Hi, After struggling with a MIG problem, It looks like the root of the problem is the gas.. I'm using C2 for SS welding.. 0.030 , 316L. When I push the trigger, the wire slowly burn and drop, with a lot of soot.. After trying many different setting, with no luck at all, I took my autoweld bottle, ho...

Cost.. 409SS is much cheaper than 304SS

Thanks guys for the advises, I'll go with 309L , I already have a few pounds.

cheers,
Marc

For some clarification, I'm doing custom downpipe in 409SS but all the flex used are in 304SS as well as
the vband, so that's explain the 2 differents material.

thanks,
Marc

Hi,

I wondering what would be the best filler rod to joint T304SS tubing with T409SS. Tubing are used in
exhaust system, so a lot of heat are involved.

thanks,
Marc

I have a 200DX and it's working perfectly after more than a year.. I'm really happy with it except that
i need more amps !

Thanks for the tip Len, I'm gonna give it a try with the wet rag and see if everything stay together

Thanks guys for the inputs.. Actually it's a generic photo i took from Google.. I'll perform this modification on a rear car shock that looks almost the same. I will machine a small tube to get the rod 2" longer, to allow the shock to operate in the optimal condition while the bracket on the ca...

Hi, I want to know if anyone has experience at welding on gas shock absorber. I need to cut and weld a new part ( located in the red circle, on the picture ). Is there any danger ? If I put the ground clamp close to where i will weld.. I just want to keep my garage in the same zipcode ;) thanks, Marc

thanks guys for the answers, It was actually only a test and wanted to see the process..

Akweldshop : keep posting the pictures of your MIG work, it's very instructive !

Motox,

I agree with you, but I don't understand this kind of answer.. I try to be clear, with all the details I can, to avoid confusion and get the most 'directed' answer..

why not answering the questions ? If I had wanted to MIG it, I would have done it.

Well, After reading a bunch of bad things about TIG welding aluminized exhaust pipe, I decided to give it a try. Bare with me about the welding, I'm at the wheel since a few weeks only.. From what I see, it turned out ok.. Just a quick scotch bright and no filler, just fused the pipe.. I used 1/16 T...

Finally got around the last problems, now I'm laying beads !

Here's the Saturday afternoon practice..

Thanks !, yes it's getting better.. I tried to practice each day at least one hour.. I have time to time a problem that I can't pin point.. On a lap join, as example, I get a "C" shape puddle.. As Jody say, I check the 3 things, and it keep coming back.. I try to tight the arc as much as I...

A little update, no pictures yet.. I've been able to mostly fix the arc wandering by hitting the pedal to get high amperage at start up and mostly form the puddle withing 3ish second, so that's an improvement.. but, the cleaning band is still large.. I tried to tight the arc as much as i can, but st...

Sorry guys, I totally missed those info.. Metal thickness : 1/8" Filler rod : 4340 1/8" Amps : 160A, with pedal control Cleaning is at 35% EP Machine : Everlast 200DX As the running amperage, I cannot see the display as I'm welding, but I'm not running full throttle> Im gonna try tomorrow ...

Hi, I give a first try to aluminum today.. Clean with an SS brush and acetone. I'm using 3/32 2% lanth that I balled. Balance is at 35% I have an Everlast that work backwards.( so 65% ), 120hz. And when I hit the pedal, the arc is unstable and moving around the tip until the puddle is created. After...

Looks like it also now works for me too

thanks guys for the comments.. It was a nice build.. 8-) motox : Actually, I looked at some pictures on an other welding forum from a guy that built a cart.. I adapted it to me needs. I just drew a basic sketch and start from there.. This summer, I'm gonna paint it.. It's winter here north of the bo...

Hi,

Here's my new welding cart.. I took the base idea on an other forum, and adapt it to my needs.. The free
space at the bottom will be for the tig cooler.. Only the wheels and the drawer slides has been bought..

cheers,
Marc

Thanks Oscar for the tips. I'm still trying to synchronize both hand for a good tempo, but looks like it something to get with practice ! ;) Here's an other try, same setup, inside and outside corner joint.. I'm still having problem with undercut.. Am I running too hot ? beads are less defined on th...

Hi,

After a few hours playing with my new TIG, I tried a lap join. Here's the condition. Plate are 1/8". Cup #6, 3/32 2% Lanth, filler rod is 1/16" E70S-2, 140 amps with foot pedal control and 17 cfh for Argon.

I would like some input..

TIG is an Everlast 200DX.

thanks,
Marc
