New MMA/TIG welder from GYS

Professional 250A portable welding inverter capable of welding cellulosic welding electrodes

GYSMI 253 CEL is a new professional 400V three-phase 250A MMA/TIG, portable welding inverter from GYS Ltd that can weld using a wide power supply source ranging from 340-460V, even when being used with long power supply cables.

It is rated 250A @ 100% duty cycle and with a Uocv start voltage of 100V it is capable of welding cellulosic welding electrodes ranging from 1.6–5mm in diameter in addition to welding mild steel, stainless steel, cast iron and aluminium.

In MMA mode, in addition to an adjustable arc force producing good penetration and giving an anti-stick function, it also features an adjustable ‘hot start’ function incorporating ‘low hot start’ for welding thin-gauge materials and a ‘high hot start’ for welding materials with dirt ingression or that include oxidized parts. The GYSMi 253CEL also features a robust and splash-proof (IP23) casing and is designed for welding in boiler making, pipework and general-purpose heavy-duty welding applications.

It can be used to weld most materials using the TIG welding mode with the exception of aluminium and alloy materials.

In the TIG welding mode the GYSMI 253 CEL features easy starting using the TIG lift arc function, preventing tungsten inclusions and radio electrical disturbance. Other features include automatic and adjustable ‘arc down’ slope which makes for a smooth weld finish with no crater, whilst the automatic torch release after welding is easy.

The unit has anti-dust ventilation from back to the front of the unit in order to minimize dust ingression into the machine’s electronic components.
