Actually, It's pretty much spot-on for what you want. Clarke make the best cheap welders (anyone on here will tell you that) and the lack of outright power on the 105en is irrelevant, because for thin metal you'll be using it mostly on its lowest power setting. Hurrah!
Car panels usually need the lowest setting (which I think is 30A on yours), and you've got to take a bit of care to avoid burning through on thin panels.
The tutorials on here are pretty good though.
As you've probably heard already, an argon/co2 mix would be first choice, followed by plain co2, making gasless wire the last.
You could do it any way you choose, but gasless spatters and smokes quite a lot, which doesn't help you to see so well.
An auto mask helps loads too, and frees up your other hand.
I expect I've missed lots here, but others will be along soon, who know more than myself to fill in any blanks!
thanks for the reply`s guys. the welder i have is a gasless kit, i did buy a hands free mask and i also have a big reel of wire for use with gas.
how much am i looking to spend on a bottle of gas and a regulator?
£80 a year for a full bottle of Argoshield (the best stuff) inc bottle rental. £45 for a refill. Sounds a lot, but someone worked out the cost of the same amount of gas when bought as little disposable cannisters and it came to more than a grand!
Pub gas (C02) is ok if you want a cheaper solution. Beg, borrow or steal a black Co2 cannister and then ask your friendly publican to get it filled for you. It's not as good as Argoshield but is better than using gasless wire as you won't get as much flux spatter (the brown splashes and crust on the weld) or as much white smoke as you weld. This makes it easier to see what's going on with the weld pool as you go.
There are guys on here who know loads more than me (not hard...), so stick around a bit, ask more questions (I do!) and all will become clear.
As far as I can tell, this type of bottle comes complete with a regulator, so you'll just need an adapter. Weldequip or one of the other clever sods will be along soon to correct me....
You need a regulator. The bottle does of course have a nice convenient tap to keep in the gas.... but that's about all.
PM weldequip, he'll sell you a regulator. Or go to your local BOC or other supplier and get a co2/argon regulator with the appropriate fitting. Dunno what that is cos I can't remember. Fat lot of use I am!
