Welding procedure & parameters
DCEN (electrode negative — tungsten positive). Shielding gas: 100% Argon. Back purge with Ar for root passes on pipe. Wire dia: 1.6, 2.0, 2.4, 3.2mm. Current: 50–180A depending on dia and position.
Typical applications
Dissimilar GTAW, overlay on difficult steels, buffer layers before hard facing.
Storage & handling notes
Do not touch wire surface with bare hands — contamination causes porosity. Store sealed in original packaging. Pure Argon only — no CO₂ or He unless specified.
