Linde’s Stargon™ VS shielding gas is a proprietary blend of argon, helium, and carbon dioxide, designed to meet the demands of your (GMAW) MIG welding carbon steel weld process with enhanced performance and lower operational costs. Stargon VS gas blend provides high arc energy, when welding carbon steel, which stabilizes the arc and allows maximum wire transfer rates and travel speeds, focused penetration and excellent bead appearance – good wetting, flat crown and minimal spatter.
Stargon VS shielding gas, as compared to common shielding gases C-25 and 90/10 shielding gases under the same conditions: 70S-6 .035 wire, 3/16 in. fillet weld. The results speak for themselves.
|Wire Feed Speed: 450||Wire Feed Speed: 600||Wire Feed Speed: 750|
|Voltage: 19.5||Voltage: 22||Voltage: 26.5|
|Deposition: 7.4 lbs/hr||Deposition: 9.8 lbs./hr||Deposition: 12.3 lbs/hr|
|Weld is somewhat erratic arc, large amount of splatter.||Decreased spatter and increased travel speed compared to C-25. ||Weld more controlled and consistent compared to C-25 and 90/10 and completed in the least amount of time of the three. |
When welding with a 15% duty cycle, Linde’s Stargon VS welding gas produced 15 parts per hour, a 20% increase in productivity over 90/10 and a 40% increase when compared to C-25.
