Key Specifications

What Is the GLITTER Spot Welder 801D?

The GLITTER Spot Welder 801D is a compact capacitor pulse spot welder for battery pack assembly and repair. It sits above basic handheld welders because it gives you a bench setup, a rocker arm, a mobile welding pen, a foot pedal, and adjustable energy output.

Its main selling point is control. The 801D gives you 0 to 99T energy grades, AT automatic triggering, MT foot-pedal triggering, 0 to 20ms pulse time, and a 200 to 500ms preload delay. That range helps you tune welds for different strip thicknesses instead of guessing with one fixed output level.

The unit weighs 8.4 lb and measures 2.6 x 7.1 x 5 inches, so it fits on a small workbench. The aluminum alloy body helps with durability and heat dissipation, while the 360° movable base helps you position battery packs more comfortably.

Who Should Buy the GLITTER 801D?

Who It’s For

• DIY battery builders who assemble 18650 packs and need adjustable energy for nickel strip thicknesses from 0.05mm to 0.3mm.
• LiFePO4 users who need to weld aluminum-nickel composite strip up to 0.15mm on LFP battery aluminum electrodes.
• Small repair shops that want both a push-down rocker arm and a 73B mobile welding pen in one compact bench setup.

Who Should Skip It

• High-volume production users who need automated feed systems, fast cycle times, and industrial duty-cycle control.
• Casual users who only need one or two simple welds and do not want to test settings on scrap strip first.
• Beginners who do not have basic battery safety knowledge, because lithium cells need careful handling, insulation, and short-circuit protection.

Feature Deep Dive

Design and Build Quality

The 801D uses an aluminum alloy body with a compact 2.6 x 7.1 x 5 inch footprint. At 8.4 lb, it feels more like a small bench tool than a pocket welder, but you can still move it between work areas without a cart.

The 360° movable base gives you more freedom when you line up cells, strip, and electrodes. That matters when you work with uneven pack layouts or series connections where a fixed arm angle can make the job awkward.

The package includes the spot welder base, handle-push welding arm, 73B mobile welding pen, and foot pedal. No carrying case comes with the unit, so you should plan a clean storage spot for the welder, cables, pedal, and electrodes.

Performance and Welding Capabilities

The GLITTER Spot Welder 801D delivers 14.5kW pulse power and 290J peak welding energy. Retail listings also describe it with a 2,500A peak current claim, which places it well above many small handheld battery welders.

The listed welding range covers 0.05 to 0.3mm pure nickel strip on 18650 batteries and 0.1 to 0.4mm nickel-plated strip. It also supports 0.05 to 0.15mm aluminum-nickel composite sheet for LFP battery aluminum electrodes.

You still need to match the energy setting to your strip, cell type, and electrode pressure. Start on scrap strip, clean the electrode tips, and increase power gradually until the weld holds without burning or punching through the material.

User Experience and Controls

The control setup gives you 0 to 99T energy grades, AT mode, and MT mode. AT mode works well when you want repeatable auto-trigger welding, while MT mode lets you control each weld with the foot pedal.

The digital display shows the instantaneous current value during welding. That feedback helps you spot changes in contact pressure, dirty electrode tips, or weak connections before you ruin several cells in a row.

The 73SA down-pressing rocker arm supports stable bench welding, and the 73B mobile pen helps when the pack shape does not fit neatly under the arm. This dual-tool setup gives you more flexibility than a fixed-arm-only machine.

Power Input and Setup

The 801D supports AC 100 to 240V input at 50/60Hz, with a 5.8V DC output listed for welding. The adapter parameter is 15V and 2A to 3A max, so you should use the correct adapter and check the local plug and voltage before use.

GLITTER lists a 30 to 40 minute charging time before first use. That setup step matters because capacitor welders need stored energy ready before they deliver consistent pulses.

The 200 to 500ms preload delay helps the machine prepare before each weld. In real use, that delay can improve repeatability, but it also means the 801D will not feel like a fully automated production welder.

Battery and Material Compatibility

The 801D suits NiMH, NiCd, lithium-ion, lithium polymer, and rechargeable battery pack work when the tabs and strip fall within its listed welding range. It also supports battery pack repair, portable power source assembly, and small electronic device battery work.

For 18650 projects, the main advantage comes from the pure nickel and nickel-plated strip range. You can tune the 99 energy grades for thin tab work or thicker strip, then test pull strength before you build the full pack.

For LiFePO4 packs, the aluminum-nickel composite sheet range gives the 801D a useful role beyond basic 18650 builds. You should still confirm your strip material and thickness before you rely on the final welds.

