Description
The CAT DZ 251 ST welding machine with a detachable torch features a hot start function, essential during power fluctuations and when working on rusted materials. Integrated cooling fans bring the unit down to room temperature. IP21S protection makes the housing resistant to dust settling and negative effects of water splashes.
The CAT DZ 251 ST welding machine is equipped with a digital display showing current operating processes. The protection system automatically shuts down the device to prevent overload. An internally located spool provides added convenience during transportation.
