TECNA 8208D Press / Projection-Type Welder

100 kVA Single-Phase AC Press / Projection-Type Welder from TECNADirect.com

The TECNA 8208D is a 100 kVA, single-phase AC press / projection-type welder is a versatile machine with TE550 Weld Controls. Pedestal welders from TECNADirect.com, including the 8208D are designed to bring you the highest quality of work and exceptional performance.

Press / projection-type welders from TECNADirect.com 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.
