Sip migmate turbo 130 - Blowing holes.

[Stevo1600]

Hello everyone, ive been reading these forums for a while now and thought id best sign up to ask a few questions i have.

Firstly im very new to mig welding, with probably less than 24 hours worth of experience.

Anyway, my welder is an old sip migmate turbo 130, yes i know its pretty old but i wanted to try out if i could actual weld and it was cheap.

Now, i have got a problem which i cant seem to figure out, when i try to weld exhaust pipe, or car body panels, the welder just blows holes right through it, even moving silly fast with the gun and on the lowest settings i can get it to.

Its set to the lowest settings with 0.6mm wire.

Can wire speed have an effect on how "powerful" the welder is? i ask this because the wire speed nob doesn't work very good, and it really does push the wire out rather fast. Can wire speed set to low cause problems also?

Also if any one has experience with one of these welders, any tips to turning the power down so i can at least weld exhaust pipes etc would be awesome.

if its down to the welder being to old, well, i can always practice on some thicker stuff, and buy a modern unit in the future.

Thanks.

wire speed will effect the quality of the weld.

I have a different welder and this is me trying to weld 0.8mm steel with 0.6mm wire on my lowest power setting

and as you can see its not so good and blowing holes

this is using the same settings but pulsing the trigger with overlapping tacks to limit the heat input

you seem to have worked out how to do it, on thin steel you will find it hard to continually weld a butt joint
unfortunately the sip welders are a bit cranky when it comes to wire feed and there are a few threads on here for modifying them, you could try some switch cleaner on the variable resistor that controls the wire speed, regarding actual wire speed, too fast with little power and you will have cold tall welds too little wire speed and it will burn back to the tip, have a play with it and find the best settings

thanks guys, im going to give the pusling trigger technique a go, that welding looks very good on the second picture. on the first picture, thats the same results i get everytime i weld thin steel.

I have modified the welder, i replaced the wire feed tupe/pipe with a steel one, which is what everyone recommended. Ill just keep practicing and see how i get on!
