Description
Intelligent Spot Welder Machine for Batteries 100-900A Adjustable Current & 6.5-16V Wide Voltage, Anti-Burnout Protection, DHJ-02B1. This spot welder is suitable for securely welding various cylindrical lithium ion batteries (e. g., 18650, 26650, 32650), Ni MH, and Ni Cd batteries. It supports the use of nickel strips with thicknesses from 0. 1mm to 0. 3mm. 2. An integrated intelligent logic control chip automatically calculates the battery power parameters. This smart regulation is designed to prevent MOSFET burnout ("blowouts") during operation with different battery types. 3.

Works great, easy assembly and no issues!
Using the weedeater for edging was too hard, so I purchased this. It works great! It was easy to assemble and easy to use. My lines are perfect, but the size, durability, and power of this gem get the job done, and it's lightweight enough that I can easily maneuver it around the yard. I chose a corded one so I don't have to deal with battery life or charging.

Great Edger for the Price
I’ve had no issues at all with this lawn edger. For the price point and the amount of edging I need to do, it works great. It has plenty of power and gets the job done cleanly. Just make sure you have a long enough extension cord for your yard or projects. Overall, no complaints—solid product and an easy 5 stars from me.

It actually does the job pretty well
Style: Lawn Edger/Tool Only
I floundered around for a few minutes, then figured out how to use it, and then made pretty good progress on my overgrown sidewalks. Yes, it uses up batteries but that's because it actually has enough power to do the job, unlike many "homeowner" tools. The handle is long enough so I'm not painfully bent over while using the tool, and it feels solid and stable. One thing I really appreciated is that it doesn't have a typical pointless, awkward "safety" interlock button that you're supposed to keep mashed down with your thumb the whole time - it's a comfortable one-finger trigger.
Another good 20v tool from Worx. I'm "in".

Works great!
Style: Lawn Edger/Tool Only
Works great and uses the same batteries that we already had from other works equipment. I do wish the pole was longer.
