2007年1月23日 · It is not recommended but can be used as a last resort. C25 ( 75% CO2 25% Argon ) and straiaght CO2 are both used on mild steel for general and certifed welding. Straight argon can be used on a mig for stainless and aluminum and Their maybe other argon mixes that may work better but I am not fimilar with them.

2017年5月4日 · 1. For CO2, open the cylinder very slowly. For argon-mixed gas, open cylinder valve slowly a fraction of a turn. When the cylin- der pressure gauge pointer stops moving, open the valve fully. 2. Set gas flow rate for 30 to 40 cubic …

2016年9月6日 · Yes the CGA cylinder valves are different on O2 and Argon. O2 is typically CGA 540 and argon CGA 580 so you can't accidentally attach the reg to the wrong cylinder. As far as possibly converting an O2 reg to argon use, maybe. The question then would be if the internal pressure the regs are set at match.

2011年5月29日 · We built argon and mixed gas headers for our welding school booths using automotive air chucks, and hung the individual regulators themselves from the QDs by replacing the inlet nipples (note they were on a LOW PRESSURE line of about 35 psi which is ample). Fed them from dewars (liquid argon) or cylinders as needed. Worked fine and is still in use.

2012年4月27日 · In many cases, a blanket that stays put will do the job better than several complete headspace volumes of nitrogen. Argon is the cheapest and most effective means for most inert gassing. In truth, gas cost is chump change. At 6.5 cents a cubic foot, an entire 1000 gallon headspace full of argon costs nine bucks. A barrel of argon costs fifty cents.

2015年11月16日 · If your welder has a gas fitting, just stop by any welding supply store and look at the Mig gas regulators. These regulators can handle 100% argon and mixed gases. Can even handle 100% CO2 for a short time with a bottle adapter. You will like 75/25 mix over 100% CO2. 100%argon is only used with aluminum wire and TIG machines

2016年12月21日 · Argon has a molecular weight of 40 while CO2 has 44. The molecular weight is directly related to the density of the gas. So 75% Argon and 25% CO2 mix has an average molecular weight of 41. That means that compared to pure argon, 75/25 mix is 2.5% more dense. So about 2.5% is how much the flow meter will be off. So no difference in real life.

2019年11月26日 · It depends on the model. My argon CO2 is 50-100 psi input. I’ve sold several and some require at least 100 PSI input. It’s usually stated on the label on the back. I posted a past mixer thread that gives the setting to use the argon CO2 with helium so you could probably use it in reverse if it’s calibrated for helium.

2013年4月1日 · It's a simple stupid question. O2 tanks have double seals and should be opened fully to prevent leaks. Acet tanks should only be opened partway to allow easy and rapid closing if need be. Does an argon tank have the same valve system as an O2 bottle? Or can it be opened a half turn and call it good?

2023年2月8日 · Sure, no problem other than making sure that your box contains only argon. Typically, an air tight glove box is used with a Schlenk line to purge the air after putting your materials inside the box. It takes a lot of argon to purge the last traces of air.
