Hello Rod

The Precison TIG's transformer and choke assemblies are all aluminum wound. I wouldn't be too concerned about this since most
static (welders you plug in to electrical power ) are now wound with aluminum windings. The "problems" associated with aluminum
windings are actually in their connections , similar to aluminum house wiring. This is taken care of in manufacturing by welding the
windings, or using "Al Cu plate"...explosion bonded aluminum and copper), or most commonly proper connection preparation

It is a fallacy that copper windings "weld better" or have a better arc. The only time this has been proven to be true is rotating equipment ( generator welders )
Most of even the top of the line power supplies on the market are now aluminum windings. The expection is when there is not enough physical
room for aluminum ( al windings are thicker ) . This is the case for some "tri voltage" welders that need 208/230/460/575 windings

The best test for the Precision TIG 275 is you weld with it. I assure you the arc starts are much nicer than the older Square Wave and current Syncro wave TIG units

Visit Lincoln's web sight and read the article on the Micro Start Technology
