The Buyer’s Guide

Choose the proper type of a soldering iron tip: 

Chisel (sloped) tips for common tasks. They are possibly the most popular tip style, and for many soldering activities, they are a flexible form. Chisel tips have a broad edge that helps them to uniformly spread heat through part leads and pads.

There are numerous applications where a suitable match for the work is the chisel edge. For most chisel tips, the tapered edge helps it to get between the components when required. They function great for cables, pass-through links, wider parts for surface mounting, and several connections on board.

When paired with a method for cutting the material, a chisel tip is often effective for many desoldering activities. Ideally, without overheating the materials, the tip can be scaled to accommodate the pad it is soldering. For a chisel edge, striving for 60 percent of the pad size or just over half is a decent rule of thumb.

Weller has an array of chisel tips appropriate for a large variety of applications. We’ve got fine, curved, long reach, and nice twisted chisel tip types. The bent models are accessible at angles between 30 and 60 degrees, suitable for your use.

Conical tips for precision. They have a pointed shape and are mostly used for precise applications of soldering. The cone-shaped tip supplies a given limited area with intense heat, making it well equipped for most surface-mount parts and other light jobs.

The design of any cone tip by Weller enables the conical soldering tip to get into areas that would be impossible for other tips to enter. For this purpose, keeping a conical tip is useful when you need to reach tight places. 

When using a conical edge, beginners or anyone new to soldering should use care. The sharper points are more vulnerable to harm than other tip designs, so they need to be closely treated. Many beginners prefer to add a lot of force to the soldering point, which could hurt both the edge and the job on a conical tip.

Conical tips are also applied in space-tight wire connector applications. The shape of the tip helps it to meet where most tips can be too wide to fit into the connector.

Weller houses a variety of conical tips in styles of fine, curved, broad distance, and fine bent. For your ease, conical angles are required at both 30 and 60 degrees.

Proper size and diameter

By picking the appropriate size/diameter of a soldering iron tip, then such benefits should be expected: 

  • Efficient heat transfer;
  • Good wetting for solder joints;
  • Longer life of the tip;
  • Decreased operating costs;

You must understand the size/area of the land/pad where the tip may touch in order to choose the correct size/diameter tip. If the surface region between the tip and the ground/pad is maximized, heat can be transmitted more easily than if you had a reduced contact area.

But what if the correct size tip can not be used because there is no room? You may need to find a tip in that situation that will suit the small room in which you have to operate, so it is better to make sure you use a tip that only works.

Going so little won’t heat up effectively. It is therefore best to take into consideration the usage of PCB preheating. This allows to “preload heat energy” into the PCB and components so that in a shorter period than if the same procedure was performed without preheating, the minimal heat transfer from an underpowered tip will achieve the required temperatures for quality soldering. It has also been demonstrated that nitrogen soldering adds to the solder joint’s preheating that can improve the solder’s wettability.

How to identify genuine Weller iron tips?

  • Look for the label “Genuine Weller Seal of Quality”;
  • The genuine tips are engraved with the Weller logo;
  • High-quality copper tips;
  • Universal uses – from the most delicate to the most difficult jobs;
  • Fast heating up;

How to prolong the use of Weller soldering iron tips: 

  • Tin your tips with a thin layer of solder. The tip will look shiny and become more durable;
  • Pick only premium solder, preferably lead-free products. If it is not possible, some experts recommend picking the solder products with the 60/40 ratio of tin to lead;
  • The melting temperature should correspond to the solder content. 60/40 solder products require a temperature level of 460F. While lead-free solders need about 700F;
  • Keep the tips neat and clean;
  • To treat oxidization you should use flux in a liquid or paste form;
  • If the tips got darker, you may re-activate them by using a top-notch reactivation paste with abrasives. You just need to place the tip inside the jar with this paste. Hold until the tips become shiny;
  • Do not store the tips just in the drawer/box with other metal tools. Secure them separately in a durable case;
