What Makes XP8 Different?
80% Duty Cycle
In recent years guidelines laid down by theEuropean Standard EN60974-7 have served to harmonise global understanding of MIG weldingtorch performance.The ratings of European torches were traditionally based on a 5-minute cycle where a 60% duty cycle was deﬁned as 3 minutes weld time and 2 minutes downtime. American torches were traditionally rated over a 10-minute cycle where a 60% dutycycle represents 6 minutes weld time and 4 minutes downtime. The new standards have resulted in the duty cycles of many European torch brands being downgraded in performance due to the extended welding period.
Competitive pressures have also resulted in MIG torches becoming disposable items and while the user may save on initial cost, the lossof performance and durability is ultimately false economy.
Duty cycles quoted by some manufacturers are at best misleading and often ﬁctitious. In line with EN60974-7 a duty cycle of a torch speciﬁes the number of minutes within a 10-minute period during which a welder can operate at a particular welding current and voltage.
The XP8 air cooled torch models are rated at 80% and will weld continuously for 8 minutes
at their given ratings. The XP8 water-cooled torches are rated at 100% duty cycle and will weld continuously.
