    Help with TIG welder decision

    After wandering around a couple of welding shops I am confused about a TIG welder. I have a Maxstar 200 STR which is basically a portable TIG DC only machine and I want to get something that will do aluminum as well as steel. I would be willing to spend in the $2000 to $2500 range or more if necessary. The unit will be shop bound. Some of the people seem to push Miller and some Lincoln but the people say that the amperage is misleading because of the low duty cycle. I do mostly lighter things but it is nice to be able to weld heavier stuff occasionally.

    Thanks,

    Jim

    Lift arc question

    I have a foot pedal on the unit. The local guy told me that I should advance the foot pedal when using the lift arc. Can anyone give me more specific instructions than what is in the manual.

    Thanks,

    Jim

    lift arc is good if for some reason you don't have a remote or the ability to use one.

    For those who are more experienced, how do you rate the lift-arc versus the high frequency start? I have been taking a TIG class at a local community college and using a big Miller water cooled tig and so the Maxstar and the older Syncrowave are my only reference. Somehow I keep thinking that I am going to ruin the Tungsten when using the lift arc. Also, the manual doesn't tell much about what amps you use when starting the lift arc.

    "Lift-Arc™ allows the tungsten to be placed in direct contact
    with the metal to be welded. As the tungsten is lifted off the
    part, the arc is established. This is sometimes referred to as
    touch start. Little if any chance of contamination is possible
    due to special power source circuitry. When the Lift-Arc switch
    is activated, lower power level is supplied to the tungsten
    electrode. This low power allows some preheating of the
    tungsten when it is in initial contact with the part. Remember
    hot tungsten is a good emitter of electrons. This power level
    is low enough not to overheat the tungsten or melt the work
    thus eliminating the possibility of contamination. Once the
    arc is established the power source circuitry switches from
    the Lift-Arc mode to the weld power mode and welding can
    commence. Figure 2.34 illustrates the proper techniques to
    use with the Lift-Arc starting method.

    i got the dynasty dx for aluminum and its the best
    but dont forget its a great stick welder to i use it on the
    road all the time for steel and stainless stick, 2 leads a 50' #10 ex.
    cord a couple addaptors for 110 and 220 and some rods
    and it all fit in the front seat of the truck
    you will not be sorry with this welder got mine at cyberweld .com
    no shipping or tax

    The inverter welder like the Dynasty is the way to go. The Syncrowave doesn't have adjustable AC frequency or a pulser (10pps is hardly a pulser compared to the 250 pps on the Dynasty 200DX). The power of blue. Dream it, weld it.
