Before I start, just thought Id say Ive done bits of Arc Welding in the past but MIG seems quite different to grasp.
Anyway, the equipment is - Cebora PocketTurbo 130, Co2 Gas (BOC X Sized Bottles), Brand New Wire Liner Fitted, Brand New 0.6mm Tip, New 5kg Reel of Mild Steel Wire.
Ive been playing round with welds on some 2/3mm plate, just laying some beads down. Had it on the second power setting, and the wire at about 50% speed. After a bit of patience and practice I got some beads that seemed to have good penetration, and looked very nice (Mainly thanks to the information on this site). The wire feeds very very smoothly after playing around with the tension, which seems to be good now.
After a few evenings of laying some runs down, and welding bits of plate to each other using the overlap method, the welds were still looking nice. Unfortunately got no pictures of this, but if needs be I can later this evening.
So today I decided to try welding a few bars together. The rollcage on my car was fully welded in last year by a friend, after I had profiled all the pipes etc, so the structure is all there and solid. Ive been rebuilding the car over the winter, and decided to add a few bars into the cage, mainly just for looks more than anything.
Ive had the new bars profiled for a while, and was just going to tack everything in place then take it to the same person to weld it in, but then thought to be honest my equipment should be easily capable of it, its just the user that needs to be too
Anyway, the cage structure is 45mm CDS, 2mm or so wall. The new bits im adding are 45mm CDS, 1.6mm wall, mainly to keep the weight down and as they are not structural. I tacked one of the bars into place where I wanted it, then decided to give welding a portion of it a go. At the end of the day if it didnt go well, Id just cut the bar back out and make a fresh one, as ive got plenty of CDS.
I set the welder to the lowest power setting (out of the four settings) and left the wire speed on about 50%. The thing was, the 'new' 1.6mm wall CDS seemed to just disappear/melt like there was too much power going through the metal. What would this be caused by, surely not too much power, just technique?
I went round 90degrees of the pipe using a 'weaving' effect, and this is how it came out...
Now being new to MIG welding, any comments would be welcomed as the main reason I have posted up is to get help with what im doing wrong, so ultimately I can learn how to weld better (and not to mention stop paying my mate to do all the welding for me).
Thanks if anyone has any tips/suggestions as to what im doing wrong
