I am curious if your 150A welder can be used as a TIG welding power source? Since it is 100% duty cycle, and high frequency, I figure it can.

You are correct!

It's possible to do so -- using your existing torch -- requiring only a ZENA TIG adapter attachment (model PCIM) to interface your TIG torch to the ZENA system.

Two different types of foot control mechanism are available with our TIG adapters.

Note however, that the ZENA welder does not include a sparking system to facilitate TIG arc starting and, therefore, your TIG arc must be started by scratching. Normal care not to stick the TIG electrode to the material and contaminate your weld joint is required. Further, the output of the ZENA power generator is DC not AC so AC TIG welding is not possible -- only DC TIG.

DC TIG welding is not recommended for welding thin aluminum. DC is perfect for TIG welding other materials. But, going strictly "by the book", AC should be used for TIG welding aluminum, not DC.

With this said, we have had customers report that they have achieved good results welding aluminum, however, we can not guarantee that this will hold for all cases.
