*Do not change Voltage switch position while welding. Wire Speed value in Table is a starting value only, and Wire Speed control setting can be fine tuned during welding.

** When welding aluminum, for best results, use .023–.035 v-knurled drive roll and a contact tip one size larger than wire diameter... Ref. S-187 939
