Soldering Station Tips

Weller ET and LT slip-on tips

Compare ET shapes for documented ET pencils and LT shapes for documented LT pencils. If the handpiece has been replaced, check the label on the installed iron before relying on the station name.

What to check before buying

Check the pencil before choosing ET or LT

ETB and LT B both have a 2.4 mm face, but their mounting families differ. Look for the pencil model and the exact family in the Weller chart. Broad station labels such as WT or WX can cover more than one handpiece.

Choose a single profile or a pack

ETP-5 stocks five identical round ends for repeated work. The three-tip WES51 assortment adds a chisel and a longer taper. For a recessed LT joint, LT K, LT L and LT M share a long profile with different face widths.

Questions about this tip family

Will an older ETS fit a WEP70?

Check Weller’s exact compatibility sheet. It lists exceptions among older ET references and identifies later variants separately.

What is a useful middle width for a long LT chisel?

LT L gives a 2 mm face between LT K at 1.2 mm and LT M at 3.2 mm. Check the opening around the joint before choosing width.
