Need help.......welding spare wheel well into boot......where do I clamp the earth clamp to?

Anywhere that has conductivity to where you are welding. Preferably something big and beefy, preferably somewhere close to where you are welding. What about the supports at the sides of the boot? That's where I had mine clamped.

I would avoid gasless mig if at all possible.

It's no worse than a stick welder...

But would you take to your car with a stick welder trying to weld a spare wheel well into the car?

 

Gasless is quite different to standard MIG (or GMAW as the now more technically correct term). The wire structure is different hence it creates a different type of arc and you get all kinds of funny stuff happening. I just don't think its very suitable for welding thin metals. The most delightful machine Ive ever used for welding thin metals was a 350amper. It was hugely powerful (welding 15mm plate was a breeze) but you could ajust it so delicately down low.

Well, no I wouldn't. Not on sheet metal anyway. I do know people who would, and do, though.

 

And yes I agree standard MIG rocks, a heap better than gasless (I've been using my "standard" one gasless for a bit because I don't have any gas at the moment). Flux core wire isn't all that bad, but it isn't as good as normal wire with gas either.

 

And yes, the MIGs at Tafe rocked. My little thing is so crap in comparison...

Yea...but youd expect them to be that good for the price...mmm remote hand controller.

 

Apparently flux core shortens the life of your gun lead sleeve because it leaves crap all inside it?

Hmm... Possible. But isn't the flux on the inside (hence flux core)? I didn't buy the flux core wire, it came with my welder...

Would have to agree with Irokin.

 

Get a real Mig and you will notice the difference.

 

Won't tell what our WIA 180 cost but I'm sure Irokin can guess.

 

Best carton of piss I ever bought. (oops)

gasless mig is good if you are in a really windy place.
