Put too much heat into a 0.5&nbsp;mm sheet and it warps, burns through or turns blue and brown around the joint. Every one of those problems means grinding, polishing or a rejected part.<\/p>\n<p class=\"k13\">A <strong>cold welding machine<\/strong> solves this by feeding heat into the joint in tiny, timed doses instead of a continuous arc. Here is how it works, where it beats ordinary welding, and how the CRUXWELD IceFuse&nbsp;250 handles thin-sheet work alongside TIG, pulse, weld cleaning and stick welding.<\/p>\n<div class=\"k14\">\n<h2 class=\"k16\">Why thin stainless steel is so hard to weld<\/h2>\n<div class=\"k15\">The problem<\/div>\n<\/div>\n<p class=\"k13\">Stainless steel conducts heat slowly and expands a lot when hot. With a continuous MIG, stick or standard TIG arc, heat builds up around the joint faster than it can spread away. The result is one of these three familiar defects:<\/p>\n<div class=\"k17\">\n<div class=\"k18\">\n<div class=\"k19\"><svg width=\"34\" height=\"34\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\"><path d=\"M2 12c3-6 5 6 8 0s5 6 8 0 3-3 4-2\"\/><\/svg><\/div>\n<div class=\"k20\">Distortion<\/div>\n<div class=\"k21\">The hot zone expands, then shrinks as it cools, pulling the panel out of flat.<\/div>\n<\/div>\n<div class=\"k18\">\n<div class=\"k19\"><svg width=\"34\" height=\"34\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"><rect x=\"3\" y=\"6\" width=\"18\" height=\"12\" rx=\"2\"\/><circle cx=\"12\" cy=\"12\" r=\"3\"\/><\/svg><\/div>\n<div class=\"k20\">Burn-through<\/div>\n<div class=\"k21\">On sheet below about 1&nbsp;mm, a steady arc can melt straight through.<\/div>\n<\/div>\n<div class=\"k18\">\n<div class=\"k19\"><svg width=\"34\" height=\"34\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\"><path d=\"M3 15a9 9 0 0 1 18 0\"\/><path d=\"M6 15a6 6 0 0 1 12 0\"\/><path d=\"M9 15a3 3 0 0 1 6 0\"\/><\/svg><\/div>\n<div class=\"k20\">Heat tint<\/div>\n<div class=\"k21\">Rainbow and brown oxide around the bead that must be removed afterwards.<\/div>\n<\/div>\n<\/div>\n<div class=\"k14\">\n<h2 class=\"k16\">How a cold welding machine controls heat<\/h2>\n<div class=\"k15\">How it works<\/div>\n<\/div>\n<p class=\"k13\">Think of cold welding as a row of precise stitches rather than one long seam. Each short burst of current fuses a small spot, then a pause lets the heat spread out before the next burst.

On a machine like the IceFuse 250, cold welding is low-heat fusion welding. The metal melts and fuses into a true metallurgical joint &mdash; the heat simply arrives in short, controlled bursts so the sheet stays cool and flat.<\/div>\n<\/details>\n<details class=\"k87\">\n<summary class=\"k88\">How thin can a cold welding machine weld?<\/summary>\n<div class=\"k89\">The IceFuse 250 cold mode is rated for stainless steel from 0.1 mm up to 6 mm. For thicker sections, TIG, pulse or MMA mode is usually the better choice.<\/div>\n<\/details>\n<details class=\"k87\">\n<summary class=\"k88\">Can I use it for normal TIG and stick welding too?<\/summary>\n<div class=\"k89\">Yes. It switches between Cold, TIG (HF), Pulse, Clean and MMA modes with up to 250 A, so it also covers everyday TIG work and stick welding with 1.6&ndash;4.0 mm electrodes.<\/div>\n<\/details>\n<details class=\"k87\">\n<summary class=\"k88\">Does it run on single-phase power?<\/summary>\n<div class=\"k89\">Yes. It accepts 220&ndash;240 V or 110&ndash;120 V single-phase supply, so it suits most workshops and site supplies.<\/div>\n<\/details>\n<details class=\"k87\">\n<summary class=\"k88\">Is it suitable for aluminium?<\/summary>\n<div class=\"k89\">It is best on stainless steel, mild and carbon steel, galvanised and coated sheet. For heavy aluminium work, a dedicated AC\/DC TIG welder is the better match &mdash; ask our team and we will suggest the right machine.<\/div>\n<\/details>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>How a cold welding machine welds thin stainless steel without warping or heat tint, and how the CRUXWELD IceFuse 250 combines cold, TIG, pulse, cleaning and MMA modes.<\/p>\n","protected":false},"author":4,"featured_media":7312,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-7313","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-welders","entry"],"_links":{"self":[{"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/posts\/7313","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/comments?post=7313"}],"version-history":[{"count":2,"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/posts\/7313\/revisions"}],"predecessor-version":[{"id":7323,"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/posts\/7313\/revisions\/7323"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/media\/7312"}],"wp:attachment":[{"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/media?parent=7313"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/categories?post=7313"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cruxweld.com\/blog\/wp-json\/wp\/v2\/tags?post=7313"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
