Any welding hobbyist will tell you: buying a new solder paste is like choosing a new car. There are so many options to consider. Honestly, every welding specialist or amateur will tell you that only 3 features actually matter when you buy these necessary elements:

  • Lead-based or lead-free structure;
  • Alloy ratio;
  • Water-washable or no-clean;

I decided to focus on these three parameters as well. I picked 30 different products and tested them in equal conditions, more or less. The results are reflected in the rating you see on this page. The choice wasn’t that hard but there are a few factors a seller may hide or “forget” to mention when you buy this paste.

How did I select 3 major products for my rating?

  • Temperature Solder Paste is fully compatible with T4 industry standard;
  • MG Chemicals has a great “wettability” rate and useful dispenser;
  • 247 is another T4 industry standard paste, with 2 dispensing tips;

Other picks in my list are also good, at least, according to my tests. All brands are reputable enough to recommend – Chip Quik, Grade, Silver Easy, Kester, etc.

Actually, you should ask yourself before buying – what strengths, properties, operating temperatures, preferred method of soldering, different metals, and compatibility with welding machines do I need? You may ask your questions here, be happy to help if I can. Make sure to leave your comments about this guide. I can make mistakes and bad choice that is why I try to update each written review regularly. Thanks for reading!

  1. Solder paste is super important for soldering projects. I have used a temperature solder paste in the past with an injector, but have tried different pastes over the years. Over time, I hope to gain a little more experience reworking with solder paste so I can use it more confidently on upcoming projects.
