The Perfect Choice

So far, it's perfect. I needed a multi-purpose welder for the garage, and spending over 1k was not an option. The right choice for me was this one! I have pushed this welder, 110v and 220v, and it does everything I wanted. PLUS, it has a plasma cutter. I went through 3/4" steel like butter. I have yet to try the TIG, but I will eventually when I get myself an Argon tank, but at no time soon. I'm not a professional, but I can lay down good beads with the Mig flux core, so it will be even better when I use gas! I looked at all the comparable units on the market, and they all work close to the same; for me, the duty cycle was higher than others, and the plasma included was the selling point. I'm thrilled with this welder, which is perfect for the weekend warrior.

Simder 4050 pro upgrade

I love this welder I have only used mig and plasma cutter. Buy I want to tell you it's worth the money. Jason yang and his crew took care of all my needs I appreciate all they did for me. Customer service was top notch. Shipping took a little while but Jason took really good care of me . Thank you Jason yang and crew.

So excited!!!!

Haven’t got a chance to use as the luxury pack with the helmet and other items to get started is still on the way writing this but the unit is as described and as I saw in all the reviews. I’m very excited to get the projects going with this price of equipment. Big things on the horizon. Thanks simder

Great multi function Welder

I was a little hesitant to purchase the SD-4050 pro. Now that it is set-up and fully operational, I could not be happier. The plasma cutter works great, the Mig welder ia also great. Have not tried the stick welder yet. Great little machine.

Christopher Whaley
