Frequently Asked Questions
Can It Weld Through Painted or Rusty Surfaces Without Prep?
No; it struggles to weld reliably through painted or rusty surfaces without surface preparation. The reviewer notes welding efficiency drops and recommends proper surface preparation for liberation from flawed bonds, ensuring consistent, durable stud welds.
