What The Pro's Think Of Eastwood Elite MP140i Multi Process Welder

Brian Kurtz - ASME & API Certified Welder

"The MP140i welds consistently with good arc stability just like the MP200i. It’d be great for the automotive guy welding patch panels, and lighter fabrication." Watch Video

Weird Beard

"This is an easy to use all in one welder that is compact in size. It plugs into a standard 110 volt wall outlet so it’s perfect for the diy home garage…it’s easy to get those professional looking welds we all like to achieve on our projects. Very easy to hook up. Capable of mig,tig and stick welding all in one machine. Very user friendly and super affordable. Far cheaper than buying 3 separate machines."

Duty Cycle

The rated Duty cycle refers to the amount of welding that can be done within an amount of time. The Eastwood MP140i has a duty cycle of 30% at 90 Amps. It is easiest to look at your welding time in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 90 Amps with a 30% Duty Cycle, within a 10 Minute block of time you can weld for 3 Minutes with 7 Minutes of cooling for the Welder.

If the Duty Cycle is exceeded, the Welder will automatically shut off, however the fan will continue running to cool the components. When a safe temperature has been reached, the Welder will automatically switch the Welder output back on. To increase the duty cycle you can turn down the Voltage Output control.


Always wear dry, protective clothing and leather welding gloves and insulated footwear. Use suitable clothing made from durable flame-resistant material to protect your skin. Thoroughly read and understand this manual before using.
