Tig welding 101

a dc power source such as a dc stick welder can be used for scratch start tig with a gas cooled torch like a 17v,or i like the smaller 9v.this is the "econo" way to go.if you want the top of the line the miller dynasty is as good as it gets.if your looking for an older used machine the linde welders are decent.if you want something new that wont break the bank,i really like the thermal arc brand.
