1.Why laswer welding BETTER than threaded holes?
- high current discharge 280A→screw expands after overheated→screw loosens easily→larger resistance-smaller discharge
- longtime using→screw interface rusted or oxidized→larger resistance→smaller discharge
- high current discharge 280A →1 threaded hole can't delivery 280A-→smaller discharge
- high current discharge 280A→screw expands after over heated→screw loosens easily-larger resistance→smaller discharge
- 2 threaded holes can halve the discharge current and heat
