Thanks bhai
Bhai it's a DC arc welder...probably the lowest and cheapest in market 
Market ma sab kehta haien don't buy less then 160amp....now you know these metal sheet are so thin and specially of my car as it's rusted...I can't give more then 20~30 amp so why would i need 160amp machine. Ab unko bta nae sakta ka mane kaam kea krna hai
i really want to buy 130amp gasless mig welders available in abroad markets but those are not available even no one knows about those welders.
gii bhai will cover them up after painting.
