AC/DC Inverter TIG/MMA Welder,250A Fully Digital Welding Machine with Foot Pedal,IGBT,VRD Function for Carbon Steel,Stainless Steel,Copper,Aluminum and Aluminum Alloys…

Update: The machine is fine. My challenge with aluminum was my flow meter. It overstated the argon flow. I used a cheap meter at the torch and after adjusting the valve, I was actually stacking even dimes that are shined with even HAZ. Nice unit..Full function machine in a small package at a good price. Very poor and limited manual. Consumables are low quality and the # 5 cup was threaded so it couldn’t make a tight connection. Annoying but ok at this price. I set everything up and tried to strike an arc. No luck with the foot pedal. I took the foot pedal apart and tested the potentiometer and switch which were good then the leads for continuity. I found the main cable was very loosely connected. The cable was clearly wired by someone without electrical knowledge.I have been practicing on aluminum and it’s not going well. It’s surely my lack of skill as the machine does strike and arc and is responsive to the settings. In all it seems to do what it is supposed to do. If I remember, I’ll update the feedback once I figure out how to actually use it properly.
