FIELD TIPS — WeldIQ

▸Maintain consistent stickout (5/8 to 1 in). Too long = excess spatter. Too short = burnback.

▸Check gas flow before welding — flowmeter should read 35-50 CFH. Draft/wind will blow gas away; use windscreens in field.

▸100% CO2: more penetration but more spatter than mixed gas. Good for thicker sections and field work.

▸Open root: fit-up is EVERYTHING. Consistent root opening = consistent penetration. Check gap at least every 12 inches.

▸Use bridge tacks or tack from inside when possible. Tacks in the groove must be ground to feather edge before root pass.

▸Pipe: weld 12→6 clock on one side, then 12→6 on the other. Tie-ins at 6 and 12 o'clock need extra attention.

▸Internal purge may be required for certain specs (stainless, alloy). Check project requirements.

▸Verify preheat with a temperature-indicating crayon (Tempilstik) or contact pyrometer. Check 3 inches from the weld on both sides.
