Also keep a look at the duty cycle, and the operating voltage. If you go up in the performance you will also most likely change the operating voltage and the versatility of it.

the duty cycle is 20% @70 amps, the amp output is 35 -88, what does this mean and is this good?

I know it has a lot to do with welding time and amp draw. so here is the best way I was able to explain it.

(Duty cycle is a welding equipment specification which defines the number of minutes, within a 10 minute period, during which a given welder can safely produce a particular welding current.

For example, a 150 amp. welder with a 30% duty cycle must be "rested" for at least 7 minutes after 3 minutes of continuous welding. (When you are paying an employee for welding, anything less than 100% duty wastes money.)Quote"
