By increasing the wire feed speed, the SA mode enters seamlessly into SSA mode, while preventing the globular mode. Thanks to its quick arc control and using appropriate programming, SPEEDTEC 320CP can artificially extend the Short Arc range to higher currents, in the range of the speed short arc. - Page 13 Reduced smoke emissions compared with customary methods and even-speed short-arc (up to 50% less); Pulsed SPEEDTEC 320CP programs for stainless steel eliminate the small spatter that may occur on thin sheets at very low wire feed speeds. These "balls" are caused by slight spraying of the metal at the time of droplet detachment.

Page 14: Advanced Welding Cycle
Advanced welding cycle Step cycle 2S Pressing the trigger activates wire feed and pre-gas and turns on the welding current.. Releasing the trigger causes the welding to stop. The Hot Start cycle is validated by the tHS OFF parameter in the general Cycle submenu of the . - Page 15 Spot cycle (…) Pressing the trigger activates wire feed and pre-gas and turns on the welding current. Releasing the trigger causes the welding to stop. Adjustment of the Hot Start, down-slope and sequencer settings is disabled. At the end of the spot time-delay, welding stops.
- Page 16 In Smooth mode (short arc), lowering the fine-tune setting enables achieving a more dynamic transfer mode and the possibility of welding while reducing the energy carried to the weld pool by shortening the arc length. A higher fine-tune setting causes an increase in arc length. A more dynamic arc facilitates welding in all positions, but has the disadvantage of causing more spatters.
