Why didn't you used 10mm dc single core insulated cable with more of 5 or 6 turns of each transformer then it could stick hard.. thanks good video keep making good videos
purpose of spot welding for batteries is to PREVENT overheating (when they, for example, soldered with tin battery is overheating and taking damage from it). at this video you can see how DO NOT PREVENT overheating. spot welding should be performed with short and hard touches, one in attempt, and battery should left to cool down for a while. IMHO.
I totally agree, this device definitely heats up batteries too much 1v is totally not enough for those thin wires. + Using cheap spot welding timer makes things a lot easier and safer One that I made a long time ago has 1.4v with really thick wires directly coming from transformer. And It still needs to have 7x20ms time, which is a lot in my opinion. You need to have 2-5v voltage (with 1200w transformer) with dual pulse control to have it make proper welds on batteries.

Little Devil, I noticed that the secondary windings are crossed (the left transformer's left side wire to the left post and the right transformer's left wire to the right post). I believe that this would create an out of phase condition weakening the effect of the AC sine wave. If you switch the secondary winding on one of the transformer to the other post (both left secondary wires to left post) you will have both the transformers in phase, more than doubling the speed and strength of the weld.
If you had wired the 2 transformers in series then it would act as one transformer having only one sine wave with double the voltage and half the wattage coming out. You would still have to pay attention to the wring connections to have the desired voltage. With 2 transformers in parallel you have 2 sine waves to deal with. If the windings or the connections of 2 AC transformer are wired different then the peak (+ voltage) and the trough (- voltage) of the AC current are not the same at the same time (in phase). Even the directions of the windings can have an effect. The further out of phase (out of alignment one sine wave is to the other) the more one wave cancels out the other. If the out of phase sine wave (the cosine) is 180 degrees out of phase than the result can be a complete cancellation of each other. Remember that transformers that appear to be the same (from the same manufacturers with the same specs) will still have some variances.
I just reviewed the video and noticed at time line 1:56 (paused) that the wires to the secondary windings are also crossed. Since both the wires to the primary and the secondary are crossed the effect is canceled out. This would make the 2 transformers seem to be wire correctly in a parallel fashion. How ever, this still leaves the magnetic flux flowing the opposite directions in the transformers. The primary windings should be wound the same in both transformers, but the AC input is wired to opposing tabs, leaving the flux flowing in the opposite directions within the transformers. If the flux was flowing the same directions it would improve the end results.

I take the same view as the previous speakers
You are correct. He does not have enough power flowing to the work. He also needs to rewire the transformers correctly.
I totally agree, welding time should be around 0.1 second or preferably even less.
You need very high current (at low voltage).

You can get more current if you remove the metal shunts that sit on top of the primary winding.

I think better whould be to connect secondary windings in series and "dobule" voltage than amps, less power loss on cables
You need very high current in order to weld, many hundreds of Amps.
This can only be accomplished by converting to low voltage.
