This is a safety feature, not a defect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reason 2 \u2014 Transformer Burnout (The Real Problem in Cheap Machines) Aluminum and copper-clad aluminum transformers generate far more heat per cycle than pure copper due to higher electrical resistance. Under continuous operation, the insulation layer on the windings melts \u2014 causing either permanent failure or dangerously frequent shutdowns.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Continuous Duty Comparison:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"226\" src=\"https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1-1024x226.png\" alt=\"\" class=\"wp-image-3528\" srcset=\"https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1-1024x226.png 1024w, https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1-300x66.png 300w, https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1-768x170.png 768w, https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1-18x4.png 18w, https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1-600x133.png 600w, https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1-150x33.png 150w, https:\/\/ygpack.com\/wp-content\/uploads\/2026\/06\/image-1.png 1358w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">YGPACK&#8217;s Solution: Pure copper transformer + dual-stage thermal protection circuit + thickened heat-dissipating chassis.
