Welding gas bottles

[dom14]

That's the way mate there's heaps of company's and just as many prices to get your head around , gasweld were among the first to offer this system along with Linde , I changed the TAFE college from BOC to Linde and saved the TAFE a fortune in rental .
The refills were dearer but one large gas bottle of Co2 we had for 13 years and from memory our special rental rate at that time was $113 per annum but the gas was worth about $20 again a special Govt price .

Gasless MIG unit is an absolute PITA to use mate. I tend to think they are not good(or at least the Ozito one that I've got).
Weld tacks don't tend to be particularly weak, but they tend to form as chunks. It has high/low setting and 1-10 feed line speed setting.
I don't seem to be able to get good looking weld tacks by playing with those settings. Or there is still a possibility that I'm crappy at it.
