Feb 04, 2014 · WOW! A lot of very helpful replies,very quickly! (Sorry about posting in the wrong section I'd prefer to use the machine without the gas to be honest,I'am restoring an old camper van and the last one I did seemed to use a mountain of those tiny gas bottles and I don't want a large cylinder in the garage as its attached to the house.
ER309 - Weld WireWeld WireData is typical for ER309 weld metal deposited by Tig using 100% Argon as the shielding gas. Note:Parameters for tig welding are dependent upon plate thickness and welding position. Other shielding Gases may be used for Tig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration.
An electrode polarity chart based on AC or DC current and type of Stick welding electrode. This will help you choose the right stick for the welding job.
Gas for Mig welding stainless and mild steel - Miller Nov 13, 2005 · i'm making a tank for a home made tig cooler. The stainless i'm using is 400 series. The mig wire is 308. I will only be tacking the tank with the mig. The rest of the welds will be tig. I got my c25 refilled today, figured i would take a chance.
How Much Gas Does MIG Welding Use Welders LabMIG welders use a variety of gases depending on the metal you are welding, With mild steel, youll use a mixture of CO2 and argon. With stainless steel, youll use a tri-mix of helium, argon, and CO2. Finally, with aluminum, youll use pure argon or even argon with helium. #2 How do gas-less MIG welders work? Gas-less MIG welders work by using flux core in a tubular wire.
Good for outdoor windy conditions. Hotter than solid wires.) *Wire Feed Speed is a starting value only and can be fine-tuned while welding. **CO2 gas is economical and has deeper penetration on steel, but may be too hot for thin metal. 75% Argon
MIG Welding Gases - Choices and Options for Most Metals Sep 12, 2020 · Inert gasses used for MIG welding are Argon and Helium. The term inert means they do not react to anything unlike non inert gasses like oxygen that will cause metal to rust. The gasses used are what shield the weld from the air that causes weld defects such as porisity. Argon Gas Inert Gas.

If all of your planned projects and repairs fall within the parameters of this scenario, I suggest a 115v MIG welder using gas with .025 diameter wire. The smaller wire will make it easier to weld the 24 gauge material. .030 wire will have a higher deposition rate and could also be used.
Product Details - Hobart Brothers Performance Welding ProductsName:309/309L Sterling® AP:Brand:HOBART® Category:Stainless Steel Electrodes:Description:A lower carbon version of the 309(H) Sterling AP. Low carbon content makes it excellent for applications where reduced susceptibility to sensitization during high temperature service is necessary.
Stainless - Hobart Brothers Performance Welding Products308/308L ER308, ER308L Used to weld Types 201, 302, 304 and 308 stai
ASTM A743, A744 Types CF-8 and CF-3 and ASTM A240 Type 309S; For joining carbon or mild alloy steel to austenitic stainless steels; Can also be used on "18-8" steels, since it overmatches the corrosion resistance, if the weldment will not be exposed to temperatures of 538°C to 927°C (1000°F to 1700°F)
Stainless Steel MIG Welding Electrode Wire and Gas Sep 08, 2020 · MIG Welding Gas Welding of stainless steel is typically done with mixture of Argon and Carbon Dioxide gasses that can be as low as 2% carbon Dioxide to as high as 25% carbon Dioxide. In some cases there is tri-mix shielding gas containing 90% Helium, 7.5% Argon, and 2.5%Carbon dioxide.
TECHNICAL BULLETIN - MidalloyOct 16, 2009 · MIDALLOY ER309L BARE WIRE CLASSIFICATION AWS 5.9 Class ER309L / ASME SFA 5.9 Class ER309L UNS# S30983 A#8 F#6 FERRITE CONTENT 5 15 FN DESCRIPTION MIDALLOY ER309L stainless steel wire is used for GMAW, GTAW, and SAW welding. APPLICATION MIDALLOY ER309L is most often used to weld similar alloys in the cast or wrought form.
The weld shop has to MIG weld thin gauge (0.040 to 0.080), 300 series stainless parts with an 0.035, (1 mm) E309 MIG wire. The gas salesman has recommended the common three part helium tri-mix, (90% He - 7.5% Ar - 2.5% CO2). They have weld burn through and distortion issues so why is this global tri-mix gas mix a stupid choice.
When should I use ER308L, ER309L or ER316L? Welding SupplyUse ER309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to ER304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309.
welding - Can I use flux core wire with MIG shield gas Gas is needed with dual shield to shield the weld, but not with flux cored. So you can use reg flux core with gas, but you cannot use dual shield without gas. Dual shield is generally used for heavy fabrication, allowing a mig style process to really cram the welds in. It provides better penetration, and and less spatter, than flux core alone.
Data is typical for ER309L weld metal deposited by Mig using Argon + 2% oxygen as the shielding gas. Data on sub-arc is not presented, as sub-arc is dependent on the type of flux used. Other shielding Gases may be used for Mig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration
