The Castolin Castotig 3002W is a liquid cooled TIG AC/DC power source, built on the base of the Fronius MagicWave 3000, for a 400 V supply. It gives 300 A at a 65% duty cycle and 260 A under a continuous load of 100%, and you set the current from 3 A to 300 A.
What this machine is for
A setting from 3 A makes this source a machine for very thin parts: sheet below a millimetre, thin walled tubes, the repair of edges and small parts of acid resistant steel. The upper value of 300 A is left for thicker sections and aluminium profiles. At 260 A the source works without a break, with no stops for cooling.
You take alternating current for aluminium and its alloys, because the positive half wave tears the layer of aluminium oxide from the pool. Direct current serves mild steel, acid resistant steel, copper, nickel and titanium, with a focused arc and a narrow heat affected zone. The foot pedal for current control changes the current during the run without lifting the torch, which helps when you fill the crater and on a changing thickness.
Features and equipment
- TIG AC/DC source for 300 A at a 65% duty cycle and 260 A in continuous work at 100%.
- Foot pedal for current control: you change the current with your foot while welding.
- An original TIG torch 4 m long.

What to watch out for
The supply is a 400 V mains and a three phase circuit, and the size of the fuse you settle with an electrician. The torch is 4 m long, so on a larger part the machine has to be moved. The cooler needs fluid with protection against freezing, so check the level, the flow and the seals at the quick couplings before the first arc. On alternating current the tungsten electrode wears faster, so keep a stock of electrodes and collets. The record gives no weight and no dimensions, so plan the transport in advance.
