Please continue! I have loved the journey also. Welded my main triangle recently and wish I had practiced on these settings. Your exploration makes these clips accessible to us aspirational builders. I also use an aluminum heatsink with a mitre that I have on a threaded rod to access deep tube ends. Have you made your own BBS's as this is a good project also. can't wait for series II.
@PithyBikes8 жыл бұрын
Very clever heat sink placement! I haven't made my own BBS's, maybe some day. Right now I cannot because of the minilathe. It stinks at cutting steel. If I really finess it maybe it could work, but the time and effort would be too great. Thanks for the comment :)

The rule of thumb is 1.5 amps per thousandths of thickness. So, you set the amperage 4x high and then 25% duty cycle. Whatever works. Here's the usual way to do it: kzfaq.info/get/bejne/n9lgdbNknr6-fKs.html

Interesting, what kind of testing have you done on these frames? From what I know about 4130, you want some of that heat input and to cool it slowly because its very heat sensitive. It would be cool to see some destructive testing using your pulse settings vs straight foot pedal controlled weld.

@sweenep868 жыл бұрын
You're welds are fine but I think the pulse function prompts many people to weld to fast which limits your ability to maintain torch angle and Sri length especially on coped joints. Coped joints are also not fixed amp joints, they're essentially two lap joints and two fillets. I personally would use the pedal with 45a max, your fit up is great let the pool form and dab rather than laying the wire. The pedal will allow you ease off if its getting away from you. The stacked dime look will come from using the right sized rod and evenly timed dabs into the pool. The pulse setting is prompting you to weld faster than you're capable of and add more filler than required to stop it blowing through.
@PithyBikes8 жыл бұрын
+sweenep86 sounds good. I get varying suggestions on different methods. I've found its a matter of preference. Someone who really knows how to pulse I think can produce good strong welds. For me, I need a lot more practice. I'm trying to get better at moving fast because most of the feedback I get is to move faster to reduce HAZ. Thanks for the tips.

Wouldn't it be more beneficial to practice without a heat sink? You know, to replicate those welds where placing heat sinks isn't an option.
@PithyBikes8 жыл бұрын
+PUU-TAAH for bicycle tubing, most of the welds are with heat sinks. Only welds without are the drop outs. But some builders even make special sinks for those too! Not everyone uses heat sinks. But the other factor is the practice tubing is short. Most real welds involve longer tubing which also absorbs and disperses heat. Thanks for the comment!

@PithyBikes7 жыл бұрын
I think anything lower than 9 might show the arc too bright. I use shade 9 for thin wall stuff and it feels like the perfect shade to me for this. That said I never tried anything lower. Maybe it could be dangerous to go lower? I know one thing that helps with visibility is to avoid any lighting behind you that might reflect into your helmet from behind you.

whats the the benefit of the heat sink and the puls welding?
@PithyBikes7 жыл бұрын
The heat sink in this video is a temporary heat sink made especially for practicing. It's to simulate the real thing where I use a heat sink to weld actual frame tubes. Heat sinks are used to keep the heat affected zone smaller and reduce distortion on the tubes. Pulse welding also keeps heat down and reduces distortion if used correctly. However, some experienced welders can probably get the same results without pulse at all because they can move faster when welding. Hope that helps explain things.
@Gallardo66697 жыл бұрын
Pithy Bikes thank so much for your reply. if pulsing helps to reduce the heat then i miss another theory in welding,because the heat itself is actually needed to melt the material. but thx,i will need to learn more about pulsing. = )

Gallardo6669 the current comes in at a peak of % you set on the machine. so 20% pulse time on will be 20% of the total pulse will have max amperage the other 80% will be a % background current like 5% of 100 amps would be 5 amps hope that makes sense.
