Been messing with Mig for some time now, nothing mega just garden ironwork etc.
Always looking for self improvement and bettering my weld knowledge I thought i'd post up a picture of a recent project and see how others would handle it.
This is a large fire-pit, 6mm plate, about 100kg all-in.
So, at A & B we have a stretcher plate, there is one between each leg, these were tacked all round then I did a full length fillet top-downwith the gun pointing upwards so effectively a downwards drag.
At C, D & E i used a 50mm stitch again top-down but pushing this time so torch point downwards.
All joints made at 23v probably 140-150A, 0.8mm wire on Argoshield light gas.
All went well apart from E, each time i got about half-way through this stitch, the arc changed to what appeared to be severe low wire feed rate, sort of turned into a flame instead of the usual effect. Not sure why, if it was a kink in my feed cable i doubt it would have done it every joint the same. Likewise if the feed had been slipping - not every joint would be the same.
Any suggestions overall or specific to joint E most welcome, I'm going to do some tests this weekend to try and see exactly what was going on in there, also want to try upping my wire feed rate as i just never seem to get a good sizzle going on, always crackly/poppy instead.
