GM**0S - Barrel

Good Mig Welding slid wires

Description : GM**0S is a kind of welding wire with low Carbon, high Mn & Si, negligible impurities of S, P.

Characterics on Usage:       

• GM**0S is a solid wire with godd arc stability at wide range of current especially low current ranges (short-circuiting arc range) and its spatter loss is low. 
• It's suitable for all-position welding steel sheets by CO2 or Ar+CO2 mixture gas shielding, for higher speeding welding.
• GM**0S is suitable for carbon steel, mild steel such as automobiles, vehicles, electric appliances, ships, bridges, steel frame, pressure basin, pipe, high pressure in all position.…

Usage introduction:

• Flow rate of shielding gas (CO2) should be *0l/min generally.
• Flow rate of shielding gas shoulde be ****0l/min under the condition of 2m/sec wind speed and use wind screen under the condition of over 2m/sec wind speed..
• In vertical downward welding, wire should be held at an angle slightly more than a horizontal.
• Keep the distance between tip and base-metal within ****0mm at less than **0A welding current and within ****5mm at over **0A.
• Optinum arc voltage should be selected in accordance with welding current to maintain stable tip transfer mode. If voltage is too high or too low, dip transfer frequency will decrease..
