Heltec 73B Professional Spot Welding Pen: Redefine Your Battery Welding Experience
In the field of battery welding, “precision, efficiency, and safety” are never trade-offs—they are the standard of the Heltec 73B Spot Welding Pen. From R&D to mass production, we’ve condensed industrial-grade technology into this pen to create an ultimate welding solution for every quality-driven user.
Why Choose Heltec 73B?
Tired of spot welding tools that are either cumbersome to operate or underperforming? The Heltec 73B breaks the compromise with four core advantages:
-
Ultra-Simple Operation: Say goodbye to complicated external foot pedal switches. Weld with a gentle press, easily operated with one hand.
-
Superior Performance: With an ultra-low resistance of 0.747mΩ, its conductivity is nearly 50% higher than ordinary welding pens. It delivers stronger welding current, and the weld spot firmness is maximized (the pulling force of a 0.3mm nickel strip weld spot reaches 2.66KG).
-
Safety First: The built-in indicator light real-time prompts the welding status. The fully enclosed shell design eliminates the risk of exposed parts, allowing even beginners to operate with peace of mind.
-
Wide Compatibility: It can easily weld from 18650 to 32650 lithium batteries, from 0.1mm to 0.3mm nickel strips, and even aluminum-nickel composite strips. It is also compatible with U-shaped and circular interfaces of mainstream spot welding machines in the market.
Technical Details: Every Detail is Designed for “Better Welding”
1. Humanized Operation Design
-
Adaptive Pressure Adjustment: Knob-type pressure control, with a maximum welding pressure of 1200g and a minimum of 600g. It handles everything from 0.1mm thin nickel strips to 0.3mm thick nickel strips with ease.
-
Adjustable Welding Needle Distance: The distance of the welding needles can be adjusted from 3mm to 7mm, suitable for various sizes of lithium batteries such as 18650, 26650, and 32650.
-
Removable Welding Needles: The welding needles can be removed and replaced, ensuring precise weld spots and enabling recycling for cost savings.
2. Unmatched Conductivity & Weld Strength
-
Low Resistance Advantage: Compared to ordinary welding pens (1.455mΩ), the Heltec 73B’s 0.747mΩ low resistance ensures less energy loss and more stable current output.
-
Industry-Leading Weld Spot Pulling Force: When welding 0.3mm nickel strips on 18650 lithium batteries, the weld spot pulling force reaches 2.66KG, guaranteeing long-term connection reliability.
3. Versatile Welding Applications
It can handle a wide range of materials and scenarios:
-
Lithium battery packs (lithium iron phosphate, lithium polymer, etc.)
-
Circuit boards (including touchpad circuit boards, handwritten boards)
-
Various metals (nickel-copper-zinc alloy, titanium, brass, etc.)
Special materials (0.45mm aluminum-nickel composite strips) III. A Leap in Spot Welding Pen Evolution
The Heltec 73B represents the cutting-edge of spot welding pen technology:
-
Outdated Generations: Earlier designs were either separate and complicated (requiring two hands) or integrated but bulky and hard to use.
3rd Generation Innovation: The Heltec 73B features internal switches and high adjustability. It is lightweight yet powerful, marking a new success in the welding pen industry. Don’t Settle for Less—Choose Heltec 73B Today
