Filler rod

Bandit30019 · Tue Jul 19, 2016 8:54 am

I have a 200amp tig ac/dc does great on aluminum wets nice but on the DC for steel it forms a puddle good but when I add filler it's harder to add it doesn't seem to mater the size 1/16-1/8.I've been using the e3 3/32 seems as though the tip stays at the front of the puddle no matter the position of the Tourch.

What do you mean "it's harder to add", exactly?? what "tip"?

I would imagine he means that the rod is burning back before he physically gets it into the front edge of the pedal.

That would be a bad torch angle or too long of an arc. Its easier to watch Jodys videos on torch angle than it is to explain it so that would be a starting point for you. You are melting off the tip of your filler because you have too long of an arc length or bad torch angle which is aiming the arc at the filler rather than the base metal so its melting off before you can dip.

I keep the touch angle straight up and about a 1/4 stick out.no problems on aluminum. Mabe I'm tilting not knowing it .I haven't tig welded in a while little rusty.thanks

Stickout and arc length are completely different things. If you are maintaining a good torch angle and still melting your filler off, then you have too long of an arc length OR a radically wrong torch angle that is pointing toward your filler rod and melting it off before you can dip. If you can send in some pics, there are plenty of good welders around here who can "read your bead" and tell you exactly what your doing wrong. There is nothing new under the sun as far as welding goes so if you can submit some pics, you will find out what you're doing wrong
