My amps are pretty low. My big issue is purely skill and speed. I hover for too long and it gets too hot because I'm just too slow and unco. I know exactly the technique I need to follow and I know exactly the technique that I'm doing - which is wrong :tongue: 

So I've tried my best but it's a hand eye co-ordination thing that I just need to keep practising at. I'm fully aware that I might well never be an amazing welder, creating weld porn that I can show off.  But ho hum.  Hopefully in time I'll improve enough. 

Oh and I was using 1mm wire btw.  Just need to practice 

In fairness to myself, not a proper excuse but something that I'd change if I could afford it. My old jasic welder ain't that smooth at low amps. This I've had other owners of the same model machine tell me as well. Plus my torch is quite a hefty old thing and a bit awkward to hold when doing tricky bits. If I was to get into doing a load more thin tubing work I'd look to upgrading equipment but at this point in time that's not something my bank balance allows. 

Oh yip. Maybe the 1mm wire is a bit thin. I find 1.2 is a good size to feed in nicely. 1mm might be having to feed to much in so can be difficult to get smooth.

Approximately what amps are you running? 

You might be low. But looking at the inside you've got more than enough penetration so could afford to go lower yet.

I've got a boss weld 200x tig for at home stuff and the pedal is like you say not that smooth and can make getting nice welds harder than it should be.

It's one of those horrid pressed steel pedals. But it works ok. 

Just need to practice with it more and do more tube work! Honestly - there's only so much that paying about with settings can help when it still comes down to talent and experience. I know what to do and the settings to use.

Sometimes during this job when my stars aligned id get mint welds.

Other times it was lumpy. I wasn't really fussed about it looking perfect though - just strong. So I'd have to double pass on places to smooth it out and make sure it was a thorough well penetrated weld. Hence it can look really 'hot'. 

Give me a job on 1.5mm box section and I'm fine. I also do all previous stuff like that just with the torch trigger.

Thanks man. Yes-I do like a bit of sweeping and tidying. To me it's still a bit messy. I like the idea of a future bench build with cupboards to hide the stuff below the bench. Also going to paint the walls some nice bright colours to help brighten the place up. 

But finish this engine first.. I promise :grin:

A sports car and a Jag...

20230225_122458_(Custom).jpg

Had a good time racing over the Takaka hill on the way back from the Saturdays cruise to Golden bay with that Jag. I don't think the Jag Six was needing to put in as much effort as my little Datsun 1200 was up the hill :)

That was my favourite part of Nats. :D

Although your Imp looked a bit bouncy on the straights, the flip side was how easily it sped through corners while staying flat and keeping within its lane. Definitely a sports car.  :thumbright:

The Jag needed rather more of the road, despite sportier suspension and 100kg less weight in the nose than a V12 XJ-S has. With its brand new not-very-sticky tyres it would surf the bends like a speedboat, but at least now it was somewhat progressive and predictable/manageable/non-lethal (at lower speeds, in the dry). Probably as good as it gets? I enjoyed giving it the beans from halfway through the hairpins to deploy the Powr-Lok diff before the Imp got away... Once the Imp has flat 6 power, I'll be in trouble.

I was glad for the full brake rebuild on the downhill side with the motorbikes, but I was still using engine braking (and air conditioning braking) just in case. ;)

Yeah the imp corners very well considering its a 60s almost cheapest shopping car at the time, on its bone stock suspension and bushes but for the makita one way springs. 

Rides well too all things considered - but there's no way to hide a short wheel base, short travel, 750kg car on lumpy roads at speed :geek: or if there's a strong side wind added!
