Welcome to the forum Colin, never had one of those in my sticky welding fingers so can't personally comment on it's performance, 25 amps is not too bad for car bodywork, lower is better but not many hobby machines manage that.
sorry to say but complete rubbish , i had one managed to offload it to some poor unsuspecting soul for £20
The no gas welders are not much use for bodywork anyway i believe .
Personally id chuck it in a corner and get something a bit better , clarke are well reccomended on the forum for 'entry level' welders.
I should imagine the sparkle of getting your new welder has extinguished a tad reading what others think...that's always the danger of asking the question you did.
Back to reality:.. many people will say the welder is rubbish, many others will be using them to do the job they want and are more than happy.
Gasless is not as easy as gas to use, it is therefore more difficult to use gasless for thin metal repairs but not impossible, you just have to practice more.
Get some scrap bits and play away, see how it goes and what you think of it yourself.
I saw a restoration of an MGB done by a friend who had the oldest most battered cheapo gasless MIG in the world, that car now takes awards at shows.
well it looks as though this little guy will do fine it welds great, doing every job i ask of it, chassis, light panel work and its doing it well, i do seem to be doing really good welds so maybe my natural ability is helping
