"Collet","offer_id":47980496781534,"sku":"LMCNC-CQWY-SUP21C-PART-COLLET","price":17.72,"currency_code":"USD","in_stock":true},{"title":"Connecting Block","offer_id":47980496847070,"sku":"LMCNC-CQWY-SUP21C-PART-CONNECTING-BLOCK","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Cleaning Accessory Kit","offer_id":47980496978142,"sku":"LMCNC-CQWY-SUP21C-PART-CLEANING-KIT","price":54.35,"currency_code":"USD","in_stock":true},{"title":"Galvo Motor","offer_id":47980496945374,"sku":"LMCNC-CQWY-SUP21C-PART-GALVO-MOTOR","price":99.0,"currency_code":"USD","in_stock":true},{"title":"Multi-functional Connecting Cable Short Version","offer_id":47980496912606,"sku":"LMCNC-CQWY-SUP21C-PART-CABLE-SHORT","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/8858\/5950\/files\/link-metal-cnc-cqwy-sup21t-welding-torch-parts-01.jpg?v=1773379186","url":"https:\/\/www.linkmetalcnc.com\/products\/cqwy-sup21t-handheld-laser-welding-torch-parts","provider":"Link Metal CNC ","version":"1.0","type":"link"}
