    Default What kind of welder?

    Hey guys Iím looking at getting a ac/dc welder. Iím looking at Everlast, Eastwood, Ahp alpha 200 and others. Budget is under $1000

    My question is what are you guys set your amps too when welding tabs 1/4Ē or less to the frame?
    Iím just curious cause I see some guys set thereís at 100amps and weld tabs but there welders are 200amp machines.

    I see a lot of people are running 200amp welders.

    I have a 220v in my garage so I could get full power out the welders but I have been looking at the everlast 185 ac/dc tig and Iím wondering if that will be enough for the job or if that is even overkill on amps I need?

    I also am wondering if I’ll have enough to do aluminum stuff

    Compare duty cycles...100 percent means plug it in and burn forever, 10 percent means turn it on and use it for ten minutes, leave it running 90 minutes and it will be cool enough for another 10.
    200 will do some smaller aluminum. Plenty of people have strong opinions on welders, but to me the duty cycle is one of the most important specs after amps.

    I've had an everlast 255 since 2011. It died on me in 2015, everlast fixed it free of charge and upgraded my torch to boot. Has welded everything I can throw at it and customer service has been great.

    To answer your questions for a 1/4 fillet weld Miller recommends the following:

ID:	102826

    Tungsten Electrode Diameter:
    1/8" (3.2 mm)

    Historically, 2% thoriated tungsten (red band) prepared with a pointed end has been used. Today more people are switching to 2% ceriated or 1.5% lanthanum (gold band) due to their superior performance in most applications

    Torch Cup Orifice Diameter:
    1/2" (12.7 mm)

    Use ceramic cup when welding with less than 250 amps. Use water-cooled torch when welding with more than 200 amps.

    Filler Metal Diameter:
    3/16" (4.8 mm)

    Polarity:
    DCEN (straight polarity)

    Amperage Range:
    250-325

    For mild steel, increase amperage 10%.

    Gas:
    Argon

    Gas Flow Rate:
    13 cfh or 20 psi


    Welding Speed:
    5 inches per minute

    I have the Alpha Tig 200..

    I'm new to tig welding, but I love it so far. I think it was an excellent value.

    Thank you all. Lots of good information! I ended up going with the AHP Alpha 201 XD Tig.

    I bought the HTP 221 Invertig. I really like it.I bought it to do aluminum and so far so good. Tig welding aluminum with an adjustable machine is way different than using the old Hi-Freq box.
