We have had 5 weeks of our welding course so far and have focused on MIG only. It has been a steep learning curve but we are now able to produce reasonable looking joints. Coping with so many variables takes some getting your head round.
Talking to the other guys on the course they all commented that for what I am doing I might find TIG more appropriate. The tutor on our course suggested that TIG was like using one hand to pat your head while the other hand was rubbing your stomach and you were jumping up and down all at the same time. I can now see what he means.
After many hours of YouTube watching I have invested in a Jasic TIG welder that does both DC and AC so I should be able to do aluminium joints. It is a nice piece of kit and I am slowly learning its functionality.
So it’s back to practice and more practice but I quite like TIG. It is gentle and focused without all the sparks you get with MIG. It reminds me of my school days when I was doing gas welding.
No projects as yet but it is only a matter of time.
Despite being laid low with flu since New Year I’ve attended two of the evening welding classes much to the contrary advice from my wife. With hindsight she was right – I should not have gone the first night such was my state of health.
The focus so far has been on MIG welding and I am slowly getting the feel of things. Too many variables to start with what with power, angle of attack, closeness to the job and of course wire feed rate.
How anyone did welding without the modern auto dimming helmets astonishes me. They are amazing.
Not much else to report given the state of health but clearly I have now started to creep back into the workshop so health and state of mind must be improving. Made a note in the diary to get a Flu Jab next year.
Anyway more interesting stuff – my friend has asked if I can mill a prototype printed circuit board on the Tormach for him. My initial thoughts were to bring the design into Fusion and do the CAM there. However a conversation with a friend in Namibia lead me to FlatCAM which is a wonderful little program. It takes the Gerber files from the PCB design package and converts them to GCode. It is simple to use and produces nice code listings. It gives you options to add your own GCode initialisation strings. There are a few YouTube videos out there if you are interested.
More results to report when we have milled some copper.
