1). For manual welding with 100% CO2, .045" ER70S-6 wire, and globular transfer, how many pounds of wire should I be able deposit before the contact tip needs to be changed? We use Tweco guns and consumables with threaded contact tips.
2). Same question as above but with 90Ar-10CO2 mix, .035" ER70S-6 wire, and spray transfer.
