Shielding Gases for GTAW (Gas Tungsten Arc Welding) Process
Argon provides good arc starting and stability as well as excellent puddle control and controlled penetration.
Part # AR *
HydroStar H-2 provides greater thermal input and a faster welding speed because of its hydrogen content,
making it a good choice for automation and when welding thick work pieces.
Part # AR STAR16*
HeliStar 25 – Because of its helium content, it provides greater thermal input and a faster welding speed
which has special applications in automations and in fabrication of austenitic stainless steel tanks and pipes.

Shielding Gases for Flux-cored Welding
Different percentages of CO2 with argon up to 100% CO2 can be used for flux-cored welding depending
on what the consumable is certified for. You should always consult the manufacturer’s product data sheet.
