Hello, like many beginners I have been reading this forum for a while, and I must say it is great. I have recently bought my first welder, an old Sealey 150/1 for £122. I have replaced the liner, earth clamp, tip and nozzle to try and give myself a good start. It came with a pub bottle which when it runs out I am planning to replace with a CO2 argon mix. Here is one of my attempts to join two bits of box section. I would like to hear your comments on how I am doing and what I need to do to improve.
