SEQURE SQ-SW3 Capacitor Energy Storage Spot Welder

Meet the SEQURE SQ-SW3—a capacitor energy storage spot welder that doesn't mess around. With a peak output of 2500A and support for fast, slow, and battery charging, this compact welder is built for serious DIYers, battery builders, and anyone who knows the thrill of fusing metal with precision.

Housed in a sleek all-metal aluminum body that doubles as a heat-dissipating exosuit, the SQ-SW3 is equipped with a 1.8" HD color screen, dual-language support, and two trigger modes (auto or manual, depending on your mood or caffeine level).

Whether you're spot welding nickel-plated strips, pure nickel up to 0.3mm thick, or copper sheets up to 0.2mm, this machine delivers power reliably without melting your pins into a sticky mess. And yes, the welding pins are aluminum oxide copper—because durability shouldn't be optional.

With both split (SWP25) and integrated (WP30) welding handles made from ultra-flexible, nickel-plated copper, you'll enjoy low resistance, high conductivity, and the soft touch of a welder that cares.

WHAT I LEARNED
Color: U.S.A, Size: Medium
i AM NOT SURE THAT 4 STARS IS A FAIR SCORE, MY DOG IS AN AGGRESSIVE CHEWER, NEEDLESS TO SAY WITHIN 2 DAYS ALL THE TABS WERE OFF, BUT THERE WERE NUBS LEFT AND SHE CAN USE THAT. HERE IS A WHAT NOT TO DO, BRING IT TO THE DOG PARK, THEY ALL HAVE A BLAST BUT IF YOUR A BULLY/PIT MIX AND DECIDE TO SINK THEIR TEETH INTO IT, IT DOES DEFLAT. LESSONS LEARNED STILL A FUN TOY.

Sturdy ball with pump
Color: Black/White, Size: Medium
Thick material so it won't pop so easy. Comes with a hand pump and 2 ball needles. Tabs for the dog to carry in his mouth. Although my dog bites the whole thing to carry. Savage loves it!

Durable and fun
Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug
This is a cool toy. My dog took to it right away. It tosses great. I like that you can play a little tugging along with fetch. We mainly use it outdoors. It feels very strong and durable. For size reference my dog is a mini golden doodle and weighs about 30lbs.

Great toy!
Size: Medium, Style: Ultra Tug
We have a 1 yr old rescue (German shepherd mix) and she didnt really know how to play with humans, she was scared of everything. We got this toy to help us teach her how to play fetch and tug of war and it really helped her come out of her shell. She loves this toy! It is very durable and fun to throw. Just enough rope to tug with her and doesn't come apart like other rope material. We got medium size and prob buy another one.

Durable
Size: Small, Style: Ultra Duo Tug
Well, our dogs didn't end up playing tug with each other, but they love the toy anyway and it still looks pretty good after a month. That doesn't sound like much, but they both love to chew and destroy rubber and they're ridiculously good at it. They also really like chewing the strap between the two balls, which is still in surprisingly good condition. Most "indestructible" toys are toast within the hour. Well worth the money. Plus, the unpredictable bounce when thrown keeps the dogs busy.
