Non-latched mode 

 

Figure 5-12 

Step 1 

•  Press and hold torch trigger. 

•  Shielding gas is expelled (gas pre-flows). 

•  Wire feed motor runs at “creep speed”. 

•  Arc ignites after

 

the wire electrode makes contact with the workpiece; welding current flows. 

•  Change over to pre-selected wire speed. 

 

Step 2 

•  Release torch trigger. 

•  WF motor stops. 

•  Arc is extinguished after the preselected wire burn-back time expires. 

•  Gas post-flow time elapses.
