SDT20 Head spot welders
SDT20 head spot welder with pneumatic operation and 20KVA power at 50%.
The SDT20 head spot welder with electropneumatic operation ensures excellent quality of welding of cross-wires and different types of profiles. The SDT20 head spot welder is manufactured with 400V primary nominal voltage or 220V on demand. It can be equipped with a heading to avoid porosity on the welded profile. The head spot welder is completely water cooled and managed by MICRO8, the digital microprocessor weld control board which ensures good welding results.
