I have to tell you, I bought a "Hands free" helmet from Cherokee welding helmets (click here) years ago and love it. It works like this...

It has a large viewing area and is perfectly clear when you lift the lens instead of the number 4 tint of an auto dark. I have tried many auto darks and go back to my Cherokee every time.

Thanks for the input guy's I had already reversed the polarity before I started trying the new wire. I played with heat and speed setting some today and got better results, stll need a lot of practice and my friend Jim came over he played with it and no matter what heat or speed he seem to have perfect welds..It made me feel some better knowing it wasn't the welders fault. I bought it back in 98 but have not used it very little and then it was with flux wire.

Take Care

i checked it out and I like what I see, anyone know how much it costs approximately for roll

[risaacp]

I bought some about 1 month ago and it was $27.00 for a 10# roll.

You would be SOL if you chewed gum

I've tried the new 20 gauge wire. Having troubles. Must be something simple that I've overlooked. I have a Lincoln sp 175 plus--set the polarity as if I was using flux core wire (DC-)--mig settings volts E and feed 2.5. Getting burn through on a lap joint weld. Using a 3/8" stick out 25psi argon/co2 mix. I'm welding 20 ga. cold roll sheet metal. Getting a yellowish orange arc.

After reading a number of posts looks like reducing my heat setting --moving faster.

Looking for suggestions for wire feed speed----Is the polarity set correctly.--is gas psi correct. What are others members who are using using a lincoln setting their heat range for 20 ga. sheet metal .

Thanks in advance for any help or suggestions.

Reverse your polarity..20 gauge is the same setup as solid wire feed..flux core runs the opposite in polarity..

Check your settings according to the lincoln reccomendations..should be a reference sheet pasted inside the lid of the wire feeder..E setting and 2.5 might be a bit much..I would have to try it myself to see..

25 psi is a bit much..about 15-20 is all that you need..if the wind is blowing you will get blowout of the shielding so shield your work from the wind..if you are in a building that part should be ok..

Doing that stuff should get you in the ball park..

Good luck

That and make sure the metal is CLEAN!!!
Wire brush the joint area and make sure it's CLEAN.

Did I mention the metal HAS to be CLEAN???

Most welding failures are the result of contaminated metal. It's amazing how just a little rust,old paint,sealer,ect will SCREW your joint.

Dseaver, as mentioned earlier you have the wrong polarity and that will lead to burn through. Adjust the voltage and wire speed for the correct frying sound and adjust forward rate to control penetration.

You may find the recommended settings are quite far off from what works well. I found perhaps 25% error in both wire speed and voltage selection on the Miller 175 vs recommended settings which just wouldn't work. The table inside the welder and the table for the twenty gauge wire don't match up with what works well.

I went back to standard .03 solid wire and have equivelent results as I get with the twenty gauge. I find the twenty gauge makes a lot of noxious fumes and it makes the work harder to see. I really didn't notice any advantage and the fumes and smoke were nasty.

Old red , does it leave a slag coating like dual shield?
And if so how does it "tack" , i know sometimes the bigger stuff requires quite a bit of heat to get a good one.

I really like dual shield, you just can't wear a white shirt, and you can almost say goodbye to porosity for ever.

Ya inner shield is terrible unless you are outside and welding big stuff, then it is only as good as the convenience of not packing and moving bottles.

Now they just need to make it a little softer, so it is not harder than the parent metal.

[oldred]

No it does not leave a slag like the duel-shield however it is not quite as clean as solid wire, just a bit dusty, but nothing that does not easily brush off. The core of the Twenty gauge is a powdered alloy mix instead of a true flux and this alloy does contain some deoxidizers in the form of Silicon and Manganese but no mineral type flux that would form a slag.

Will be using some again this weekend after a 2 year layoff-

After reading the above posts I'm confused(not hard to do)

Is the polarity DC - or +

tx,

Keith

[oldred]

The polarity has to be set on DC+, electrode positive (Reverse polarity). You may be confused by a common error, it is sometimes thought that DC- is reverse polarity but it is the other way around and electrode positive is reverse with electrode negative being straight polarity. Electricity flows from negative to positive so when you have the electrode set for DC positive you will have the current flowing from the work to the electrode (reverse polarity). When the welder is set up for electrode DC negative the current flows from the electrode to the work (straight polarity).


Anyway just set the polarity to DC positive and you will be fine.

Thrusty Oldred,

Thanks

I looked for twenty-gauge wire and had virtually no luck.

Here's what they said:

Sorry for the delay. Harris still makes twenty gauge but only in 33# spools.
I don't currently have any in stock but could order and drop ship it to you.
If you would like more information or want to place an order please call
812-842-3600 and ask for Stephen Titzer we take VISA/Mastercard and American
Express. Thanks.

33# won't fit in my Mig-Welder at all !!
