the painted version is mig welded most likely with a robot or someone that has did that weld about a thousnad times and has gotten very good at those passes.

I think they look a little cold.

The original welds looks like a robotic MIG weld, with wire feed and torch speed set so that the bead looks like a hot glue joint. Cold.

If the weld was a little cold the weld would not be nice and smooth. I would say robotic-mig using a spray arc method.

Oh, I get ya. Cold as in not much base penetration. Not that the bead wasn't nice and fluid.

Someone posted up a pic of a 1150GS rear subframe with one of the passenger peg hoops torn off at the weld. It sort of looked like it was hot glued in place. The welds on that rack have that typical BMW appearance.

When a weld is cold you wont get much penetration an the weld just lays on top of the metal and it wont be the least bit smooth.

thin wall means they are running not really cold just low volts maybe even pulse which would acount for zero spatter.

Blowing through means scrap or hand triggering to fill and then grinding which is extra labor not accounted for.

Found a local package deal for a Hobart 140 with H-10 gun, cart, bottle of Argon, hood, magnets, spools, etc for $325. Want to learn to weld: opinions on this unit, will I outgrow it quickly, etc? Neighbor has offered to help me learn the ropes, and says I should jump on this deal. What sayeth the asylum?

Thanks,

EDIT: It looks like this is the deal you are speaking of....http://ocala.craigslist.org/tls/2121159254.html Jump on it while you have the chance....

Sounds like a very good deal to me if the unit is in good condition. The only thing false I see in the ad is that seller states that it is "exact duplicate of a Miller 140" which is a false statement. The Miller has "Autoset" function.

Some things I would ask would be the following;
  1. What size cylinder is it? Ideal if it is 80C.F. or bigger.
  2. What is the cylinder filled with? Ideally it should be a 75/25 mix of Argon/CO2
Both 1 & 2 above would not be deal breakers for the price, just questions I would bring up.

In my opinion if you are just learning you will not outgrow this unit quickly. When you do outgrow it, you could sell the 140 and step up to a 200A model and not take much of a loss (if any at all).

FWIW..... I have a Miller 135 (very similar unit) and love it. The 120V models are very versatile for the home hobbyist and great to learn on. I have about $400 in mine including cylinder.

too good to be true?

Mig for home use. Especially mc fab projects, so brackets, aux tanks etc. Wadda ya think? Seems like the cheapest way to weld alum.

http://www.amazon.com/Clarke-WE6441-.../dp/B000RH6JBA

Seems like all it needs is a gas regulator, 30-40$ Can't find any reviews on it.

The add states "Fluxcore" mig. I would doubt that this machine is capable of using a shield gas or welding alum.

I'd steer clear of it. With a 40% duty cycle at 60 amps, your probably going to be in the 5% or 10% duty cycle range at 100 amps. Depending if its a EU duty cycle which I think is 5 minutes instead of 10 you may get 30 seconds of weld time before you exceed the duty cycle. Save your bucks and pick up a Miller, Lincoln, ESAB or Hobart. With no more power than it's got you likely wont be able to use anything but CO2.

Flux core is just an option. It should not have any issue with gas.

The ability of a machine to use a shield gas depends on having a solonoid to control gas flow and the necessary tubing to the welding torch or spool gun. there are some mig machines that do not have the necessary parts to use a shield gas. All mig machines are capable of using fluxcore wire. I didn't google that particular machine to see what it is capable of , but that would be a good idea before hard money is spent, to make sure it will do what you expect it to do.
