Thanks a lot Fang sama 555555

There are many providers in the market like Branson, Dukane, Hermann

I personally use a Branson X2000 machine but the brand and size depends on your type of application mostly.

For small applications, thereare even hand welding (Shaped like drilling machines ) and for big scale production, you can choose a bigger machines.
