375789 - Tweco Wire Feeder Pressure Arm Shaft

Restore Smooth Wire Feeding

Is your MIG welder stuttering, slipping, or feeding wire inconsistently? The problem might not be your liner or your contact tip—it could be the mechanics inside your wire feeder. The Tweco 375789 Pressure Arm Rod is the genuine replacement part you need to get your machine running like new again. This rod is the backbone of your feeder's pressure assembly, holding the arm that clamps the wire between the drive rolls.

When this rod gets worn out or bent, the pressure arm can't sit flat or apply even tension. The result? You crank down the tension knob, but the wire still slips, or worse, it crushes and deforms, leading to jams in the liner. By swapping out the old, worn rod for this fresh Tweco 375789 replacement, you restore the smooth, consistent pressure your drive rolls need to push wire steadily to the puddle. It’s a small part that makes a massive difference in your weld quality.

Don't let a cheap mechanical failure ruin your day or your welds. Keeping your wire feeder's internal components in top shape is the secret to frustration-free welding. This rod is easy to install and is built to the same high standards as the original part that came in your machine. Whether you are repairing a shop machine or fixing up a portable feeder, this part ensures you get back to laying beads with a consistent, reliable arc.

Why Replace Your Pressure Arm Rod?

• Eliminate Slippage: Restores the correct geometry so your drive rolls grip the wire firmly.
• Smoother Arc: Consistent wire speed means a stable arc and better penetration.
• Protect Your Equipment: Proper tension prevents motor strain and drive roll wear.