How It Performs in Real Use

For 18650 Battery Pack Builds

On an 18650 pack, the 99T energy range gives you enough adjustment to work with both thin and thicker nickel strip. The foot pedal helps because you can hold the cell group and strip steady with both hands before triggering the weld.

For LiFePO4 Projects

For LiFePO4 work, the listed 0.05 to 0.15mm aluminum-nickel composite range makes the 801D more useful than many basic welders. You need careful setup because LFP battery terminals and composite strip can demand different pressure and timing than standard 18650 nickel strip.

For Small Repair Shops

In a small shop, the 73SA rocker arm gives you repeatability for simple rows, while the 73B mobile pen helps with awkward pack shapes. The 8.4 lb weight keeps the welder portable, but the lack of a case means you should store the accessories carefully.

For Long DIY Sessions

During longer sessions, the capacitor system gives stable pulse power, but your workflow still depends on setup quality. Clean electrodes, flat strip, steady pressure, and test welds matter as much as the 14.5kW power rating.

Pros and Cons

Is It Worth the Price?

The GLITTER 801D makes the most sense as a mid-range to advanced DIY battery spot welder. You get capacitor pulse welding, 14.5kW output, 99-step energy control, two trigger modes, and two welding tool styles in one kit.

That feature mix gives it strong value for the price if you build packs often or repair battery connections in a small shop. You pay for control and flexibility, not just raw output.

You get less value if you only need one simple repair or you do not want to learn proper welding setup. For frequent 18650 or LiFePO4 work, the 801D can be a worthwhile investment because it helps you make cleaner, repeatable welds after you dial in the settings.

How It Compares to Alternatives

If you want a simpler and cheaper GLITTER model, the GLITTER 801A gives you a lower-output option for lighter battery work. If you want more power from the same brand line, the GLITTER 801H sits higher with a stronger output class for more demanding projects.

Compared with SUNKKO 737G-style transformer welders, the 801D focuses on capacitor pulse control and a smaller bench footprint. The GLITTER 801D remains the better pick when you value compact size, 99-step control, and both rocker-arm and mobile-pen welding in one package.

Safety and Maintenance Tips

Spot welding battery cells carries real risk because lithium cells can short, vent, or catch fire if you handle them incorrectly. Wear safety goggles and gloves, keep flammable items away from the bench, and use a fire-resistant work surface.

Always check polarity, cell condition, insulation rings, and strip placement before each weld. Never weld damaged, swollen, or unknown cells, and do not skip a battery management system when your pack design requires one.

For maintenance, clean the electrode tips often and inspect cables before long sessions. Dirty tips reduce conductivity, create weak welds, and force you to raise the energy setting more than necessary.

Frequently Asked Questions

Does the GLITTER 801D work for 18650 battery packs?

Yes, the 801D targets 18650 battery pack assembly and repair. It supports pure nickel strip from 0.05 to 0.3mm and nickel-plated strip from 0.1 to 0.4mm on 18650 cells.

Can the GLITTER 801D weld pure nickel strip?

Yes, GLITTER lists pure nickel welding to 18650 batteries from 0.05 to 0.3mm. You should still test on scrap strip first because electrode pressure, strip quality, and energy level affect the final weld.

What is the difference between AT and MT mode?

AT mode triggers welding automatically and works well when you repeat the same weld many times. MT mode uses the foot pedal, which gives you more control during setup, testing, and tricky pack layouts.

Does the welder include a foot pedal and welding pen?

Yes, the listed kit includes a foot pedal, handle-push welding arm, spot welder base, and 73B mobile welding pen. That means you can use a fixed bench setup or a freehand pen depending on the battery layout.

Does the GLITTER 801D need charging before first use?

Yes, the manufacturer lists a 30 to 40 minute charging time before first use. This step lets the capacitor system reach the correct working state before you begin welding.

Is the GLITTER 801D good for beginners?

It can work for careful beginners, but it is not a no-skill tool. You need to understand battery safety, practice on scrap strip, clean the electrodes, and choose the correct energy setting before you weld real cells.

The Bottom Line

The GLITTER Spot Welder 801D earns an 8.4/10 because it gives you strong pulse output, 99-step control, AT/MT trigger modes, and both rocker-arm and mobile-pen welding. It is a smart buy for DIY battery builders and small-shop users who need controlled welds on 18650, LiFePO4, pure nickel, and composite strip work.

You should skip it if you need a fully automated production welder or a tool that needs no testing before use. For careful users who build packs regularly, the 801D offers a strong mix of power, portability, and control.
