spluttering weld

hi all got a rtech 180 mig and its cool but im struggling to get a decent weld, it sounds very stuttery and popping , ive tried the settings doubleboost used in his review videos but no joy , have been trying different settings also but no luck, the weld look ok but the stuttering is very off putting, any advice.
im using hobbyweld 5 gas.

 

Is the work piece clean, make sure you're not welding in a draft. Has the tension been set on the feed rollers correctly. Try increasing the wire speed. The wire should be in the puddle constantly. Just my suggestions about the obvious you probably have tried.

 

hi work piece is clean, was welding outside but no drafts as far as i could feel, but maybye, tension on feed rollers could be looked at im not sure if thats right, and wire speed , i will try and check that also, thanks , its just frustrating when you watch john use it out the box and welds are great, i use same settings and its all over the place, practice practice practice i think.
thanks for your reply and help

 

If it's stuttering it sounds like you might need to turn the wire speed down or the power up.

 

If you have a friend that could adjust the wire speed as you weld
Or adjust it by a small amount each time
only adjust one thing at a time
make sure the earth is good
To fast a wire speed can cause this
To low and you will melt the tip
can you post a picture of the weld for us to see

 

if in doubt , put all the settings in the middle , and start from there ,,

pics will help us sus out whats going on better though.

 

thanks guys i will go out to garage and get some pics, the tip seems to be forming a small ball at end of each weld.
i have a small welding bench and good earth direct onto practice piece, welds dont look too bad its just the stuttering and cant see whats happening too well.

 

this was my efforts today

 

hi sorry it was on 4mm steel plate, it was clean when i started

 

more power / less wire
what gas are you using

 

hi john, thanks i will look at that, im using hobbyweld 5 gas

 

The welds look to be "sitting on top" of the plate
Can we see the other side of the welds

 

i will get more pics up, cheers

 

pics of rear of weld, there is some paint on backside which doesnt help image

 

hard to tell with the paint but looks not to bad

 

thanks I will try your suggestions tomorrow, more power less wire, you make it look easy mate, I will keep at it , thanks again

 

Double check you have the correct drive roller in for your wire size and that you are using the correct groove.

 

hi thanks aff, i had made this mistake already, changed it round thanks

 

5.5 and 7 on dials for 4mm plate according r-tech.
