The 5000W high-power battery spot welder has good performance and long service life. It can provide strong power and improve work efficiency. The spot welder controls two ultra-high-speed batteries, accurately outputs pulse energy through the program of the built-in single-chip microcomputer, and generates high temperature in a short time. After rapid cooling, the nickel strip and the battery are welded locally. [Two Automatic and Pedal Modes]: Different from traditional local welding machines, this product is equipped with an automatic switching head and a foot-operated spot welding plate, which supports automatic and manual pedal modes. It can be replaced at any time according to your operation needs. [1-9 Level Knob Adjustment]: The mini spot welder is designed with 9-level output power adjustment, you can adjust the output power from 0-800A by turning the knob, the larger the value, the higher the output. [LCD display] The battery voltage level is a key factor affecting the spot welding effect. The screen of our spot welder can display the internal voltage of the product in real time, which is convenient to check and charge in time. It should be fully when using for the first time, please charge when the screen voltage is lower than 7.3V. [Easy to Use]: This mini spot welding equipment is mini and light, saving space in the home, you can and quickly transport the spot welding machine to different working positions. Spot welders are equipped with soldering pens that are electrically conductive and have low contact resistance. The welding needle of the adjustable spot welding machine can be removed and replaced, installed and operated. [Warm Tips for Novices]: After receiving the product, please charge it first and practice several times to find the appropriate spot welding strength, this is a small battery packwelding machine, suitable for both beginners and professional welders. [WIDE APPLICATIONS]: The spot welder with output power can be used to connect nickel strips of 18650 lithium batteries, or spot weld iron plates and stainless steel plates. It is also suitable for fast welding 0.1-0.15mm nickel-plated steel plate and 0.1mm pure nickel plate. It is very suitable for making battery packs and engineering repairs.
