S3 Integrated Copper Spot Welding Pen Built-in Spring Pressure Adjustable Screw

Features:
The main copper rod is made of 4*15MM copper and the spot welding clipheadadopts 5*20mm copper to enhance the heat dissipation capacity, whichensures that there is no temperature rise and heat in large batch spot welding.
The conductivity of copper is 3-5 times that of brass, with larger spot weldingpower, and it is more stable.
The outshell of handle is made from pom material, with high hardness, finewear resistance, anti-broken and practical.
There are some antiskid textures one the both side of handle, simple but withfine antislip effect.
Built-in double springs in the handle, and equipped with pressure adjustablescrews, anti-clockwise rotation to increase pressure, clockwise rotation toreduce pressure.
Built-in trigger switch, one-handed operation, no foot pedal.
Supporting clamp 1.5mm and 3mm solderpins, just detach the screw rorationcliphead to change.
