Looks like lack of gas or VERY dirty metal. Oh and one thing I consider necessary is a gas lens, my welds went 10x better after getting one.

sorry if this has been answered already, this thread is getting long...

can you mig weld on a steel bicycle frame? I've seen some high end tig, but that's outta my league.

thanks

I was looking into this welder as well, with the thoughts of being able to weld aluminum.

Interested in the collective's thoughts on this model too.

Or another comparable model.

Is the torch water cooled?
What is the duyt cycle of the machine? what is the max. amperage of the machine & torch?
and finaly what thickness of alum do you intend to weld?

David R · 05-13-2011, 08:08 PM

A miller 211 is a mig welder. You CAN weld aluminum with a mig welder, but its a bitch unless you have spool gun or a TON of patients to try and get it to go through the machine. They make a nylon liner they claim will work. All they ever did is piss me off. I use TIG or if needed a spool gun.

Its like trying to push a rope.

Don't bother with the auto set feature, learn to use the machine and settings. Almost all have them inside the cover.

Here it is.

I have this one, but the older model that will not take a spool gun. Its an awesome welder, I keep .030 ER70S-6 in it with C/25 or Co2.

bergermeister · 05-13-2011, 09:12 PM

so, as far as mig welders go, you like it?

Ironrdr · 05-13-2011, 11:38 PM

I would purchase a spool gun with the 211. I'm not even gonna try to push aluminum wire through the regular set-up.

I currently have the Millermatic 130. I want to step up, but I don't know if the 211 is big enough of a step.

I can TIG weld better than I MIG, but the MIG is just so much easier and quicker.

Thickness of aluminum to be welded will probably be from .080 to .125.

I love it. I have quite a few RED welders this is the only blue one. A lot of the time its turned all the way up. I have buned up almost 20 lbs wire since I bought it in December. The M10 gun is kind of cheesy and running the machine all the way up the gun cable can get warm. A bernard gun would be a good upgrade, but its not required. I have a OLD SP100 for the smaller stuff. I keep .023 wire in that one. At first I thought the passport would replace the old Lincoln, but only if I used .023 wire. This would limit the MAX output on the miller.

Do I need to get all the chrome off before hitting it with a mild steel wire feed??

Marc

no. The chrome will just melt into your weld.

Power MIG 140 or 180 or 216 plus

The least expensive Lincoln Spool gun for aluminum welding using a Lincoln Power Mig is the Magnum 100SG spool gun. It is about $200 (at most)

The Lincoln Power MIG 140C (110Volts)or Power MIG 180C (230Volts) or Power MIG 216 (230Volts) all use the magnum 100SG spoolgun.

I have used all of them with great sucess. The bigger the welder the thicker you can weld.

That is why you need to grind the chrome off for about an inch all around the weld area.
By not grinding, before you weld the joint, you are adding chrome to the metal and changing the composition and grade of the steel.
Probably won't make much difference in the application you are talking about,
But I wouldn't want someone welding on a frame, of mine, with that same disreguard for the intergity of the frame material.

thank you RD post 1995- one of my first stops was to the local welding suppy place. at that point i was starting to complie a very long, "what if" list. i asked and got a light weight fiberglass burn tarp/cloth. only 6 X6', but that was pleanty( along with lots of 4mmplywood (already on hand) to protect wooden stair treads and flooring. turns out that the fiberglass burn cloth was about the same price as the equivalent plywood!!! thanx again!!
