Portable Butane Soldering Iron 35W

The Weller ML500MP is a 35 watt butane-powered mini iron designed for field technicians and hobbyists who need soldering capability without mains power. It suits on-site repairs, automotive wiring and heat-shrink work where a power outlet is unavailable.

Sustained Heat Output 750-900°F

The adjustable gas flow valve lets the user set tip temperature between 750 and 900 degrees Fahrenheit for consistent output during extended joints. Piezo ignition lights the iron instantly, and the butane reservoir maintains temperature without the thermal droop common in battery tools.

Refillable Tank with Piezo Ignition

Refilling uses standard butane canisters through a bottom valve; the built-in piezo igniter removes the need for a separate lighter. Over-filling can cause flare-up, so stop when liquid butane appears at the vent. A clogged tip orifice is the usual cause of weak flame and clears with a fine wire.

Questions about this item

How hot does the tip get when the ML500MP runs continuously?

The tip temperature ranges from 750 to 900 degrees Fahrenheit, controlled by the adjustable gas flow valve.

What fuel does the ML500MP need before I can use it?

It runs on butane gas, which must be purchased separately and refilled into the iron's tank.

Can I use the ML500MP for the same heat-shrink jobs I do with my electric iron?

Yes, it is designed for soldering, heat-shrink tubing and electronics work, with a 35-watt equivalent output.
