Stargon™ VS for Mild Steel

High Welding Deposition Rates and Excellent Weld Quality for Carbon Steel MIG Welding

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 is optimal for:

  • Metal cored and solid core welding wires
  • All position welding of carbon steel
  • Jobs requiring changes in metal transfer modes and electrode types
  • High arc stability at both low and high amperage

  • Can be used with multiple forms of metal transfer when welding carbon steel

Welding characteristics and low oxidation for enhanced performance

  • Helium allows for exceptional heat transfer when welding
  • Excellent welding arc stability at both low and high amperage

Reliable GMAW welding arc stability over range of surface conditions

  • Minimal porosity on galvanized sheet material
  • Less spatter on surfaces with light oil/scale

Formulated for Higher Efficiency and Productivity When MIG Welding Carbon Steel

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.

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.
Shielding gases have natural limits on deposition. C-25 gas lacks enough energy in the arc to stabilize the weld at high deposition rates, leading to spatter and undercutting. Although 90/10 is able to match Stargon VS welding blend’s 12.3 lbs/hr deposition rate, the quality is diminished by spatter and crowning. If your project calls for a flat, clean weld at maximum wire feed and deposition rate, Stargon VS shielding gas is the optimal choice.

Increase Throughput, Activity, and Your Bottom Line

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.
