How does one set twin + and - dials to get right arc or go only in one directon?

the smaller one is for idle speed, the larger is adjusted at high speed to highest rpm and smoothest running. high speed and low speed jets. High speed is on top and is adjusted at full throttle.

If you receive this error message, the pattern selection dial was turned to select a pattern while the twin needle setting is selected.
Cancel the twin needle setting, and then select a stitch.

You may download a copy of the manual at http://ttselectrical.custhelp.com/ci/fattach/get/32003/1330261264/redirect/1/session/L2F2LzEvdGltZS8xNDE5MTA0NTY4L3NpZC8xSDdmaW9hbQ==/filename/ARC401.pdf

Check the dial indicator. Sometimes if someone changes the amps while welding, there will be a break in the coil. It will work at a different setting as long as you are away from the break.

Can you confirm the product model? The Motorola B802 is a touch-tone only phone.

The Voltage refered to is the Arc Voltage not the input voltage, for dip transfer the arc voltage needs to be 18-20v for spray transfer try 25-38volts both depending an the WFS setting. arc voltage is set on the voltage control dial. lets know how this turns out.#

Look on the front panel, you will see a dial with "-------" dashes underneath the dial. this is for stitch welding, turn this dial off, (anticlockwise). this is a timer for stitch welding and the dial is a timer. for continues welding this must be off. also some units have a spot timer, as above but has "......" dots under the dial, again this must be swithch off.

watch using matches to light a heater like this there dirty and cause problems in the long run long lighter for grills will save from extra garbage getting in the heater

Hi Mike,

The Dial/Swiitch Has A Fault, Or The Igniter Electrode is Touching, or too Close To The Contact Area.
Try Turning the faulty switch, left or right Gently.
Could be grease/dust arcing the Contact.
Broken Or uninsulated Wire Under The Ignitor, arcing against metal surface.
