Arc welder purchase.

The one you are looking at looks very much like a basic transformer machine. Duty cycle is rubbish. It will probably also have quite a high inrush current when you turn it on and if you have mcbs in your distribution board you might trip the circuit its plugged into.
The ESAB ones are great machines providing they dont break. If they do it wil cost you a fortune to get it fixed.
You might want to look at a small inverter machine like a Messer pico or maye a Thermal Arc. These are small light and very portable and will do a 3.2mm rod easily with a good duty cycle.
