TECNA 8213D Press / Projection-Type Spot Welder
125 kVA – Single-Phase AC Press / Projection-Type Spot Welder from TECNADirect.com
The TECNA 8213D is a versatile single-phase AC press-type spot welder with TE550 Weld Controls. Part of the 821X series from TECNADirect.com, this pedestal welder is designed to bring you the highest quality of work. The TECNA 8211D press-type welder is air-operated and water-cooled, and available in dual voltage 220v/440v.
Press / projection-type spot welders from TECNA feature a stationary, ergonomic frame. Controls have been positioned frontally, allowing the press operator to view the welding data during the working cycle. The pneumatic commands and the compressed air pressure gauge have been placed at the top for easier adjustment and reading.
