Transformer steel spotter for straightening and pulling work that calls for power. Depending on the control fitted, it offers three power ranges (high, medium, low) with time adjustment, or stepless adjustment for finer repairs. Microprocessor control, an improved transformer and precise weld time regulation give consistent, energy-efficient work. Mounted on a trolley, it covers every welding function used in dent repair.
