thanks all for your help, another question is where do you get your scrap metal for practice, do you buy it from a supplier or is there some where you can source it for free? that's the only bit of scrap i could find and its not ideal for practice
I would go to your local fabrication business and offer to buy some small pieces of their scrap metal to practice your mig welding. You may be lucky or they ask for a couple of quid.
Have you fitted a new contact tip, check that it's the correct size, check that your running the correct polarity, with solid wire you'll need the work to be negative
hi I changed the contact tip to 0.6, the machine came set up for 0.8 so changed round feed roller too, haven't looked at polarity will look today , thanks
So your spluttering could well have been down to the oversized tip. You'll have the earth in the - dinse then?
Might be worth trying to weld inside to eliminate any draughts, at least you can then knock that of your list of possibilities. That's always been my problem with MIG and TIG outside.
hi yes thats true but i dont really have the room outside is the only option, i will have to make do im not gonna be building a space shuttle or anything. not yet anyway thanks
That was the problem I had with my last welding job. I cut and welded the separate sections up in the garage but it was too big to complete there so the final welds had to be done outside I didn't think there was much of a breeze but the welds were chalk and cheese with quite a bit of porosity. Granted this was with a TIG. Good luck.
As above, 0.8 for 3 and 4mm, and you might want to consider gasless for outdoor work. Some don't like it but worth a try with a small roll.
Think it may be wise to get it going well on gas before throwing in another set of variables , personally id rather stick weld than use gasless wire
