Hi, I'm completely new to Mig welding so just setting my self up as a new hobby in my dotage. Still waiting for the R Tech 180 which I ordered last week apparently because of the Suez crisis they are still waiting delivery. Anyhow, I bought my first bottle of gas this afternoon (5% CO2) from SGS he did the 20L for £60 plus deposit at £100 plus VAT, would this be a fair price?
