Setup

Refilling the Butane Torch:

The Weller WE-WLTBUM2 Mini Butane Torch is shipped without fuel. You will need to purchase high-quality butane fuel separately.

  1. Ensure the torch is completely cool and the flame adjustment is set to the minimum position.
  2. Hold the torch upside down.
  3. Insert the nozzle of the butane fuel can directly into the refill valve at the bottom of the torch.
  4. Press down firmly for 5-10 seconds. You may hear a hissing sound, which is normal.
  5. Repeat the process 2-3 times to ensure a full refill.
  6. Wait a few minutes after refilling before attempting to ignite the torch to allow the gas to stabilize.

Note: If you experience difficulty refilling, ensure the butane can nozzle is properly aligned with the torch's refill valve. Some butane cans may require an adapter, though typically not for this model.
