Hi Folks,
Gas supply aint working on my AC/DC 161 tig, checked all the obvious, gauges, bottles, lines, I'm guessing a gas valve, but any other possibilities?
Maybe I didn't explain my problem very well, the problem is during welding, not the dwell on the wire feed after welding.
It does seem like the wire is getting stuck on the contact tip during welding, could this be possible?
I use 1.2mm 1050 ali with a standard 3m Binzel torch, I'm using a Kemppi welder with a Synergic 1050 programme twin roller w/feed & I don't have a w/feed problem, but haven't tried a 4m torch, make sure you have the correct ali rollers specific for ali and the correct contact tip, which is 1.2A...
I'm using an inverta Cebora welder on 1mm mild steel with 0.6 & 0.8 mm wire, tried both sizes, the problem seems to be the wire sticking to the contact tip as it's spluttery and also creates a molten pool without wire feed, if anything the wire feed tension is on the high side so I know it's...
I'm a signmaker, I run my own business & I've felt the brunt of the decline of the high street personally, the only business' opening up are chicken shops, barbers, nail bars & phone dealers, mostly cheap price driven business owners running on a shoe string. Luckily I don't rely on that work...
I wouldn't use Lazze as the best instructor for metashaping, he's self taught, lurks around the metalshaping sites looking for ideas to claim as his, never seen him weld either! He over uses the shrinker/stretcher tools, shrinking is usually kept to edges where the weld join is, so the marks are...
In answer to the question, you would place this part over a dolly/stake of the shape you want, then with a flat faced hammer/slapper, hammer out the marks gently, trying not to stretch the metal.
The use of a body file would be necessary aswell to remove shrink marks, annealing not absolutley...
Another Gt, getting revived, jolly good:thumbup:
With regard to using thicker steel, the MG is mostly 0.9-1mm, which perfectly good, 1.2 is difficult to form & cut imo & will always be noticeable as a patch repair.
I'm doing a GT too, I like making things...
I think what you find why the bubbling returned is NOT PAINTING the EDGE & UNDERSIDE PROPERLY & only dealing with the face side, its so important to prep the eges to avoid reacurrance like this.
You could "tip" a flange over from the sides, maybe an inch, scribe a line then start to pull over with pliers, crush the ruffles into each other, your lid should fit then
1k etch primer doesn't need thinning, however if you are having trouble getting it out of the gun, use some 2k thinner.
It's a bit overkill to prime & paint a fly press, but it's up to you, 2k gloss is good enough.
Whenever I export cad files I always give dimensions in the file so scaling can be checked, as said above mm & inch Import/export scales are applied when saving files. The worst one I get are, cad files with line strokes applied to objects, nightmare trying redraw them.
Looks like heat expamsion to me, forcing the joint apart, was the panel bonded together or was it welded & seam sealed over?
Could do with a bigger photo of the surrounding area.
