Welding Amperage
Range
3-400*
*Welding range for Stick process is 5-400 amperes. For TIG, the amperage range is tungsten diameter dependent (see Section 6-3).
** Arc starting device is designed for manual guided operations.
*** Low open-circuit voltage while in TIG Lift Arct, or while in Stick with low open-circuit voltage selected.
♦ Normal open-circuit voltage (75) is present while in Stick with normal open_circuit voltage selected.
