Is there an easy way to determine which liner is installed in my Lincoln Weld-Pak 100?

That will work.

Approximately the same as the .030 liner coiled up in the Lincoln plastic bag...

The metal liner is for mild & stainless, The one that looks like a plastic tube is teflon an suiteable for alum.

I have some 1" round solid C45E H6 steel stock originally intended as 'shaft steel'.

Can I (TIG-)weld 4mm (5/32") thick 'normal' steel tabs on this rod? The C45/1045 steel contains more carbon than normal steel.

Regular ER70S2 filler rod OK? Preheat? If yes, how much?

I haven't yet welded such 'thin' metal to such a 'massive' block of steel before. Any tips?
(besides directing most of the heat to the massive block)

The ER70S2 will work. As for pre-heat 350 f should be enough. Depending on placement and number of tabs the shaft may wind up looking like a banana, you can either use heat or a hydraulic press to straightn the shaft after it has cooled.

OK, thanks.
I intend to make a few spacers out of it, so warping is not really an issue.

Question 1)

When MIGing a stainless exhaust tip to a stainless muffler, do I need stainless filler wire, or is ER70S6 (I think I got that number right) acceptable? Any drawbacks to this if it is acceptable?

Question 2)

Miller recommends an Argon / CO2 mix on my particular MIG for mild steel. If I temporarily used pure Argon until I get my C25 tank filled, would there be any negative results?

Thanks in advance.

Q-1. yes you need a stsinless fill wire. ER70S6 is a mild steel wire and SS cannot be welded with mild steel. However M/S can be welded with S/S (works but not recommended)...... Q-2 The recomended shield gas for MIG with S/S is either Tri-Mix (#1) or 75/25. Pure agon will work but it is kinda spendy to be using with a wire mach. CO2 will not work with S/S. When welding M/S to stainless use ER309L and Tri-mix, with wire mach or pure Argon with a TIG set up.

Just wanted to show off some recent work. Here is an intercooler I'm building for a bike. My aluminum welding has come a long way, but there is still a lot to be desired. My biggest problem is tacking up the work. No matter how much I clean the piece, I find it very difficult to get the filler rod to join the weld pool the first time I dip it. I've also tried pre-heating the work, but that doesn't seem to help either. Any suggestions?

fxstbiluigi · 11-04-2010, 09:09 AM

Clean the fill wire.
