Characteristics on usage
SM-70 is a solid wire designed for used Ar+CO2 mixed gas.
Its property is similar to SM-70(N) but with superior bead appearance and lower spatter.
The electrolytically applied copper coating ensures optimum feedability and current transfer at the contact tip.
Notes on usage
1) Use with 100% CO2 or Argon+15%-25% CO2 gas.
2) The shielding gas flow should be approximately 15-25 L/min
3) Use wind screen in draughty conditions
4) Keep distance of tip and base metal 6-15mm for less than 250A, and 15-25mm for more than 250A of welding current.
