After recent discussions on here; I found an affordable used welder locally which I was able to pickup today. Hoping this will put me on until I can purchase the GYS I'm after. I'm hoping someone can help me with a few basic initial questions I have. As I have an existing welder already, numerous leads, clamps, etc and now the Clarke I would like to build a custom welding cart to improve mobility and organisation. The Clarke 151TE however comes with two wheels on the back and a protruding handle at the front, is there a means to remove these - while keeping the unit stable, so that it could sit on a custom made cart so it would be higher up? I've now got several disposable gas bottles which I plan to use up, when using these with the mini regulators, I noticed there is numbers on the regulator I picked up today should I just open this full, half way... what is recommended? When I'm done with each disposable cylinder, is there anything I need to be aware of; or can I just unscrew the regulator and screw it onto another disposable cylinder, until there all used up? The return lead on the Clarke 151TE is quite short and doesn't feel very robust, as I replaced the leads on my Stamos machine and added Dinse connections, I'd quite like to add Dinse connections to the Clarke so I can use my much longer and robust return lead I've already made up. Having had a look inside the door opening, the "tails" for the return lead enter into this portion of the housing and then disappear into the other side where all of the electronics are. I've not had an opportunity to remove the cover yet; would replacing these "tails" be a straight forward and easy to access process once the cover is removed? There might be enough slack to add a Dinse panel socket to the existing section of cable inside the machine (these I refer to as "tails"), but it seems better to me, to replace this connection in full, which is what I did with the Stamos. My local recycling center accepts empty spray paint cans as metal scrap, can used disposable gas canisters be treated the same way? I very briefly tried the new Clarke at the garage when I got back and it didn't trip the breaker straight away like my Stamos started to do so I suspect the problem with the Stamos machine lies within that welder. I also noted that the ka setting on the MCB's within the garage sub panel are 6ka, so I'll replace the 6ka 16a b type with a 6ka 16a c type when I get chance to hopefully avoid any problems down the road. Thanks everyone.
