Duty Cycle is the percentage of each 10 minute period of operation during which the welder is under load. So for your welder (20% duty cycle @ 90 amps) you can weld for 2 minutes of every 10 @ 90 amp or below and less than that above the 90 amp mark. Typically if your welder stops welding and then starts again, after it has rested for a while, you've poped its duty cycle. I'm confused, either I'm reading your reply incorrectly or I've got the wrong end of the stick - but I'm sure I'm correct!.

I bought me a Hobart 140 yesterday and gave it a little work earlier and had some questions on the duty cycle. I'm new to welding so I don't fully understand the duty cycles. How do you know when you have exceeded the duty cycle? The reason I ask is because while I was welding two plates together earlier it would weld great untill I stopped. I would weld probably about 4 or 5 inches then stop to look and when I tried to start back up it would more or less just pop the end of the wire, it wouldn't ever fire back up to actually weld unless I let it sit a little bit. Im using.030 solid wire with 75/25. I thought that maybe the wind might be blowing my gas away so I cupped my hand around the tip and it still didn't make a diferance. If I would just walk away a few min and come back it seemed to work fine. This normal or should I be looking at something else? Thx. Basically your both saying the same thing,. but in different ways. Basically, higher amperage, less welding time. As I understand your duty cycle should increase when your amperage decrease. In your example 20% @ 90 amps, if you're say at 45 amps your duty cycle should for instance be 40 %.
