Product Information

About this item

• 【Basic Performance】: This Preciva hot knife comes with a digital display and heats up in just a few seconds. It runs on 80W, 110V-127V, and the temperature goes from 200°C up to 600°C (that’s 392°F to 1112°F). Cuts through PE foam, XPS foam boards, and other foam materials nice and clean – no dragging or rough edges.
• 【Temperature Control】: There are 20 adjustable settings – just turn the dial. If it gets too hot, the overheat protection kicks in (you’ll see “OTT” on the screen) and it resets itself within about 30 seconds. That helps the blade last longer without burning out.
• 【What the Display Number Actually Means】: The digital screen shows a number – but that number is not Celsius or Fahrenheit. It's a reference value. To get the actual temperature in Fahrenheit, use this: °F = (display value × 9) + 212. For example, when it shows 20, the real temp is 20×9+212=392°F. When it shows 100, that's 100×9+212=1112°F. One thing to note: different blade lengths may cause slight temperature variations – that's normal. Also, the display starts at 20, not zero.
• 【Blade & Material Quality】: Comes with three high-temp resistant nickel-chromium blades – one 20cm long and one 10cm long (plus a spare). The blade holder is pure copper, so heat transfers fast and spreads evenly. There’s also a metal hook on the back – hang it up when you’re done, keeps your workspace tidy.
• 【What You Can Cut】: It’s not just for foam. Works on PE foam, XPS boards, EPE foam, rope, fabric, insulation materials – pretty much anything you need a hot cut for. Great for DIY projects, model building, cosplay props, insulation work, packaging, or general workshop use.
• 【Quick Tips】: Start with a lower temperature and work your way up – no need to max it out right away. Use the included wrench to tighten the blade properly and make sure it makes good contact. The overheat protection will do its thing automatically, so don’t worry. Just watch the digital readout and adjust as you go – no guesswork.
