Re: welding and UN-welding


<x-flowed>    M.I.G. common reference MIG = Metalic Inert Gas. Don't let any sales 
brochure fool you, there is no such thing as a "gasless" MIG. The gas shield 
prevents oxygen from getting near the weld puddle and leaves no slag to 
remove like ARC welding and wire feed does.
    That said, I use a Hobart Handler 110 for sheet metal, it only requires 
a 110 volt 20 amp circuit, I take this one to the jeep races because I can 
run it with the generator on the motorhome. Yes it only has a 10% duty cycle 
(12 seconds of welding for every 2 minutes the machine is on) but welding 
sheet metal is just a series of tack welds anyway. There are larger and more 
robust(and more expensive) wirefeed/MIG units out there, but as a hobbiest I 
havent found a better value.
    This machine is very portable and is convertable. In the MIG 
configuration with the gas shield on(CO2/Argon) I run solid core wire and 
get nice clean welds on steel. Change the gas bottle to straight Argon, 
change the spool of wire, change the liner and weld 6061 Aluminum.
    Going to the races? Remove the gas line, change the spool to "flux core" 
wire and I've got a wire feed welder that I can run with the motorhome 
generator. This unit has kept many people racing through the weekend after 
they've broken on Saturday morning.
    I have several welders and if I were forced to go down to just 2 at the 
house they would be my Miller AC/DC stick and the little Hobart Handler 110.
Just my personal experience...

you want to go with, you want to make sure
that it is not one of those little ones that keep overheating every five
minutes and cutting out.
