Current first
Most sticking is too little current. The packet prints a range for the diameter — a 3.2 mm (0.13 in) rutile rod wants roughly 90 to 130 A — and the bottom of that range is where beginners set the machine because they are nervous. Move up. A rod that lights and stays lit is safer than one you keep breaking free.
Strike like a match
Drag the tip across the plate as if striking a match, then lift to about the rod’s own diameter. Tapping straight down is what welds the tip to the plate. If it does stick, twist the holder sharply sideways rather than pulling — pulling bends the rod and cracks the coating, which makes the next start worse.
What the machine can do
Hot start raises the current briefly at the moment of striking, which is the single most useful feature at this level. Arc force adds current when the arc shortens as you push into a joint. Anti-stick does the opposite — it cuts the current when the rod does stick, so you can pull it free without it glowing red.
Keep the rods dry
Damp coatings make an unstable arc and a rod that will not restart cleanly. Basic low-hydrogen rods are the fussiest; even rutile rods left in an unheated garage all winter weld noticeably worse than fresh ones.
The questions welders ask
My rod sticks only when restarting. Why?
Because the tip is capped with slag from the previous stop. Break it off against the bench or scrape it on the plate before restarting — many rods will not strike through their own slag, and basic electrodes are worse than rutile at this.
Is a scratch start bad for the machine?
No. Momentarily shorting the output is a normal part of stick welding, and inverters are designed for it — that is what anti-stick exists to manage. What is bad for the machine is running it above its duty cycle, which is a heat question rather than a striking one.
