No, and that is the whole point. The alloy melts at about 716 F, far below the melting point of aluminum. A flame is enough: a windproof lighter, a butane kitchen torch or a small propane torch. No outlet, no helmet, no settings.

I patched the rusted-out bottom of an old aluminum pot with a kitchen lighter, in about two minutes. I figured it was a gimmick, and it actually holds. Then I rejoined the handle on my pruning shears.

Going viral on Pinterest
Ever since the lighter-repair tutorials started circulating on Pinterest, our packs have been moving fast. Stock is limited and we are not restocked every week.
Limited stock
You are throwing out metal that could be saved
A pot with a hole, snapped shears, a handle that fell off. We toss it and buy another. All it needed was a weld.
A lighter, and it is welded
No welding machine, no electricity, no training. The flame heats the metal, the rod melts into it. That is the whole job.
Built for everyday repairs
Four reasons a rod beats the tube of glue you were about to buy
🔥
No machine
A lighter or a small torch is all it takes.
💧
Watertight
Seals holes and leaks so water stays put.
🧲
Multi-metal
Aluminum, copper, brass, zinc, cast iron.
🌡
716 °F
Low enough not to burn through thin sheet.
Forget the welding machine
A welder runs $150 and up, takes up bench space and needs hours of practice. This fits in a drawer.
A weld in three steps
No training, no welding machine. If you can hold a lighter, you can do this.
1
Clean the area
Scuff the surface with sandpaper to take off rust, paint or grease. Clean metal is what makes the bond hold.
2
Heat the part, not the rod
This is the whole trick. Play the flame over the metal around the spot, not on the rod. The metal should get hot, not glowing.
3
Touch the rod down
Against the hot metal it melts on its own and flows into the joint. Let it cool for 30 seconds and it is done.
Tip: if the rod balls up instead of flowing, your part is not hot enough yet. Give the metal another 10 seconds of heat.

The complaints you will read, answered straight
We went through the one and two star reviews on cheap welding rods. Three of the four come down to technique, one is simply how the alloy behaves. Here is the honest answer to each.
🔥
"It just balls up and will not flow"
Technique, not the rod. Heat the part and let the hot metal melt the rod. Aim the flame at the rod and it will ball up every time.
🔗
"The joint cracked after two days"
Almost always an uncleaned surface. Rust, paint and grease stop the alloy gripping. Thirty seconds of sanding fixes it.
📦
"My rods arrived snapped"
Not a defect. The alloy is brittle cold, which is exactly what lets it melt so low. A snapped rod works the same, and you get 24.
🎯
"Is this real welding or not?"
No, it is low-temperature brazing at 716 °F. Great for patching and reattaching. For structural parts under load, call a pro.
30 days to try it, or your money back
Test the rods on your own parts for 30 days. If the result does not convince you, write to us and you get a full refund. You take no risk here, we do.
Your questions, answered
The eight things people ask us most before buying
Do I need a welding machine or electricity?
Do I need a welding machine or electricity?
Is a plain lighter really enough?
Is a plain lighter really enough?
For small parts and thin sheet, yes, and our customers do it every day. For a thick or heavy part that soaks up a lot of heat, a $15 propane torch will be far more comfortable. We would rather tell you plainly.
Which metals does it work on?
Which metals does it work on?
Aluminum and aluminum alloys, copper, brass, zinc, cast iron and galvanized steel. You can also join two different metals, for example aluminum onto copper. On thick stainless steel the hold is more limited.
Do I have to buy flux or a cleaner?
Do I have to buy flux or a cleaner?
No. The flux is already inside the rod, so there is nothing to add. A quick sanding of the surface before you start is all it takes to get a good grip.
The rod balls up and will not flow, why?
The rod balls up and will not flow, why?
This is the most common mistake: you are heating the rod instead of the part. Play the flame over the metal around the area for ten to fifteen seconds, then touch the rod to the hot metal. It will flow into the joint on its own.
Does the joint actually hold?
Does the joint actually hold?
Yes, as long as you clean the surface first. Rust, paint and grease stop the alloy from gripping. This is low-temperature brazing, ideal for patching, sealing, reattaching and rejoining around the house. For a structural part under heavy load or constant vibration, call a professional.
My rods arrived snapped, is that normal?
My rods arrived snapped, is that normal?
Yes. The alloy is deliberately brittle when cold, and that is exactly what lets it melt so low. A rod that arrives in two pieces is used in exactly the same way and loses none of its properties.

I was able to join aluminum and copper pieces without any issues. The fusion happens quickly and the bond is really solid.
Tom L.
Verified Buyer
The big advantage is that you don't need to heat the metal until it's glowing white. It prevents thin parts from warping; the control is perfect.
Mark H.
Very surprised by its ability to bond different types of metals together. The low melting point allows you to work cleanly without damaging the base material.
Luke W.
Verified Buyer
Once the metal cools down, the joint is incredibly robust. I tested the strength by applying some force, and it didn't budge a bit.
Paul G.
I usually fix up old gardening tools. These rods penetrate cracks really well and give the metal a second life.
Ben T.
Verified Buyer
Clean result on a punched-through colander. The hole is sealed and water does not get past it at all.
Nathan E.
Rejoined the handle on my dutch oven with a kitchen lighter. Tidy finish, very happy with it.
Ian O.
Verified Buyer
Skeptical at first, convinced after three repairs around the house. Solid and genuinely simple.
Josh F.
Verified Buyer
Not perfect but far better than the glue I tried before. Cleaner finish and it actually lasts.
Mike S.
Perfect for the small everyday fixes.
Sam C.
Verified Buyer
Used it on a bike frame and on a gutter. The joint held after sanding and painting.
David M.
Holds well on aluminum, no complaints.
Alex B.
Verified Buyer
My zinc watering can had leaked for two years. Ten minutes and it is back in service.
Adam K.
Took one try to get the knack, then it flowed right into the joint every time.
Owen N.
Verified Buyer
I run a small maintenance crew and keep a pack in the van. Handy for the odd fix that does not justify dragging the welder out.
Chris R.
Verified Buyer
Good value and consistent results for small household repairs.
Ryan J.
Verified Buyer
Patched a trailer fender that I was about to scrap. Strong seam and easy to handle.
