I need advice on welding very small metal balls to the tip of pen nibs. Long story there, but fountain pen nibs have tiny metal balls welded to the tips, then...
Is the welder TIG, i.e., use inert gas? Or a type of spot welder using no arc? What type of microscope are you using? Please be specific about the type of...
Char, I would tend to believe that the balls are induction welded to the nib. A gas or electric welder would not be controlleable at that small of a weld size...
Figured so! I have lots of experience with the torch but none with the pulse welders other than to look at them online. Hope this builds a long and strong...
I have used welders like the one in the last bottom pic in this: http://www.matrixsalesinc.net/unitek/ These are expensive. There are a lot of DIY info about...
I dabble a little making garden art out of scrap metal. I would like to be able to bend steel up to 1/4" thick and also 3/4" rebar. I have been reading online...
Propane torches work just fine, it just takes a little longer to get the metal to the same temperature. The propane is just not quite as hot as acetylene. Â ...
You really cannot weld with propane but most scrap yards use it for cutting w/ oxygen. I have both setups including propane rosebud for heating. It is ok but I...
... Actually, ambient air induction is sufficient for a forge which will get to welding heat. See http://ronreil.abana.org/design1.shtml#Reil for some...
This may seem too retro but what about charcoal and a blower. You could go modern and use an electric blower. From what you describe doing I think it would...
I have a low cost harbor freight TIG welder. I have been getting poor results with it, and I think it is because I can't see very well when the arc starts...I...
I've been asking around this question for awhile at work, and was wondering if anybody here knows the answer. Sorry in advance, I know I"ll probably get flamed...

jb - Sorry for my tardy reply. I bought an Orion 100c. It's a micro TIG welder, uses argon gas, and I can adjust the pulse from 3 to 100 Ws. The microscope is...
Hi to all of you, First thank you to be a member of your group. In relation of the mig stated above, I onwed this mig welder for 12-15 years and still working...
... If it is convection cooled, consider adding a fan and an air filter. The welder may heat up exactly as fast, but cool down should be faster IF all...
I don't know the particular unit, but I don't think there is anything you can do to increase the "duty cycle" itself. I would suggest making sure that it...

It is TIG - micro TIG. Pulse arc. I'm getting better, but the nib melts before the wire does. I continue to experiment with lower wattage, but it's hard to...
to be "thermally correct" about it, it will also heat up less during welding when under forced convection from a fan. The reason is that the components under...
"Duty Cycle" is (in my opinion) there for a reason - so you won't burn the unit up. Weld, then wait for it to cool down, then weld some more. If you can't...
Hi Ken, The cleanig is done twice a year to make sure area is Ok. Since it will be a light trailer, it is done with channle 2x1x.125 external frame and with...
Hi James, If I can not increase the capacity of my welder, I will buy something more capable than the one I have. Thank for the advice and have a great day ...
