Helvi Inverter DC ARC / TIG Welder

Inverter power sources designed to meet the needs of the most demanding users. Easy-to-use both in STICK welding and TIG welding with HF start. All main welding parameters can be adjusted by the user : in TIG welding, 2 stroke or 4 stroke mode, pre-gas, up-slope time, pulsation frequency, basic current, down-slope time, crater filler current, post-gas : in STICK welding Hot Start and Arc Force are adjustable.

Three phases welding inverters designed to work with unstable supply voltages caused by the use of power generators and long connection lines, designed to meet the requirements of even the most demanding user with a wide current range and a high duty cycle. Excellent welding features guaranteed with all types of commercial electrodes (rutile, basic, stainless steel) due to the possibility to setup Arc Force and Hot Start values. The models 300C can also weld cellulosic and aluminium electrodes. Equipped with special features controlling excess input voltage, overheating and electrode sticking, functions which protect against instable generators even in the harshest working conditions. The TIG/MMA switch also enables use for TIG Lift Arc welding. Equipped with digital display to show welding current, welding voltage and other parameters (hot start and arc force). The generator is fitted with a VRD, which allows to work even in hazard environments. The VRD function can be switched on or off as required. All of them may be used with remote control

Standart accessories:
Earth clamp with cable 3M

Optional accessories:
Argon regulator, TIG torch (Air cooled or Water cooled),
Electrode holder, Water cooling unit, Remote control

They are equipped with digital ammeter which shows welding current and preset parameters.

Welding inverters designed to work with unstable supply voltages caused by the use of power units and long connection lines. Microprocessor controlled, they provide excellent MMA welding performance with most types of commercial electrodes and TIG welding with HF or LIFT arc ignition MMA: arc force and hot start preset to optimum for GLOBUS 225 HF and adjustable for COMPACT 305 HF. TIG values: 2-stroke, 4-stroke, 2-stroke pulsated or 4-stroke pulsated. Down Slope and Post Gas are adjustable. COMPACT 305HF model is fitted with a digital instrument panel which displays both welding current and voltage, all welding parameters are adjustable from the front panel. The unit is fitted with VRD function, which allows the user to work safely even in hazard environments. The VRD function can be switched on or off as required. It can also be used with a remote control or foot pedal control.
