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.

Excellent pans
Color: Linen Gray
Ceramic coating, aluminum body with steel plate on the bottom for induction cooking. Used these on an induction hot plate and they worked better than the stainless steel pans I had tried before. They have a nice heft, without being heavy. Made in Luxembourg according to the tag on the bottom. Very good looking pans.

Save your money! You get what you pay for!
Color: Linen Gray
Looks great and weighted good. No metal utensils or excessively high heat and these only lasted a month before the non stick ceramic coating either chipped off or was no longer non stick. Save your money. You get what you pay for. Save up for a set that will last you. I will not be buying these again nor recommend anyone else buy.

Love it!
Color: Ivory, Color: Ivory
When my daughter moved ..I gave her my 12 piece set of pots and pans. Got this 8 piece set. I don't need much. This set is amazing! I wish it came in pink. It's truly nonstick...try eggs with cheese...you will see. Clean up is amazingly easy. They look nice and are well made. The tops have a vent hole so stuff doesn't boil over. Love that! These will last for more years than I have left. Also...they store quite easily...doesn't take up much room.

Good value, good quality, basic set of non-nonstick ceramic coated cookware
Color: Linen Gray
Really like this set! Bought when on sale, good value for the set. Items arrived nicely packed. Wanted to buy beige but sold out, so got light gray, which looks very nice as well. Followed instructions to prep the pieces with oil. Been using on stove top almost everyday. Haven’t tried putting in oven yet. Non-stick but work very well on browning: chicken wings, shrimps, meat, onions….. After cooking, let them cool completely, then very easy to clean with soft sponge. Just have to use silicone cookware to avoid scratching.
