Mk2 TIG torch holder tested the other day. Quite a bit bigger compared to the mk1.
Works great, I'm really happy with the way the torch is held under its own weight. I have a video of retention and kicking the cable about and it doesn't let go.
I'm going to make some cosmetic changes to the...
Have you had the liner in and out?
Have you checked that the liner goes all the way to the contact tip? If it doesn't, then that can cause big problems with feeding.
There's a happy medium to be had. Stopping it with your finger is way too light a tension. I was taught it should stop if you headbutt the gun onto a table.
I agree, some of these small migs need the wire tension wound well in to run properly, I think sometimes it's a bad or worn roller profile...
I would scrap the wire and scrap the liner, and clean the feed rolls etc before fitting a new liner and wire reel.
Even if it does feed, that oil contamination will cause horrible porous welds.
As an employer, i don't care particularly that you haven't had employment before 23, but I do want to know what you have been doing since you left school. What life skills have you learned in that time? If you look hard at yourself critically you'll find you've learned something or other that is...
If you're going to order a volume, say 50+, then commercial laser etch and cut from a single sheet would be a good option... it might need enamelled afterwards though, commercial laser etch is quite light.
Or as Julian says, pre cut blanks, and desktop laser engraver, that would look awesome...
One of the scariest things I've ever seen was a level control system go wrong on a solvent distillation column inside a building, it spilled out of the reflux header tank which wasn't sealed, and filled the building with a dense cloud in less than 30 seconds.
3 of us were working in there. We...
Actually refreshed my mind on wiki and it was a bypass pipe for a failed reactor vessel. The flow was under gravity but the pressure was around 9 bar, in a 500mm pipe that's a lot of stored energy in a relevant fluid.
At uni we studied this, i don't remember anything about zinc embrittlement. The 2 things that stood out as causal were a replacement of a failed high pressure pipe using light sheet metal ducting type fabrications; and the zed shape of the replacement pipe coupled with the huge flowrate caused a...
You can't comply with that WPS if you don't have current readouts on your machines. Simple. You trim your wirespeed and stickout until you're achieving the required current range.
Wfs is maybe an allowable parameter on some wps but not on most I've seen, as its really the amps that matter.
You...
I'm surprised, it still should have been ok?
Been playing with mma tonight seeing how hard a 6G test is on 2"...turns out it's pretty hard if you don't weld for a living :D
Got a handle for the micortig set. It annoys me very much when they don't have a handle, or just that carry strap. £30 delivered feels like good value to me for a nicely engineered OE handle.
