22 Operation EN

RS 350 – 450 – 550 M / MW PRO

Pre Gas Setting Mode (PrE) When starting the welding process, the arc is formed before the gas flowing from inside the torch reaches the welding area. This causes the welding to start without gas. The start occurs in a spattered and deformed manner, with the pre gas duration, the gas is activated before the arc starts with the set time and the gas reaches the welding area at the time the arc is formed. By this means, clean welding takes place without any spatters. Setting range: 0.1 – 10 sec.
Final Gas Setting Mode (POS) After the welding is finished, the welding pool will remain melted for a while. With the final gas duration, the gas flow continues in the set time after the welding has been terminated and gas protection is maintained until hardening occurs. By this means, deterioration of material structure is prevented. Setting range: 0.1 – 10 sec.
Burn Back (brn) When the welding is terminated, clumping occurs at the end tip of the welding wire. By means of the burn back function, the burning length of the welding wire is adjusted and the clumping is reduced. This prevents the wire from sticking to the contact nozzle or from sticking the wire to the material. Setting range: 0.01- 0.5 sec.

on-time period and stands by during the length of off-time; the process continues as

long as the button is pressed. Welding will also be terminated when the trigger is

released.

If pnt is selected in the Trigger mode, the On and Off times as well as the welding and

standby times are determined.

On time (Ont) In pnt mode, the time the welding is active will be set. During this time, the welding will continue and the welding will stop at the end of the period.
Setting range: 0 – 10 sec.

Off Time (OFt) Stand-by time during welding is adjusted in pnt mode. During the set time, the welding will stop and restart at the end of the period. Setting range: 0 – 10 sec.

Soft Start (SoS) When the source is first started, the wire speed rises slowly from the lowest speed until reaching the set speed. By this means, backlash and spatters are prevented at the beginning of the welding process. Setting range: On – Off
Standby Mode (SLC) When the machine is not used after the time set for sleep mode, it goes into standby mode. This prevents unnecessary energy consumption. Setting range: On – Off
Cooling Time (Cot) After the use of machine has been completed, the water- cooling unit continues to operate for the set period of time. This prevents hot water from damaging the torch. Setting range: 4 – 10 min.
