Most Frequently Asked Questions
A beginner, trained welder, and hobbyist have their own questions. We will be discussing the few very common here.
1. How does a battery spot welder work?
The heat and pressure application is the cornerstone of its working. Copper alloy-made electrode transmits current and makes the metal melt and fuse.
The current is staying away when the pressure solidifies the weld to create the joint.
2. How much is the maximum temperature in the battery spot welder?
The maximum temperature with welding time and welding current can be attained up to 2550 Degrees F.
3. What is the voltage level required for battery spot welding?
For regular small welding 50V, AC is needed while 80V AC is required for special needs.
4. Can a battery spot welder shock me?
They can do a small extent and that too very rarely. If we are careful the chances are minimal and it is really uncommon to have a lethal shock.
5. Is there any metal that can not be battery spot welded?
Most of the battery spot welding is suitable for it except zinc silver, and lead.
6. Can we solder the battery directly?
This is not a great idea, I may damage the seal. It can be done on battery at one end.
7. Can one use a tap as a substitute for soldering?
No, you can use metallic glue, not any tape.
