NOTES

Note
⁽¹⁾ CTWD (Contact Tip to Work Distance). Subtract 1/4 in (6.4 mm) to calculate Electrical Stickout.
⁽²⁾ Procedures in these areas are procedures for short circuiting mode using 75% Argon, 25% CO2. NOTE: For 100% CO2 procedures, add 1 to 2 volts for short circuit transfer and 2 to 3 volts for globular transfer.
