Home improvement tool promising compact, one-handed spot welding for battery packs and thin metal sheets, ideal for workshop repairs and field jobs. Lightweight, precise control and a clear OLED status readout deliver confidence to hobbyists and technicians. Is the Awgem Battery Spot Welder the right choice for everyday battery maintenance and DIY pack building?
⚡ At a Glance
- • Welding Quality: Consistent, strong welds on 0.1–0.2mm nickel and thin stainless steel thanks to dual pulse output and adjustable power
- • Best for: DIY battery pack builders, repair technicians and hobbyists working with cylindrical lithium cells
- • Not ideal for: Heavy industrial welding or joining thick metal beyond thin sheets
Integrated power supply and welder pen enable compact one-handed use with an OLED that reports mode and welding progress. Ninety-nine adjustable gears plus auto and manual modes allow repeatable control while built-in protections reduce electrical risks.
Precise, repeatable welds – with 99 adjustable power levels
A 99-step power control lets users select very fine increments of welding energy, and dual pulse output helps control heat spread during each weld. Auto and manual modes allow either a single preset pulse or user-triggered timing for complex joints.
Fine power adjustment means cleaner joins on thin nickel strips and less risk of damaging cells, so battery tabs remain neat and reliable for pack assembly.
Portable, one-handed operation – thanks to integrated power and compact form
Power supply and pen are combined into a single unit weighing 140g and measuring 6.8in by 1.7in, with two top-mounted buttons for parameter changes. The design supports operation with one hand while the other stabilises the workpiece.
True one-handed welding makes field repairs and tight-spot jobs faster, and small size keeps the kit easy to carry between workshop and site.
Safer, ready-to-use kit – with OLED status and protective circuitry
OLED colour display shows mode, power, preheat status, time delay and welding progress, while circuitry includes protections against low voltage, overcurrent and overcharge. Supplied accessories include a spot welder pen, nickel sheet, gauze and a charging cable.
Clear on-screen feedback and safety protections reduce guesswork and help avoid electrical faults, while included parts allow immediate use straight from the box.
