2T, 4T

Welding guns can have several alternative trigger operation modes (trigger logics). Most common are 2T and 4T. In 2T mode you hold the trigger down while welding. In 4T mode you press and release the trigger to start or to stop welding. For more information, refer to “Trigger logic functions” on page 56.

Pre gas

0.0 … 9.9 s, Auto, step 0.1 0.0 = OFF

Welding function that starts the shielding gas flow before the arc ignites. This ensures that the metal does not come into contact with air at the start of the weld. Time value is preset by the user. Used for all metals, but especially for stainless steel, aluminum and titanium.

Creep start

10…90 %, Auto, step 1

The Creep start function defines the wire feed speed before the welding arc ignites, that is, before the filler wire comes in contact with the workpiece. When the arc ignites, the wire feed speed is automatically switched to the normal user-set speed. The Creep start function is always on.

Touch Sense Ignition

AUTO/ON/OFF

Touch Sense Ignition (TSI) delivers minimum spatter and stabilizes the arc immediately after ignition.

Wire feed speed

0.50 … 25 m/min, step 0.05 or 0.1 Default = 5.00 m/min

Wire feed speed adjustment. When the wire feed speed is less than 5 m/min, the adjustment step is 0.05 and when the wire feed speed is 5 m/min or more, the adjustment step is 0.1.

Wire feed speed min

Min/Max = 0.5 … 25 m/min, step 0.1 Default = 0.5 m/min

(Not available with MAX Cool and MAX Speed.)
When welding with high power, a crater is usually formed at the end of the weld. The Crater fill function decreases the welding power / wire feed speed at the end of the welding job so that the crater can be filled using a lower power level. With MIG process, Crater fill duration, wire feed speed and voltage are preset by the user.
When the wire feed speed is less than 5 m/min, the adjustment step is 0.05 and when the wire feed speed is 5 m/min or more, the adjustment step is 0.1.
For 1-MIG process, refer to the 1-MIG parameter table.
Post current setting affects the wire length at the weld end, for example to prevent the wire from stopping too close to the weld pool. This also enables the optimum wire length for the start of the next weld.
Wire feed end step feature prevents the filler wire from sticking to the contact tip when the welding ends.
Welding function that continues the shielding gas flow after the arc has extinguished. This ensures that the hot weld does not come into contact with air after the arc is extinguished, protecting the weld and also the electrode. Used for all metals. Especially stainless steel and titanium require longer post gas times.

3.4.5 WiseSteel feature
The WiseSteel welding feature is based on modifying the conventional MIG/MAG arcs to enable higher quality of welds. WiseSteel improves the arc control, reduces spatter and helps create an optimally-formed weld pool.
To take WiseSteel into use, go to the control panel’s Welding parameters view and apply the WiseSteel feature. >> To adjust the welding power/wire feed speed while welding, in the control panel’s Home view, turn the left con-
trol knob. >> To fine-tune the heat output while welding, in the control panel’s Home view, turn the right control knob. When using WiseSteel, different adjustment methods are applied at different power ranges (different arcs). The wire feed speed / current indicator shows the arc range: Short arc — Globular arc — Spray arc. Short arc range: · WiseSteel is based on adaptive short arc control; that is, the process adjusts the short circuit ratio. This creates an easily-adjustable arc and less spatter. Within the short arc range, the shape of the current is similar to the traditional short arc welding. When a short arc is used in vertical up welding where weaving motion is applied, WiseSteel ensures good quality through adapting to the changes in the stick- out length. Globular arc range: · Globular arc means that WiseSteel fluctuates the power between short arc and spray arc at a low frequency, so that the average power stays within the globular arc range. This results in less spatter than conventional globular arc welding, and a welding pool that enables excellent structural durability. Spray arc range: · Within the spray arc range, WiseSteel is based on adaptive arc length control, which keeps the arc optimally short. WiseSteel also utilizes micro-pulsed welding current. This creates a well-formed weld pool that enables excellent bead geometry and optimal penetration with smooth and durable joints, and speeds up the work. The pulsing is not noticeable to the welder. The shape and control of the current are close to the conventional spray arc welding. For more information on Wise products, visit www.kemppi.com.
