POST FLOW = 10 SEC
TIPS: KEEP A FAIRLY TIGHT ARC AND WATCH TORCH ANGLE
Aim for an arc length that is equal or less than the diameter of your tungsten electrode. Torch angle can be forgiving provided your arc length is tight.
In my opinion, the primeweld 225 is one of the best choices in affordable tig welders.
The problem with most other really affordable tig welders is usually a really cheap foot pedal and TIG torch. Primeweld went to extra expense to include a genuine CK17 torch with superflex hose along with a very smooth SSC style foot pedal.
A high quality CK dinse adapter is also included so that you can easily swap out a tig torch or cable when the time comes.
Primeweld also has a responsive primeweld equipment users group on facebook and also has demonstrated great customer support
