Overview
A frozen walkway, a weedy fence line or a roofing job is the kind of spot this Flame King torch targets: a propane burner with a piezo igniter that lights itself and a flame that adjusts. A hose links it to the fuel.
Self-igniting means no striker to carry, and the adjustable flame lets output be matched to the job. A certification mark and a stated peak temperature back up the heavy duty claim. The included components field lists the torch alone, so the fuel side is up to the buyer.
Who it's for
Homeowners with weedy walks and driveways, and people who melt ice or work on a roof, will use the igniter and the flame control. Buyers wanting an all-in-one kit with a tank, or the lightest possible tool, should check the full listing first.
Pros and cons
- Piezo igniter lights it without a striker
- CSA certification stated
- Light for its output
- Weeds, ice, snow and roofing uses
- Torch only in the included components
- Open flame needs care near dry plants
- Warranty excludes paint and finish
Performance notes
A piezo igniter creates a spark at the burner when you press it, so lighting needs no separate tool. The adjustable flame changes how much heat reaches the surface, and the stated peak temperature shows the hottest the flame gets. Output is delivered through the hose from your propane supply.
