Weller-Portasol P2 Cordless Soldering Tool User Guide
Product Overview
The Weller Portasol Butane Soldering Iron is a self-igniting, gas-powered soldering tool designed for high portability and versatile use. It reaches operating temperature in just 30 seconds, offering adjustable heat levels up to 450°C (842°F).
How to Use Weller Portasol Butane Soldering Iron
Step 1: Refill with Butane Gas
- Ensure the soldering iron is cool and turned off.
- Invert the unit and press a butane refill can firmly into the filling valve.
- Let the iron rest upright for 2 minutes to stabilize internal pressure.
Step 2: Turn On and Ignite
- Slide the ON/OFF switch forward to begin gas flow.
- Press the piezo ignition button (usually a separate red button).
- You’ll hear a click followed by a soft flame sound.
- Wait 30 seconds for the tip to reach optimal temperature.
Step 3: Adjust the Temperature
- Fine soldering: Lower setting
- Circuit board repair: Medium setting
- Heat shrink tubing or de-soldering: High setting
Step 4: Use the Correct Tip and Mode
- For general soldering: Use the chisel or conical tip
- For heat shrink tubing: Attach the hot air nozzle
- For torch applications: Remove tip for open flame mode
Step 5: Begin Soldering
- Clean the tip using a damp sponge or brass cleaner.
- Apply solder to the hot tip briefly to “tin” it.
- Place the tip on the joint, apply solder wire, and allow it to flow.
- Remove the iron and let the joint cool.
Step 6: Turn Off and Store Safely
- Slide the ON/OFF switch back to shut off the gas.
- Store in a heat-resistant pouch or tool case.
Keep away from children and direct sunlight.
How to Fill the Butane Tank
- Ensure the unit is off and cool.
- Turn the soldering iron upside down.
- Use a quality butane refill canister and press the nozzle into the filling valve.
- Wait for a slight hissing sound to stop, indicating the tank is full.
Note: Avoid overfilling and never expose the tank to temperatures above 50°C (122°F).

Troubleshooting
| Problem | Solution |
|---|---|
| Iron won’t ignite | Check butane level, refill if needed. Inspect ignition switch and try again. |
| Flame too small | Increase gas flow using control tab. |
| Tip not heating | Confirm ignition and flame. Replace worn tip. |
| Sputtering flame | Possible clogged nozzle—clean or replace. |
| Gas leak | Stop using immediately. Check seals and refill valve. |
FAQS
How does a butane soldering iron work?
- This spark ignites the butane gas flowing from the tank, creating a flame at the tip of the soldering iron.
How hot does a gas soldering iron get?
- Flame temperature 1300°C, soldering temperature 450°C and hot air temperature 600°C
What is the working principle of soldering iron?
- A soldering iron is used to heat the metal (base material) of the part to be soldered.
Which is a disadvantage of soldering?
- The soldering process generates heat in the contacts, the connector, and even in the cable.
What is the most common problem with soldering?
- A disturbed joint.
- An icy joint.
- An overheated joint.
- A solder-starved joint.
- An over-soldered joint.
- Untrimmed leads.
