The naked eye cannot tell the difference. Here&#8217;s how to verify: bend the transformer lead wire firmly \u2014 pure copper flexes without breaking; aluminum wire snaps. Alternatively, weigh the transformer against spec \u2014 copper is significantly heavier for the same size.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">YGPACK&#8217;s Commitment: Every YGPACK machine ships with a certified pure copper transformer. We publish the copper weight(in grams) on every product spec sheet and welcome customers to disassemble and verify upon receipt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>The transformer is the heart of any impulse heat sealer.
