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 the foot pedal and the torch are just bad and clunky.
Primeweld went to extra expense to include genuine ck torches with superflex hoses along with a smooth SSC style foot pedal.
They also have a responsive primeweld equipment users group on facebook and also have demonstrated great customer support
Watch some primeweld videos and you will see what I mean.
WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING
METAL TYPE = TITANIUM 6AL4V
THICKNESS = .040”
WELD TYPE = GROOVE WELD
JOINT TYPE = BUTT
POSITION = 1G FLAT
AMPERAGE = MACHINE SET TO 100 AMPS USING PULSE SETTINGS AND FOOT PEDAL
TUNGSTEN = 2% LANTHANATED, 3/32"
FILLER WIRE = .045” CP TI

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.
