Re: Welding Wannabe
HERE is probably your best bet. How is availability in Oz? I think you're doing all of the right things. The course is a winner and the selection of TIG for what you describe sounds like a winner too. My only advice would be to have patience. TIG is heavy on monkey skills and won't come automatical...

Re: Pulsed MIG Shielding Gases
At the risk of sounding critical, which I don't want to do because I'm sure I don't have a fraction of the welding experience Ed has, he does have some negative issues. A lot of the projects he touts on his website or in his books are companies that he has failed to convert to his platform. I still ...

Re: Tig welding - pin holes
Bubbles and porosity are normally caused by dissolved gasses which come out of solution as the weld pool cools. Hydrogen is a notorious culprit. Dirty weld surfaces and water can contribute to that. I also noticed that it happens more with copper coated filler metal. I've had some old dogs tell me I...

Re: Cheap tungsten sharpener?
I've been eyeing a little bitty bench grinder at HF. The wheels are only about 3 inches and are very fine (just like I'd like for a tungsten). It was about $30 or so, so cheap enough to use as a dedicated tungsten grinder. Also cheap enough to modify with a tungsten holder that grips and twists and ...

Re: Spray Vert Down
Speaking of. . .the manual says pulse-on-pulse is exclusively for aluminum. Maybe a question for Scott, but has anybody tried it on mild steel or stainless steel? I'd be real curious if it had any value in that regime. I may give it a shot when I load stainless in my reel next. Since it is a compute...

Re: Prowave 300
tinmantech.com sells small tubs of flux for OFW for stainless and aluminum. Maybe if you tried his Al flux just as a troubleshooter. Point I was getting at though is to make sure you aren't getting the oxide skin. It can have a profound effect on the flow of electrons in the plasma. If your Ar is co...

Re: Prowave 300
Larry, Another thing to consider that contributes to blow is rectification, which is characteristic to aluminum because an oxidizing skin builds up on top of the weld puddle and resists electron flow from the puddle on the EP stroke. You may want to try using an aluminum flux (even though not called...

Re: Prowave 300
Based only on what Scott posted, my first guess (and certainly not an experienced one at that) is arc blow. Looking at all of the ways this can occur and what the solution is for them, has he looked into that? I realize that aluminum won't build up magnetic effects and cause it, but if he's using a ...

Re: Lincoln Customer Service Experiences?
I've made 2 or 3 tech assist calls to Lincoln and had pretty good luck. When I had problems with my PM300, both the Phoenix and San Diego district reps were very involved and provided 100% satisfaction. It was ultimately the local welder repair guy that got district reps involved and I otherwise wou...

Re: tig welding anodized aluminum
In the aircraft maintenance biz, whenever we do corrosion control touch-up work that gets the skin down to bare aluminum, we apply a chemical conversion coating (I think alodyne is one commercial name for it) which forms a thin anodized layer. Obviously you can't weld anodized effectively, and scrap...

Re: Pro-Wave® 185TSW AC/DC 185 - Aussies take note
It doesn't always spray (especially with DC power and electrodes) and it's really gratifying to get a good stick weld that approaches the quality look of other welds. A must for the 'all around' weldor.
