Why do I recommend it to you? – Personal review: I didn’t think I could afford a welder at that price, but this one is incredible and allows me to weld anything, including metal. Although I believe specialists have been using this Ahp Alphatig 203 XI welder for years, based on the feedback I read, this machine provides everything that you require. I would buy this, but I think they’re just being somewhat picky.

The TiG/Plasma must first be converted to 220V before I’m able to use it. It travelled safely and was received in good shape. It appears to be well-made, and the firm appears to have modified it in reaction to some of the critiques I read. The hoses & consumables are bundled in zippered bags to ensure their safe arrival, and the air connection appears to be more durable. Once I get the 220V plug conversion, I think it will function well because it looks good.

Why do I recommend it to you? – Personal review: As a novice welder with no prior tig expertise, I purchased this. It has a top chart that indicates where to position each item according to what you’re welding and is highly user-friendly. Although you have to pick it up or stoop towards the floor to change the amp dial just on a foot pedal, I’m becoming used to it.

Since I’m new and don’t know any better, none of the nitpicky aspects that several reviews I reviewed complained about bothered me. This is a tig welder that I would, without a doubt, suggest to someone seeking their first one. I’ll buy from Eastwood once more. Regarding the tig welder, whatever they mentioned was accurate. And that matters to me.

Frequently Asked Questions (FAQs)

i.  Can we use any TIG welder to weld stainless steel?

TIG welders are versatile welding machines. Therefore they can weld stainless steel. But the welds’ age may not belong or stable for some low power and less precise TIG welders. So it is recommended to weld stainless steel using a good TIG welder.

ii.  From AC and DC TIG welding, which one is more favorable for stainless steel welding?

Most of the time, direct current is used for metal welding due to its deeper penetration. For stainless steel TIG welding, alternating current is more favorable due to the flipping of alternating current.
