planning to buy mig weld po... kailangan po nito ng argon gas at co2 gas, right? separate tank po ba ito or mixed gas @ 75/25 or 80/20? ano po kailangan... thanks

The mixed gas is just in one tank (cylinder) and its the 80/20 known more as Arcoweld. Then if you can find a supplier
of the 75/25 mixed gas, then well in good. May I suggest you find first a gas supplier of this arcoweld then proceed with
your plan for a Mig welder. You will also need an 8 lbs spool of mig welding wire. Be sure you have an ADH welding hood
to protect your eyes/face from the ultra violet rays. :whistle:

By the way you can use a mig welder without using shielding gas (mixed gas), that is if you will be welding with the
Fluxcore welding process. You will just need to buy a fluxcore wire.

Hope this helps.

Thats a good choice bro. It can accommodate 5 & 15 kls of mig wire and very convenient you can extend the control cable at your on desire. Enjoy welding.
