Arccaptain Welder Settings Explained ( So Your Welds Stop Sucking )

What happens here

Set the ArcCaptain MIG 250 welder to the manufacturer's recommended settings for 8 gauge (1/4 inch) material using .035 inch wire, which translates to 20.7V and 342 IPM according to the presenter. The material used is 1/4 inch plate. Before welding, ensure the material is clean by removing any mill scale. Mill scale is the dark, oxidized layer on steel that interferes with welding. Also, check the wire stick-out (the length of wire extending from the nozzle); the presenter demonstrates checking it with welpers. The workpiece should be properly grounded; for this demonstration, the welding table is used as the ground.

Goal: Perform a weld on 1/4 inch steel using the machine's recommended settings

Tools and materials

  • ArcCaptain MIG 250 Welder ArcCaptain — Performing the weld
  • Ground Clamp — Establishing an electrical ground for welding
  • Welding Gloves Miller — Protecting hands during welding
  • Welding Helmet — Protecting eyes from arc flash
  • Welding Table — Work surface and grounding point
  • Welpers — Trimming wire stick-out
  • 0.035 inch MIG Wire — Filler metal for the weld
  • 1/4 inch Steel Plate — Material for the test weld

What they say

Hide

practice beads before you do it. All right, so I cut up some quarter inch plate. So let's go see what the machine says to run for quarter inch. So 1/4 in converts to 6 something mm. This wants us to run 28 vol 600 in per minute for 5 mm thickness. Let's give this a try and see how it goes. All right. So a couple things before you even start welding. One, make sure your material is clean. Get rid of all the mill scale. Mill scale is like it's that dark color stuff on top of your steel. Get rid of your mill scale. Clean up your edges. These are not the best, but clean up your edges. Bevel if you have to. Like if I was going to run this, I would bevel it. Run my route and then run two um overlays over the top. But I'm just going to do a T- joint. We'll run it like this. Um, another important thing to do is your wires stick out. What I like to do is I like to just take my welpers here, put it at the tip, and then whatever that stick out is is the depth of here. So, yeah, those are two things to start. Make sure you have a ground clamp. I'm grounding to the table. It's probably best to ground to your piece, but for this demonstration, the table will work fine. All right. So, I just went ahead and tacked these in. Now, let's run a bead. I want to be pushing instead of pulling. I want that gas shooting out in front of me. Let's go ahead and run a bead on here and see how it sounds. You should be listening to like a hissing noise. Like a not really hissing, like a crackling bacon type sound. That's hot. That's hot and fast. That's with the arc captain settings. All right. So, now we're running the Miller settings.
