SEQURE SQ-SW3 Spot Welder (SWP25 + WP30 EU Plug)

The SEQURE SQ-SW3 is a portable spot welder designed for FPV pilots and drone builders constructing custom 18650 or 21700 Li-ion packs for long-range cruising and cinelifter rigs. This complete kit includes the ergonomic SWP25 split welding pen for precise contact placement and a WP30 EU power adapter, allowing immediate bench use without requiring a separate high-discharge donor battery.

Key features

• Fuses 0.1mm to 0.2mm nickel strips for secure, low-resistance battery assembly.
• 1.8-inch colour TFT display provides real-time readouts of input voltage, temperature, and weld parameters.
• Fully adjustable pulse duration and pulse count to dial in exact weld penetration for different nickel thicknesses.
• Selectable auto and manual trigger modes with an adjustable trigger delay of 0.5 to 3 seconds.
• Built-in low-voltage warning and over-temperature safety protections.

Specifications

• Input voltage: 10-14V DC
• Display: 1.8-inch colour TFT
• Supported nickel thickness: 0.1-0.2mm
• Power connector: XT90
• Included welding pen: SWP25 (Split type)
• Included power supply: WP30 (EU Plug)

When operating the welder in the field without the WP30 adapter, power it via the XT90 port using a high-discharge 3S LiPo (5000mAh, 60C minimum) or a standard 12V lead-acid car battery. Do not use 4S or higher LiPo packs, as exceeding 14V will permanently damage the unit.
