6 Soft Start Switch
The Soft Start feature provides a smooth

established, the wire speed increases to the
weld wire speed.
When using small diameters wire, or with in-
verter power sources, it may be necessary to
turn switch off to obtain smooth starts.
After adjusting the switches, close and latch
the door before welding.
