Basic tig query

Just started to learn to tig weld mild steel yesterday. I’m just running little practice lines to get a feel for the coordination. I’m using 2.4mm tungsten at 30-35 amps for 1mm sheet metal and .8mm mig wire for filler rod.

My question is: my weld / weld pool seems really skinny / small (coming from mig welding) - like 2mm-3mm....is this normal for what I’m using? Or am I not using enough filler rod

I haven’t butt welded anything yet so I’m not sure on how much penetration I’m getting with the welds.

appreciate any help

You probably need to either slow your travel speed or more likely increase your amps which will create a more fluid weldpool, the problem you will then have is you will probably start to get porosity as you are using MIG filler wire

Mig wire works for tig, .8 wire is going to be a pain though. Get some 1.2mm tig wire it's already straight and it will give you a better bead.

For mild steel?

For mild steel?

ER70s-6 mig wire is triple deoxidised just like tig wire.

Sorry, my mistake didn’t realise the OP was using ER70s wire
